All you need to know about the Rolex Sea-Dweller 43mm Ref. 126600 – Why it is like it is? (REVIEW)

Sure, we expected ‘something’ to happen to the Sea-Dweller. However what Rolex actually decided upon, came as a complete surprise and was regarded by some as controversial. It was maybe not what long-time Rolex collectors were hopping for, however the new Rolex Sea-Dweller 43mm Ref. 126600 has been one of the main talking pieces of Baselworld 2017. Just like the Ceramic / Steel Daytona made the headlines in 2016. The main novelty of Rolex for 2017 might be less easy to understand than for instance the star of last year’s novelties. That’s why we’re going in-depth (Monochrome style) and tell you all possible explanations about the new Rolex Sea-Dweller 43mm Ref. 126600, a watch that maybe needs more than just a quick glance to be fully apprehended.

Rolex Sea-Dweller 43mm 126600 - Baselworld 2017 Review

When Rolex does something, there’s always a good reason behind it. Whether you like the brand or not, you cannot say they do a half job – even if on very rare occasions, they have to correct one or two details (see the 2016 Explorer I.) Yet, if one evolution or one feature is added to a watch, the motivation is simple: make it better or make it more coherent. With the new Rolex Sea-Dweller 43mm Ref. 126600, some people (actually quite a lot) have been surprised by several features; the larger diameter and the cyclops over the date window being the main objects of the controversy. Of course we asked the question, and of course Rolex had a clear explanation for “everything new” in this Sea-Dweller 126600. Here’s what we heard… plus of course our take on things!

50 Years of Innovation and Constant Evolution

The Sea-Dweller’s history is linked to the history of dive watches and of scuba diving on its own. After WWII, diving has become a popular sport, or recreational activity, and dive watches were being developed. Dive watches became available for both military, professionals and civilian recreational divers. The Submariner ref. 6200 was the world’s first commercially produced dive watch, which was released in 1954, with a 100m water resistance (later 200m and 300m). In the early 1960s experiments on saturated diving had started