rolex yacht master 2 vs sky dweller

Mastering the Rolex Sky Dweller

In the past half-century, since it launched its GMT-Master, Rolex has brought out just two new complications : the Rolex Yacht-Master II, in 2007, with a countdown yacht timer, and the Rolex Sky-Dweller , equipped with both a second time zone and an annual calendar, in 2012. In this feature we explain how the Sky-Dweller, and its innovative movement, works.

The Rolex Sky-Dweller contains the in-house Caliber 9001. The second time zone is indicated by an off-center, rotating 24-hour disk. Local time, indicated by the center- mounted hands, can be adjusted quickly when you change time zones by setting the hour hand forward or backward in one-hour increments. The minutes, seconds, and second-time-zone indicators are not affected during this operation.

The calendar mechanism, which changes instantaneously (an annual calendar automatically differentiates between months of 30 days and 31 days, and need be adjusted just once per year, at the end of February) is relatively simple, Rolex says: the company has added just two gear ratios and four gear wheels to its existing instantaneous date calendar. As Rolex explains it, “The mechanism is designed around a fixed planetary gear wheel at the center of the movement. A satellite wheel engages with the planetary wheel and rotates, orbiting the planetary wheel in one month, driven by the date disk. The satellite wheel is fitted with four fingers for the four 30-day months (April, June, September and November). Click on watch photos for larger images.

“The gear ratio between the satellite wheel and the planetary wheel is calculated in such a way that at the end of each 30-day month – and only in these months – one of the satellite’s fingers receives an additional impulse from the date-change mechanism. This makes the calendar disk jump two days (from the 30th to the first) within a few milliseconds to display the correct date.” Rolex has dubbed the mechanism “Saros,” a Greek word that refers to the approximately 18-year cycle that can be used to predict when eclipses will occur. Rolex chose the name because it brings to mind the revolutions of the Earth and moon, which are like the motion of the satellite wheel (the Earth) with its four fingers (the moon). The Rolex Sky-Dweller calendar has an unusual month display. The hour numerals correspond to the 12 months of the year. Next to each numeral is a window. The window for the current month (e.g., “IIII” for April,) is black; the other 11 windows are white. (On the brown-dial model, the correct month is indicated by a white window for better contrast.)

To set the watch, you use both the bezel and the crown . First you rotate the bezel to one of three positions to select which of three functions — date, local time or home (24-hour) time – you want to set. Then, using the crown, you set the function, going either forward or backward. Rolex says, “The heart of the mechanism is a double cam and levers that engage various gear trains inside the movement according to the function selected. One of these cams is activated by pulling out the winding crown; the other is driven by rotating the bezel [Rolex calls it a “Ring Command Bezel”] to activate setting wheels located in the middle case of the watch.” Caliber 9001, which has bi-directional winding is, like all Rolex calibers, certified by COSC . It has a stop seconds function and a power reserve of 72 hours. The movement has 380 components and is protected by seven patents, four of them new.The case is 42 mm in diameter and water-resistant to 100 meters. The Rolex Sky-Dweller comes in white gold, yellow gold, rose gold, on matching bracelets or leather straps, and in a version with case and bracelet made of Rolex’s proprietary Everose gold. Prices range from $38,150 to $48,850.

I want to have information of only Rolex watches new and old

I only whish the yellow gold model had roman numerals iam waiting to get it

Nice but not my favourite Rolex.

This watch was designed by a gentleman while sitting under the ugly tree,much like every Rolex watch ever made.What about some genuine creativity. John Landy

J E A L O U S.

Innovative? Yes. Ugly & overpriced? Yes. Sky Dweller is another model that the market accepted lukewarmly. It seems that Rolex has lost its knack with certain lines.

Design likes are subjective and many may agree with you. One thing undeniable is the typical Rolex architecture in design of a watch with an advanced movement which subtly provides dual time zone performance along with a full calendar needing to be adjusted once every five ur years with its chronometer movement. This watch is not often in stock at jewelry stores as there is significant demand for the production.

Is it a Vacheron Constantin or Patek’s?…No. It is defineately Rolex styling and a typical Rolex movement, designed to last generations.

Seriously considering the yellow gold model of Sky Dweller. Love the watch and its features but already have two Rolex watches recently purchased. Date Just II looks a lot like the Sky Dweller, even to the Champaign dial. We’ll see…

The case is 42 mm in diameter and water resistant to 100 meters. —- WRONG! water PROOF….***

We agree that the Rolex Sky Dweller is the most intricate and amazingly innovative automatic winding watch in the marketplace today!

I love my yellow gold model. It has become one of my favorite time pieces.

If only rolex had not overlaped the lower numerals with the 24hr disc this watch would have been perfect.

I agree with Anand.

I also agree with Anand. With the additional comment that it looks strikingly similar to the Date Just. They must be thinking what works for one model will work for another. –Chris

After the Explorer II, this is probably the best looking Rolex out there. Love the white gold version. If only I had enough time (read: money).

The Skydweller Is the Most Bonkers Watch Rolex Makes

It looks like no other timepiece from the brand. And it functions differently, too.

By Zen Love

Welcome to Watches You Should Know , a biweekly column highlighting important or little-known watches with interesting backstories and unexpected influence. This week: the Rolex Sky Dweller.

Underpinning almost every swanky or blinged-out Rolex is a tool-watch ethos. That means traits like practical design, legibility, robust build, automatic winding and, for the most part, simple functionality. It’s a formula that works exceedingly well and results in conservative watches that rarely require substantial updates. This is exactly why the the Sky Dweller stands out: it’s the brand’s most complicated watch and, frankly, it’s pretty funky for a Rolex.

Aside from the time and date, most complicated Rolex watches might feature a single additional complication such as a GMT or chronograph . You’ll even find a moon phase in the Cellini collection. Introduced in 2012, the Sky Dweller, on the other hand, features not only two complications, including a GMT and the rather involved annual calendar , but also unique ways of displaying information and controlling its functions.

The annual calendar tracks the month and date, differentiating between months with 30 and 31 days and only needing adjustment once a year, on March 1st. Rolex’s 9001 movement inside accomplishes this with only four additional gears on top of the existing architecture that displays the date — a solution that, by its very simplicity, helps keep the movement nice and robust. The display is equally unique, with an unobtrusive window next to each hour that symbolizes one of the twelve months of the year. For example, the window next to three o’clock will appear black or red (depending on the model) to indicate the month of March.

This is pretty complicated and unconventional for Rolex, but in addition to that is an off-center 24-hour ring to indicate a second time zone. This is a healthy amount of displayed information, and it’s all controlled by a traditional crown — but with a twist, so to speak. The crown is used in concert with the bezel in a system the brand calls Ring Command. In this system, the bezel is used to select a mode (e.g., one of the functions), and the information is then set via the crown.

In the second position (the first is neutral) you can move the main hour hand back and forth in hour intervals independently from the minute hand. The next position moves the minute hand, main hour hand and the 24-hour disc. It might sound a bit confusing, but it becomes intuitive as soon as you use it once or twice, and is in fact a pretty elegant and innovative solution — not to mention handy for traveling. Finally the last position controlled by the bezel lets you set the calendar information (in both directions, it should be noted, unlike many common and lesser watch movements).

Echoing its dive-watch cousin, Rolex’s Sea Dweller , the Sky Dweller’s name tells you right away that it’s a watch for pilots or travelers. While Rolex also serves those general demographics with its GMT Master II and Air King, the Sky Dweller is meant for another level of globetrotter: the one flying first-class. Like certain other Rolex collections, the Sky Dweller isn’t available in an all-steel model. The closest you’ll get is the most affordable configuration with a 42mm steel case and bracelet but a bezel in white gold.

That’s where the collection starts, at $14,800, reaching cruising altitude in full precious metals at almost $50,000. This is unambiguously a prestige statement watch that stands out even among Rolex’s collections, and it almost feels out of character for the careful and calculated brand. But like any Rolex watch, it’s got decent water resistance (100m), a solid base movement — and is made to be worn.

The Rolex Heavyweights: Rolex Yachtmaster II Vs. Sky-Dweller

This Rolex heavyweights showdown is an all-gold version. We take a closer look at two watches that fit as Rolex heavyweights. These watches are absolutely heavyweights in the Rolex high-end luxury sports category. Here are the Rolex Yachtmaster II and the Sky-Dweller 

These watches carry a presence similar to only a few other timepieces. However, the question really arises when you are out there searching for a quality gold Rolex. In such a situation, which one of these Rolex heavyweights will be your perfect choice and for what reasons?

We aim to help you find answers to these questions by comparing these Rolex heavyweights over three distinct parameters. These are: 

• Their designs
• The movement they feature
• Their wearability and functionality

From these comparisons, we will pick a winner and that will be our recommendation. This will be the timepiece with the highest score from these three rounds. Follow through!

The Battle Of Designs Between These Rolex Heavyweights

The rolex yachtmaster ii.

Just as the name implies, the Rolex Yachtmaster II comes with a design made specifically for water conditions. This timepiece features purpose-built ability for competitive sailors. 

Generally, the most striking traits of the Yachtmaster II are the same features that distinguish it from others. Amongst other ocean-faring timepieces in the Rolex range, this timepiece features are distinct.

This timepiece features a stunning white dial blended with blue hands. That color mix provides a ton of contrasts that aid its legibility. More so, the gold-edged hour tags and the small-second dial put in that taste of luxury to its aesthetics.

Rolex again did a great job by keeping the dial as clutter free as it can. Based on the amount of details on display, a clutter-free dial is a no-brainer. 

The Yachtmaster II comes with a royal blue cerachrom bezel. Additionally, it features a 0-to-10 countdown track that comes in handy during regatta races. In these races, competitors get a 10-minute warning prior to the start of the race.

Here is a complication that is practically a programmable 10-minute flyback chronograph. That sounds rather more complicated than the real deal. Yet, from a graphical perspective, this is what makes the Yachtmaster II different in the Rolex collection. This feature pleasingly contrasts the colour of ether steel. 

The Case And Bracelet

Furthermore, the Yachtmaster II comes with a trusty Oyster case. This timepiece comes fitted with an Oyster bracelet. You can consider these Rolex heavyweights as a super-sized version with its 44 mm diameter size. 

Moreover, the chronograph pushers come in a nice rounded design. Yet, they do not have the screw-down locks featured on the Daytona timepiece. 

The Rolex Sky-Dweller

Similar to every other Rolex timepiece, the Sky-Dweller carries its design for a purpose. This design allows regular travellers the ability to track two time zones. The difference it has from the GMT Master II is that it displays both time zones simultaneously and in real-time. 

Your first look at the Sky-Dweller will appear like it is an oversized Day-Date with a fluted bezel and a large Oyster case. However, what gives this timepiece away is its distinct dial. Thanks to the huge numeral hour markers and offset white ring, the Sky-Dweller looks different. There is a clear difference between this watch and other models in the category. Thanks to the unique dial, it offers incredible legibility even from a glimpse.

The Annual Calendar Complication

Another impressive addition and one that we mostly miss out on is the annual calendar complication. This complication comes with the Sky-Dweller. You find it around the exterior of each hour marker. It appears like a small rectangle that fills in black to signify the month of the year at the time.

More so, the rectangles not in use are polished in the exact colour the dial comes in. Hence, they easily blend in and make additional room. With this additional room, the dial appears a lot less jumbled than a regular annual calendar timepiece.

It is even more remarkable considering that it also comes with a second time display built in. This one right here is a totally ingenious piece of engineering and design masterclass from Rolex.

Right before us, we have two huge, daring and highly functional Rolex heavyweights. For these two watches, each carries its own distinctive design shades and also fan bases. 

We mostly commend the design of the Sky-Dweller dial. Also, the slightly smaller size makes it more desirable. Hence, it is our winner in the design battle.

Movement Features Of The Yachtmaster II And The Sky-Dweller

This Rolex Sky-Dweller takes its power from the Rolex calibre 9001. This timepiece remains one of the most complicated movements ever produced by this Swiss watchmaker. This is of course a fully in-house manufactured caliber. 

Moreover, it comes with a purposeful design to particularly serve the Sky-Dweller. The Rolex brand is not your number one brand when it comes to making watches with complications. Therefore, for them to create a watch featuring a date display, dual time zone and an annual calendar is no small feat. 

It was nothing short of big news when the timepiece hit the watchmaking world in 2012. In addition, this 9001 caliber comes with a power reserve that lasts for as long as 72 hours. There is also a frequency of 28,800hz. Lastly, like every other Rolex perpetual movement, this one carries certification from COSC.

On the other hand, the Yachtmaster II is slightly less complicated compared to the Sky-Dweller. However, it still parades certain outstanding technology that makes it better than most watches in the Rolex collection. 

This watch takes power from the Rolex caliber 4161 movement. It is just like the 9001 caliber. The 9001 features a power reserve of 72 hours and is COSC certified, the 4161 caliber has the same features. 

Meanwhile, the 4161 captions what is in practice, a flyback chronograph complication. This is a feature you can find in this Regatta timer. This feature reportedly took Rolex 35,000 hours to create. Finally, one of the patented abilities contains 360 elements alone!

These two Rolex heavyweights carry sophisticated movements. These movements bear specific features that help to power all of the watches’ outstanding abilities. Similar to all Rolex watches, the movements are calibers made in-house by Rolex. That explains why they are among the most durable and precise movements in the mechanical watch world.

For this category, we cannot declare an outright winner. The fact remains that all these watches bear specific design fit for particular uses. Hence, they have the complications fit perfectly for their intention. For example, the annual calendar in the Sky-Dweller is remarkable. Yet, it just wouldn’t be fit when placed in the Yachtmaster II. In the same light, a flyback chronograph will not make sense in the Sky-Dweller. 

This ends in a stalemate!

The Wearability & Functionality Of The Rolex Heavyweights

What is the plan when comparing the wearability and functionality of timepieces? In such a case, we simply want to see how comfortable they are on the wrist and how their function helps. This same intention applies to these two Rolex heavyweights. 

What are the distinct functions of the Yachtmaster II and the Sky-Dweller? What makes each of these timepieces desirable to watch enthusiasts? Which appears more on the wrist and wears easily? Keep reading to find out. 

We begin with the Yachtmaster . Here, the bright white dial is highly legible. Therefore, it easily shows all the essential details at a glance. So, imagine you aboard a speeding boat and you can still see what is on your watch clearly. That is awesome!

Moreover, the  regatta timer display featured on the timepiece is another very clear element. This is thanks to the red defined arrow that points to the present minute in the countdown timer clearly.

Furthermore, the functions of the watch are very unusual. This is one style only the Yachtmaster carries. This timepiece employs a ring command mechanism to fix the regatta timer. Hence, you as the user must first rotate the bezel 90 degrees to the left. Afterward, you then press the reset pusher in a way that it stays depressed. 

Thereafter, The crown then must get unscrewed back to the initial position. It is from this position that it can then get turned to set the needed number of minutes the countdown timer should have. It is always between 1 to 10 minutes. 

As soon as the minutes get selected, the bezel gets rotated again to the first position. That resets the pusher. 

Also, you only have to screw the crown back in to guarantee the water resistance function. Then, the timer gets started. You can also stop it using the top pusher. More so, the timer can also be reset on the fly as that synchronizes it with a different time source. 

When placed on the wrist, the Yachtmaster II is a heavyweight really. Yet, it is comfortable. Also, the Oyster case and strap are good to wear regardless of the metal option used. Lastly, the deployant clasp comes with a double-lock. That ensures the timepiece remains fixed on your wrist.

The Sky-Dweller does not have quite the legibility the Yachtmaster has, especially in the Champagne dial variant. We say this because we tested it.

However, the figures have enough spaces between them. You can read them with a mere glimpse. Also, the addition of the annual calendar to the dial is very commendable. We believe it’s perhaps one of the most creative means of revealing the details this timepiece carries.

Furthermore, the Sky-Dweller similarly features a ring command mechanism to run the wristwatch. However, unlike the Yachtmaster II, this one helps to set all of the functions. Meanwhile, the bezel comes with four selectable positions. Each of these positions alter the performance of the crown. 

This requires a little getting used to if you must make the most of it. However, the functionality of the Sky-Dweller is more preferable to pulling out fiddly crowns for these same functions. 

Additionally, the tactile response from the bezel as it clasps into the successive position satisfies in every sense of it.  

The Sky-Dweller on the wrist presents the same wearability as the Yachtmaster II. First off, the Oyster case and bracelet do not give any uneasiness at all. Plus, the narrowly smaller width and height of the case presents a strong covering to it across hard surfaces.

But, there is one shortcoming we will love to criticize here. And, that would be the deployant clasp that only has one lock phase. Being a timepiece set in rare metals, the twin lock system would provide better security compared to this deployant clasp. 

To be frank, we found it hard to declare a winner in this category because it is a really difficult one. The truth is that these two Rolex heavyweights have amazing means of delivering their functions. Plus, they are both comfortable timepieces on the wrist. Becoming an owner of any of these two watches will certainly be a pleasure. 

Nevertheless, we would not want to call another draw in this battle. If we must be frank, the way the Sky-Dweller wears on the wrist is quite preferable. In fact, the ease it gives you through your day-to-day life is remarkable. 

With an annual calendar and a second time zone, you have more helpful functions compared to a chronograph timer.

Final Ruling

Eventually, we have an overall winner in this battle of these Rolex heavyweights. The Rolex Sky-Dweller takes this one with two wins to one over the Yacht Master II.

We must commend the overall structure of this timepiece together with the incredible movement in it. Also, there is a distinct way its functions operate. 

For the Yachtmaster II, this watch is great in its own right. Yet, we believe it’s slightly more niche compared to the Sky-Dweller. 

Regardless of any of the two you go for, you are certainly getting an exceptional timepiece that will serve you.

Hands-On: Rolex Sky-Dweller Watches Updated For 2023

Launched over a decade ago, the Sky-Dweller is a fascinating, albeit compromised Rolex watch worthy of attention. In typical Rolex style, the Rolex Sky-Dweller watches updated for 2023 carry over just about everything that has made the collection great while introducing minute and not-so-minute improvements and modifications.

As a start, here are a few points to remember about this steadily expanding watch collection. The Sky-Dweller is the most complicated Rolex watch in production today, thanks to its combination of an annual calendar complication with instantaneous displays that jump at midnight, two time zones, and a Ring Command system that enables the rotating bezel to act as a crown function selector. The Sky-Dweller is also among the biggest, widest, thickest, and heaviest Rolex watches ever made, and we have sampled all three of its new-for-2023 model variations: The White Rolesor version with Oystersteel case, bracelet, and 18k white gold bezel; the “baller” all-gold-everything 18k Everose variant; and the solid 18k white gold piece matched to a lightweight, “high-performance” Oysterflex bracelet. Let us discover which combination of materials best suits this “elegant and trusted companion for world travelers,” as Rolex puts it.

For almost 80 years, since the first all-gold Datejust debuted in 1945, it has been difficult to overstate the presence of an all-gold Rolex watch. Over that time the Day-Date, Submariner, and, much more recently, the Yacht-Master II have perpetuated a legacy of “holier than thou” wrist-bling through ever larger and bolder cases, bracelets, and dials. The Sky-Dweller doubled down on this when it debuted in 2012 in nothing else but solid gold, or be it exclusively with leather straps. Measuring 42mm wide, and 13.8mm thick, the Sky-Dweller is one of the largest Rolex watches, and also a medium-large watch in the greater scheme of things that wears larger than that 42mm figure would suggest. Notably, this effect is further emphasized by the turning of the large watch trend, which is to say that despite its elegant and un-sporty design, the Sky-Dweller is not a discreet watch by any stretch of the imagination, and especially not in yellow or 18k Everose gold.

If you want a solid 18k gold bracelet on your Sky-Dweller, as it stands, you have limited options as only the Oyster three-piece link style is available (the five-piece link Jubilee only comes in steel on the Sky-Dweller) and you can only have 18k Everose gold or 18k yellow gold as there is no Oyster bracelet in white gold or platinum. This is odd because the GMT-Master II does come with an 18k yellow gold Jubilee, and the Sky-Dweller is available on an Oystersteel Jubilee, so it might be a matter of time before a gold Jubilee bracelet option joins the Sky-Dweller collection. This is important because, with the wide, flat(-ish) links of the Oyster bracelet, the gold Sky-Dweller is an absolute beast of a watch that is as heavy on the wrist as it is on the eyes.

Introducing changes that can be measured in fractions of a millimeter is this new-for-2023 model you see above, called Rolex Sky-Dweller reference 336935. Until now, there used to be a difference in the lug width measurement of various Sky-Dweller watches, as the first gold models on an Oyster bracelet had a 21mm lug width, while those sold on a leather strap had a 22mm opening. The larger width was taken over by the Rolesor (two-tone) versions in 2017, and it is now, in 2023, that the yellow gold and Everose gold Oyster bracelet-equipped versions adopt this wider, 22mm lug design.

In parallel with this move, the center links of the gold Oyster bracelets of the Sky-Dweller watches have 0.5mm wider center links. Such a move makes the watch head optically smaller, which is not a bad thing given the high volume of the Sky-Dweller. The lug-to-lug measurement has been increased by 0.3mm, hinting at a slightly redesigned lug and case profile. Also new here is the dial Rolex refers to as “Blue-Green,” not to be confused with the Bright Blue dial on the Oystersteel-cased reference 336934 that actually costs a bit less than a third(!) of this all-gold model.

Also new is the Sky-Dweller reference 336934, a watch in White Rolesor, which is Rolex-speak for a watch that uses Oystersteel for most all of its exterior and 18k white gold for certain parts such as the bezel, center links, and crown — but it is just the bezel that is in 18k gold when it comes to the Sky-Dweller. Nuanced changes here include the aforementioned 0.3mm added to the lug-to-lug which aligns with what we saw with the 2023 redesign of the Rolex Daytona, where the steel version adopted longer lugs ( to its detriment, we thought ). Difficult to spot, but also new is a thinner seconds hand — which is as minute an alteration as they get, again, in typical Rolex fashion — and the fluted edge of the crown also appears to be thinner, symbolizing Rolex’s quiet efforts to make the Sky-Dweller a bit more gracious.

If you can’t live without a Sky-Dweller in 18k white gold, you can only have it on an Oysterflex “high-performance elastomer” strap. There is no solid 18k white gold bracelet available, so as to better optically differentiate white gold from White Rolesor. Oysterflex-equipped Rolex watches could often be ranked among the weaker value propositions from Rolex today, as they are just $8,000 less expensive than those on a solid gold bracelet, which is not much of a premium to pay for a full-gold Rolex compared to one on a strap — but hey, kudos to Hublot for establishing such a strong market for rubber strap-equipped solid gold watches.

A closer look at the dial reveals a telling little detail: The Rolex crown is now present at 6 o’clock (twice, in favor of symmetry) which on a Rolex watch means that a new-generation movement has been installed in the watch. In 2023, the Sky-Dweller debuts the 9002 caliber, a development on the 9001 that has powered it for over a decade. Modifications include the incorporation of the nickel-phosphorus Chronergy escapement into its design, which is a high-efficiency, Rolex-developed escapement that has played a significant role in bringing some of its two-day power reserve watches up to three days. Strangely, the Sky-Dweller sticks with the three-day autonomy that it has had since 2012, and so it is the stronger anti-magnetic properties and the greater efficiency of the escapement (and hence yet greater accuracy over a depleting power reserve) that owners might take advantage of.

In conclusion, the Sky-Dweller quickly (by Rolex standards) grew into a versatile collection not just in terms of design and choice of materials, but also in terms of value proposition. The Rolex Sky-Dweller in White Rolesor (Ref. 336934) is priced at $15,650 USD and it is a ton (almost literally) of watch for that money. Presenting an annual calendar with a peripheral layout for the month and the added horological flex of instantaneous displays together with a second time zone, the addictively tactile Ring Command system, a 72-hour, 4 Hertz, remarkably accurate movement, and Rolex build quality, is an extremely strong proposition for just under $16,000. The Rolex Sky-Dweller wrapped fully in 18k Everose gold (Ref. 336935) is priced at $50,900 USD , demanding the stratospheric (and ever-growing, still) premium that an all-gold Rolex tends to have, but in return delivering the power-factor anyone who buys a colored gold Rolex is after. Last, the Rolex Sky-Dweller in white gold on an Oysterflex strap (Ref. 336239) is $42,700 USD representing the worst value-for-money here, which isn’t shocking from products designed to cater to those who want the latest trending luxury product — which the 18k gold Rolex (or Patek Philippe, for that matter) on a rubber strap definitely is.

Rolex reach for the skies with the Sky-Dweller

Editor’s pick: The Rolex Sky-Dweller is, along with the Yacht-Master II, the most complex offering in the brand’s current catalogue. Two time zones, an elegant calendar and a very, very cool bezel make for a serious piece of watchmaking. Add in the simplified dials and Rolesor cases of this latest batch and it’s a watch that’s stratospheric. 

For years, the Sky-Dweller has been one of the most interesting and least understood modern Rolex es. It’s one of the most complicated watches in their lineup, as a luxury traveller’s watch, and is the patrician elder brother of the tool-like GMT-Master II. This niche proposition, along with its solid gold offering, always made it something of an outsider Rolex. Until now.

In some ways the case of the Sky-Dweller remains identical to the version released in 2012, but viewed a different way, the changes to the big 42mm case represent the single biggest shift to the model, which has seen it rocket to the top of many a fan’s list. It’s all about the material. For the first five years of its life, the Sky-Dweller existed only in precious metals: white, yellow or Everose gold. Not only did this place the watch into a premium price bracket, but it was also every inch the solid gold Rolex — unavoidably so with that large, fluted bezel. But as Baselworld 2017 rolled around and the Rolesor Sky-Dwellers were unveiled, the proposition suddenly changed. Fifty grand plus suddenly came down to around twenty, bringing the Sky-Dweller within reach of a whole lot more people. Rolex released two Rolesor versions — yellow gold with a precious bezel and centre bracelet links, or a white gold option where only the bezel is made from the precious metal.

Aside from the case, the other major change to the Sky-Dweller is the design of the dial. And not just that stellar starburst blue option. Gone are the radial Arabic or Roman numerals, replaced with elongated applied batons, filled with Chromalight. This one change makes a huge difference to the simplicity of the dial. That and the fact that the second time zone disc is now colour matched to the dial rather than contrasting. Aside from these cosmetic upgrades, the Sky-Dweller’s dial is still the same legible design that smartly packs a lot of information into a small space. The most obvious feature is the second time zone, displayed via an off-centre 24-hour display. There’s also a dual calendar, with the date displayed under the traditional Cyclops and the month subtly indicated by a red marker at the outer edge of the hour markers. Every time I see this month implementation, I’m beguiled by its simplicity, and it still confounds me that it’s not a more popular style of calendar (Rolex is the only volume brand who use it, to my knowledge).

It might be too much to say that this simplified, somewhat sportier dial is an improvement on the dial of the all-gold model, as that watch has a different personality to the Rolesor. But I am quite confident in saying that this new dial will appeal to a wider audience. Extra points for the cutouts on the hands so as to always allow maximum legibility of the home-time dial.

The movement

The most impressive part of the Sky-Dweller is the movement. Not just because the Calibre 9001 is a highly complicated, modern movement with a mighty 72 hours of power reserve and protected by seven patents. No, it stands out because of how you interact with the various functions. You see that pretty fluted gold bezel? That’s not a regular bezel, it’s actually quite an ingenious piece of user-friendly engineering called the Ring Command. Twist it to the left and you’ll notice it has three distinct positions. Change the position of this bezel, and the crown changes a different complication. The third position (hard left) allows you to change the home time, the second position changes local time, and the first position allows you to change the annual calendar.

It’s an innovative, over-engineered and user-friendly solution to a problem you never knew you had. Just the sort of innovation that Rolex excels at.

The bracelet

No surprises here. Of course the Sky-Dweller ships on the Oyster bracelet. Now, if you opted for the white gold Rolesor version, the bracelet is solid 904L steel. If yellow gold is more your jam, you get polished yellow gold centre links. Solid and supremely comfortable, thanks in part to the easily adjusted Oysterclasp, which gives you around 5mm of flex room to ensure maximum comfort.

On the wrist

The large case size and that light-flinging fluted bezel make the Sky-Dweller an attention-drawing watch, and the fact that it’s not solid gold only reduces the bling-factor so much but, honestly, you’ve just got to embrace it. Aside from that, it’s the typical flawless Rolex experience.

The verdict

The Sky-Dweller has always been a great watch, and now, with its smartly redesigned dial and more accessible case material, it’s just a little bit greater.

Talking point

Let me show you my Ring Command Bezel …

Who’s it for?

There’s no doubt that the Sky-Dweller is one of 2017’s ‘it’ Rolexes, along with the Sea-Dweller. But if you prefer brains over brawn, the Sky-Dweller might just be the one for you.

What would we change?

Watches like this always make me regret including the “what would we change” part of the review. Everything here is so considered and so thought through that there’s really not much to say. However, I included it, so there’s no getting around it. If it were up to me I’d love it in a slightly smaller case. Failing that, a bezel that’s a tad less extravagantly fluted would be right up my alley.

Rolex Yacht-Master VS Yacht-Master II.

A detailed comparison on these two luxurious Rolex sport watches.

The Yachtmaster II and Yachtmaster 40mm are both great sports watches especially with professional sailors and yacht racers. They both are classy and sporty at the same time. But what are the key differences and what makes these two watches special in their own way? Have a look below at a detailed description of the differences.

Rolex Yacht-Master VS Yacht-Master II

Let's take a look at one of the latest and most spoken about Rolex Yachtmaster watches, the 116655. This watch is a special watch for many reasons. Namely, this is a historical landmark for Rolex since it is the first Rolex watch to ever use a rubber strap. Most people wouldn't bat an eye at the idea of a Rolex with a rubber strap so why the fuss? This is not any typical rubber strap. Rolex has been raving about this new rubber Oysterflex bracelet which is not only very comfortable to wear, it is also hypoallergenic.

The research and development team at Rolex has engineered a bracelet that is as easy to wear as a rubber bracelet but also holds its shape like a metal bracelet. They do this by using nickel-and-titanium inserts inside the band. They also instituted a patented shape on the inside of the bracelet which has a cushioning system built-in to it which allows the bracelet to take the natural shape of a wrist making the Oysterflex possible the most comfortable rubber watch band. An Oysterlock safety clasp keeps the watch from opening and looks stunning in 18ct Everose gold. Everose gold is a patented 18kt pink gold alloy that is unique to Rolex watches and has been used with all their pink gold oyster cases since 2005.

You'll also find a black matte Cerachrom dial which is a hardened ceramic material that is a tough and highly scratch resistant material that has anticorrosive properties and is impervious to discoloration from exposure to Ultra Violet rays. Perfect for spending your days relaxing on the deck of a luxury yacht.

The dial on the Rolex Yacht-Master 116655 with its cyclops date magnifier could be passed as that of a Submariner if it weren't for all the Everose gold used. You can find this material used on the rims of the index hour markers, the Rolex logo, and luminous filled hands. You won't find rose gold on the dial of any watch in the Submariner series (yet?). The combination of black and Everose gold is a real eye-grabber giving this the look of a really luxurious watch.

What's running inside this stunning watch? The Yacht-Master 40mm runs off an automatic Rolex perpetual movement, the Rolex caliber 3135. This 31 jewel movement beats at 28,800 vph and has a power reserve of about 50 hours.

Rolex Yachtmaster II

At a glance, this watch is an impressive piece of eye-candy with a polished case and two-tone rose gold and stainless steel bracelet. The design used vibrant colors from the blue Cerachrom bezel to the rose gold pushers and patented Triplock crown. The white dial is equally full of harmonic colors with blue steel hour, minute and subdial seconds hands and rose gold and red chronograph hands. A rose gold rimmed sub-dial and applied rose gold rimmed index hour markers tie it all together.

A unique feature of the Yachtmaster II is the regatta chronograph and features the world's first mechanical programmable countdown with a memory. You can accurately sync the watch with the starting sequence of a yacht race.

Unlike most bezels which don't operate as a component of the movement, the easy-to-use and bi-directional Ring Command bezel on the Yachtmaster II operates in conjunction with the regatta chronograph as an integral component of the movement. This bezel is the method in which you can synchronize the countdown timer to the start times of a race. Each time you press the button you can adjust the timer by one-minute increments for up to a 10-minute countdown timer. When you adjust the rotating bezel back to its default middle position, it resets the chronograph back to its main function.

This COSC certified Swiss chronometer is the self-winding caliber 4161 automatic movement beats at 28,800 vph and is completely manufactured by Rolex. This movement features the Rolex antimagnetic blue Parachrom hairspring. After receiving a COSC certified chronometer certification, the movement the goes through a thorough in-house chronometric testing once installed into a watch case. Once the watch achieves a precision of -2/+2 seconds per day in the case, it gets a Rolex Superlative Chronometer designation. Even with all these mechanical features, the 31 jewel caliber 4161 movement holds its power for 72 hours.

Rolex Sky-Dweller vs. Rolex GMT-Master II: Best Travel Watch?

When you think of dual time zone Rolex watches, you probably think of the GMT-Master II and the Explorer II. These mechanically identical Rolexes use a 24-hour hand to track a second time zone. The primary difference lies in their bezels: the GMT-Master II’s rotating 24-hour bezel allows for tracking of a third time zone. This is not the case with the Explorer II, nor with the Rolex Sky-Dweller . Unlike the GMT-Master II or Explorer II, the Sky-Dweller displays a second time zone via a rotating 24-hour ring on the dial. It also has an annual calendar complication, making it Rolex’s most complicated watch. How does the Rolex Sky-Dweller – a new-age mechanical outlier with elegant styling – compare to the GMT-Master II – Rolex’s tried-and-true sports watch with mid-century roots? Which dual time zone Rolex is the better travel companion?

Rolex Sky-Dweller

The Sky-Dweller is a unique watch. At 42mm in diameter, 51m lug-to-lug, and 14mm thick, it’s not for the faint of wrist. Much of this size comes from the caliber 9002 and accompanying dial space required to read out its complications. Around the outermost perimeter of the dial, a minutes track is interrupted not by hour indices, but “Saros” annual calendar windows. The 12 hour indices are paired with windows corresponding to each month (1 for Jan, 2 for Feb, etc.). At any given time, eleven of these windows are white, while one is red: demarcating the current month. This splash of red matches the arrow above the 24-hour timezone ring. The off-center ring is the defining characteristic of the Sky-Dweller: a unique way of showing its second time zone. At 3 o’clock, we see a date window magnified by a cyclops lens .

From a distance, you might mistake the Sky-Dweller for a Day-Date. They both have Rolex’s signature polished fluted bezel. However, unlike the Day-Date (or Datejust), the Sky-Dweller’s fluted bezel has a mechanical purpose. To set the month, date, local time, and reference time, you have to rotate the bezel between four fixed positions. Rolex calls this their Ring Command system, appearing only on the Sky-Dweller and Yacht-Master II . This is a quirky mechanism; not everyone wants to fiddle with their watch this much. That said, enthusiasts are more than happy to. 

Rolex GMT-Master II

Image Source: watchesbytimepiece.com

The Rolex GMT-Master II has the same general design as its predecessor from 1954 . Since then, there’s been one major development: the GMT-Master II has an independently-adjustable local hour hand, allowing for tracking of three time zones (and easier setting). Compared to the Sky-Dweller, the GMT-Master II is very straightforward. You have your local time, 24-hour time, and a rotating 24-hour bezel. This is the GMT watch that all other GMT watches emulate: dual time zone functionality in its purest form. The GMT-Master’s utilitarian philosophy extends to its build and case design. At 40mm in diameter, 48m lug-to-lug, and 12mm thick, the GMT-Master II is a bit more svelte than the Sky-Dweller, despite presenting as robust and somewhat chunky thanks to its Maxi case (2005 - today). Like all mid-century Rolexes, this is a tool watch that’s built to last: no frills, everything in its place. 

Final Thoughts

Image Source: facebook.com

The Sky-Dweller and GMT-Master II share a lot of characteristics: dual time zone functionality, cyclops date windows, and 100 meters of water resistance, to name a few. However, these are fundamentally different watches in their design philosophy, mechanics, and user experience. The GMT-Master II is a purpose-built tool watch; it tells two (or three) time zones, and will continue to do so past your lifetime. It’s easy to set, easy to read, and has nearly 70 years of field testing under its belt. The Sky-Dweller is a young, stylized, complicated watch that appeals to a smaller enthusiast demographic. Its fluted Ring Command bezel and annual calendar are in direct opposition to the GMT-Master II’s straightforward identity. Which is the better travel companion? That all depends on the wearer. Which one do you like more? Do you care about the annual calendar? Do you want a tool watch? A fluted bezel? These watches are so different that it’s hard to imagine someone being stuck between them. In all likelihood, one of them appeals more to you than the other. Which one do you choose?

Rolex Sky-Dweller 336934 Ultimate Buying Guide

Among Rolex’s luxury watch collections sits the Sky-Dweller, a distinctive model launched in 2012. Designed with world travelers in mind, the Sky-Dweller provides both stylish looks and intelligent functions. Rolex has continued innovating within the Sky-Dweller line, blending precision timekeeping with useful complications. 

The newest iteration comes as the 2023 Rolex Sky-Dweller Ref. 336934 , encased in a 42mm case of Oystersteel and white Rolesor gold. Signature elements like the fluted two-way Ring Command bezel and opulent dial colors remain, while technical upgrades also emerge. Read on to discover what sets this contemporary Rolex release apart as a global citizen’s watch built for life on-the-go. From dual time zones to an annual calendar, explore the Sky-Dweller’s capacities and see why it is in a class of its own even among Rolex’s storied catalog.

Key Feature and Design Details

The newest reference 336934 contains all the trademark styling and functionality expected from the Sky-Dweller line. The 42mm case dimensions remain unchanged, with the steel and white gold offering a heft befitting the model’s worldly caliber. 

Notable is the bidirectional Ring Command bezel , rendered in white gold with the collection’s signature fluted etching. This ingenious interface allows all-access control for setting the Sky-Dweller’s functions, from the dual time zones to annual calendar displays. Just rotate the bezel to toggle through the settings, enabling quick adjustments while traveling. 

New dial colors also emerge on the Ref. 336934, like eye-catching mint green and a sleek bright black, joining previous options of icy blue and placid white. Signature Chromalight display ensures legibility in all conditions. And behind all these visuals, the Rolex 9002 calibre movement drives the Sky-Dweller’s capabilities, Rolex’s Parachrom hairspring, and Paraflex shock protection further enhancing accuracy and resistance to disruption. 

Functions and Usability

As Rolex’s most complicated model accessible to the public, the Sky-Dweller boasts an array of functions tailor-made for globetrotting. At the watch’s heart lies the calibre 9002 movement, self-winding for perpetual functionality and boasting an approx. 72-hour power reserve. The paramagnetic Parachrom hairspring components alongside high-performance Paraflex shock absorbers also make the movement highly precise and resistant to disruption.

Augmenting the central hours-minutes-seconds hands is an off-center rotating disc displaying 24 reference cities. This dual-time function allows the wearer to easily reference home time or any other chosen time zone no matter one’s location around the world. Setting this reference time and aligning it to the main dial is achieved via the Ring Command bezel as part of Rolex’s intuitive interface. 

But what truly distinguishes the Rolex Sky-Dweller collection is the annual calendar feature, eliminating the need to continually adjust for short and long months. By tracking 30 and 31-day increments automatically, it requires only one manual date adjustment per year. The month itself is read clearly through 12 rectangular windows arrayed around the circumference of the dial. A cyclops lens date window is also visible at the three o’clock marker.

Boasting robust construction alongside intelligent complications, the Rolex Sky-Dweller Reference 326934 represents a foremost globetrotting watch. Its Twinlock waterproof architecture meeting a 100-meter depth rating pairs well with a glare-proof sapphire crystal protecting the dial and uniformly bright Chromalight display. 

Signature Rolex refinements like the fluted bezel and supple Jubilee bracelet retain luxury pedigree while the annual calendar and GMT complication powered by Rolex’s in-house movement prove practical anywhere one may roam. For frequent travelers who mandate flawless style and peerless function in equal measure, the latest Sky-Dweller iteration upholds its trajectory as one of the world’s great adventure companions. 

Unique Characteristics

The 2023 Sky-Dweller Ref. 336934 debuts distinguishable new colors like mint green and bright black for the lacquered dial, contrasting beautifully with the fluted white gold bezel and stainless-steel case. This refreshed palette demonstrates Rolex’s knack for styling evolutions even amid an already iconic watch. 

And displayed against the dark dial backdrop, the Sky-Dweller’s innovative complications shine through in legible fashion. An inverted red triangle points clearly to the chosen reference city time along a rotating 24-hour disc, while red rectangles indicate the current month through 12 distinct window apertures. The black dial maximizes this functionality’s visibility, just as the mint green variation provides a more subtle contrast. 

While functionality defines the Sky-Dweller’s essence, several styling touches still grant the watch its revered aesthetic polish. The signature fluted bezel immediately aligns the watch with luxury expectations before any complications come into play. Hour markers evoke a classical elegance, framing the metallic hands and dot markings that populate the dial with information. 

And the watch’s sleek shape from lug to bracelet link retains continuity from previous Sky-Dweller generations, upholding Rolex’s careful refinement process across decades. This ensures comfort and proportional balance when choosing the three-link Oyster or five-link Jubilee bracelet pairings. Understated day or night, the Sky-Dweller cuts a fine figure even without its globe-trotting toolset on display. 

Eminently capable yet undeniably elegant, the 2023 Sky-Dweller Ref. 336934 epitomizes Rolex’s guiding ethos as a pragmatic yet opulent creation. For globetrotters unwilling to compromise either functionality or style, its rare hybrid merits shine through. 

Positioning and Availability 

As part of Rolex’s 2023 watch catalog , the latest iteration of the Sky-Dweller upholds the company’s unrelenting pursuit of excellence and innovation decade after decade. With a retail price between $15,650 to $15,900 USD, it manages to balance functionality against cost compared to even more complicated offerings labeled under the Rolex banner. 

Combined with Rolex’s reputation for uncompromising quality , the Ref. 336934 Sky-Dweller represents one of the smartest luxury sports watch values on the market today. Its versatile styling allows both understated cool or more outright professional flair depending on the bracelet and dial combination selected. And unrelenting global demand for Rolex watches ensures strong residual value should one ever consider parting ways. 

But perhaps most remarkable is how the Sky-Dweller demonstrates what the manufacturer is capable of when pushing boundaries. Rather than resting on laurels, Rolex continues carving new niches that expand conceptions of what a wristwatch can achieve. For Rolex Ref. 336934, that means melding precision reliability with intelligent displays suited ideally for world travelers. 

At once pragmatic and prestigious, Rolex’s latest Sky-Dweller iteration upholds the company’s track record of cult classics blended from equal parts engineering prowess and design savvy. A 21st-century watch balances beautifully between past heritage and future innovation. 

Final Thoughts 

With its 2023 Sky-Dweller 336934 model, Rolex affirms its leadership in crafting the ultimate globetrotter’s watches, deftly calibrated for both professional travelers and high-flying jet setters. Superlative design meets intelligent functionality through intuitive interfaces like the Ring Command bezel and Chromalite hour markers. Distinct dial colors inject fresh styling flair while retaining the signature traits of an eminent lineage. Everyday reliability secured by the manufacturer’s patented movements and hardened metals makes enjoying these multifaceted capacities effortless. 

Few timepieces so aptly navigate complexity against accessibility as Rolex’s unique luxury tool watch, manifesting generations of watchmaking refinements into a showcase formed to suit modern life’s boundless joys and challenges. Elevating human journeys has long pulsed at the brand’s core, a motive once again reaffirmed by the handsome and capable Sky-Dweller Ref. 336934. With vision cast perpetually forward but roots still firmly in excellent foundations, Rolex proves once more why its celebrated crown logo endures as the inevitable worldwide companion for life’s exciting odyssey.

OYSTER PERPETUAL SKY-DWELLER

TO THE ULTIMATE AND BEYOND

With its two time zones and annual Saros calendar, the Sky-Dweller is an elegant and trusted companion for world travellers. The range has been updated with numerous enhancements illustrating the role that excellence plays even in the tiniest details.

A WEALTH OF EXPERTISE   An elegant watch for frequent travellers, the Sky-Dweller displays the time in two time zones simultaneously and has an annual calendar. The reference time is displayed in 24-hour format via an off-centre disc, and local time is read using the conventional centre hands. The annual calendar, named Saros, automatically differentiates between 30- and 31-day months. It is operated by a patented mechanism and stands out for its innovative display: the months of the year are shown in 12 apertures around the circumference of the dial, beyond the index hour marker – the current month being shown in red. The instantaneous date change is linked to the local time. The Sky-Dweller includes the Ring Command system, an interface between the rotatable bezel, winding crown and movement that allows the wearer to select and set the timepiece’s functions one by one, easily, quickly and securely.

ROLESOR, A MARRIAGE OF GOLD AND STEEL Rolesor, the combination of gold and Oystersteel on a Rolex watch, has been a signature feature of the brand since 1933, when the name was registered. It is a meeting of two metals: one, noble and precious, attractive for its lustre and stability; the other, highly resistant to corrosion, assuring strength and reliability. All of these qualities mirror the elegance and performance that come together in a Rolex watch. On the new Sky-Dweller offered in the white Rolesor version, the bezel is in white gold; the winding crown, middle case, case back and bracelet are in Oystersteel. 

THE OYSTER CASE, SYMBOL OF WATERPROOFNESS  A paragon of robustness and elegance, the 42 mm Oyster case of the new-generation Sky-Dweller is guaranteed waterproof to a depth of 100 metres (330 feet). The middle case of the versions presented is crafted from a solid block of Oystersteel, or 18 ct white or Everose gold. Its case back, edged with fine fluting, is hermetically screwed down with a special tool that allows only Rolex watchmakers to access the movement. The Twinlock winding crown, fitted with a double waterproofness system, screws down securely against the case. The crystal, which features a Cyclops lens at 3 o’clock for easy reading of the date, is made of virtually scratchproof sapphire and benefits from an anti-reflective coating. The waterproof Oyster case provides optimal protection for the movement it houses.

PERPETUAL CALIBRE 9002 The new-generation Sky-Dweller is equipped with calibre 9002, unveiled this year. A distillation of technology, this self-winding mechanical movement – a derivation of calibre 9001, one of the most complex movements designed by Rolex and which had driven the model since its launch in 2012 – delivers outstanding performance in terms of precision, power reserve, convenience and reliability. Calibre 9002 incorporates the patented Chronergy escapement, which combines high energy efficiency with great dependability. Made of nickel- phosphorus, this escapement is resistant to strong magnetic fields. The movement is fitted with a blue Parachrom hairspring, manufactured by Rolex in a paramagnetic alloy. The hairspring offers great stability in the face of temperature variations as well as high resistance to shocks. It is equipped with a Rolex overcoil, ensuring the calibre’s regularity in any position. The oscillator is mounted on the Rolex-designed, patented high-performance Paraflex shock absorbers, increasing the movement’s shock resistance. The oscillating weight is fitted with an optimized ball bearing. Calibre 9002 is equipped with a self-winding system via a Perpetual rotor. Thanks to its barrel architecture and the escapement’s superior efficiency, the power reserve of calibre 9002 extends to approximately 72 hours.

OYSTERFLEX AND OYSTER BRACELETS Among the versions of the new-generation Sky- Dweller presented this year, the watch in 18 ct white gold sporting a bright black dial is fitted on an Oysterflex bracelet. Developed by Rolex and patented, this innovative bracelet is made up of two flexible, curved metal blades – one for each of the sections – overmoulded with high-performance black elastomer. The new white Rolesor version (combining Oystersteel and white gold), adorned with a mint green dial, as well as the 18 ct Everose gold watch, with a blue-green dial, are fitted on an Oyster bracelet. Developed at the end of the 1930s, this three-piece link bracelet remains the most universal in the Oyster Perpetual collection and is known for its robustness. The Oysterflex bracelet and the Oyster bracelet of the Sky-Dweller are both equipped with a folding Oysterclasp. The Oysterflex bracelet is furnished with the Rolex Glidelock extension system. Developed by the brand and patented, this inventive mechanism with a rack located under the clasp cover enables fine adjustment of the bracelet length, without the need for tools. The Rolex Glidelock on the Oysterflex bracelet has six notches of approximately 2.5 mm, allowing the length of the bracelet to be adjusted easily up to some 15 mm. For its part, the Oyster bracelet of the Sky-Dweller features the Easylink comfort extension link, developed by the brand, which allows the wearer to easily increase the bracelet length by approximately 5 mm. On the version in 18 ct Everose gold, the bracelet also includes patented ceramic inserts – designed by Rolex – inside the links to enhance its flexibility on the wrist and its longevity. 

SUPERLATIVE CHRONOMETER CERTIFICATION Like all Rolex watches, the Oyster Perpetual Sky-Dweller is covered by the Superlative Chronometer certification redefined by Rolex in 2015. This designation testifies that every watch leaving the brand’s workshops has successfully undergone a series of tests conducted by Rolex in its own laboratories according to its own criteria, following the official certification of the movements by the Swiss Official Chronometer Testing Institute (COSC). The in-house certification tests apply to the fully assembled watch, after casing the movement, guaranteeing superlative performance on the wrist in terms of precision, power reserve, waterproofness and self-winding. The precision of a Rolex Superlative Chronometer is of the order of −2 /+2 seconds per day – the rate deviation tolerated by the brand for a finished watch is significantly smaller than that accepted by COSC for official certification of the movement alone. The Superlative Chronometer status is symbolized by the green seal that comes with every Rolex watch and is coupled with an international five-year guarantee.

The oysterflex bracelet, highly resistant and durable.

The Sky-Dweller’s new Oysterflex bracelet, developed by Rolex and patented, offers a sporty alternative to metal bracelets. The bracelet attaches to the watch case and the Oysterclasp by a flexible titanium and nickel alloy metal blade.

The blade is overmoulded with high-performance black elastomer which is particularly resistant to environmental effects, very durable and perfectly inert for the wearer of the watch. For enhanced comfort, the inside of the Oysterflex bracelet is equipped with a patented longitudinal cushion system that stabilizes the watch on the wrist and fitted with an 18 kt white gold Oysterclasp. It also features the Rolex Glidelock extension system, designed by the brand and patented. This inventive toothed mechanism, integrated beneath the clasp, allows fine adjustment of the bracelet length by some 15 mm in increments of approximately 2.5 mm, without the use of tools.

18 kt white gold

Commitment to excellence

By operating its own exclusive foundry, Rolex has the unrivalled ability to cast the highest quality 18 kt gold alloys. According to the proportion of silver, copper, platinum or palladium added, different types of 18 kt gold are obtained: yellow, pink or white.

They are made with only the purest metals and meticulously inspected in an in-house laboratory with state-of-the-art equipment, before the gold is formed and shaped with the same painstaking attention to quality. Rolex's commitment to excellence begins at the source.

Bright black dial

A striking characteristic.

A fixed inverted red triangle on the dial points to the chosen reference time – the time at home or at the traveller’s usual workplace – on the off-centre 24-hour disc. At a glance, this 24-hour display clearly distinguishes daytime hours from night-time hours in the other time zone.

A deep red rectangle in one of the 12 windows around the dial indicates the current month, a striking characteristic of the Saros annual calendar. This ingenious mechanism simplifies life for the wearer of the watch, who no longer needs to think about adjusting the date at the end of a 30-day month. The annual calendar displays the correct date through the year. Only one adjustment is needed – on 1 March (February having only 28 or 29 days). The date is connected to local time and automatically changes according to the traveller’s local time zone.

The Fluted Bezel

A rolex signature.

The Rolex fluted bezel is a mark of distinction. Originally, the fluting of the Oyster bezel had a functional purpose: it served to screw the bezel onto the case, helping to ensure the waterproofness of the watch.

It was therefore identical to the fluting on the case back, which was also screwed onto the case for waterproofness, using specific Rolex tools. Over time, the fluting became an aesthetic element, a genuine Rolex signature feature. Today the fluted bezel is a mark of distinction, always in gold. The Sky-Dweller is equipped with a mechanism of interaction between the rotatable bezel, the winding crown and the movement: the Ring Command system, which allows the user to select the watch's functions one-by-one and to set them easily, quickly and securely.
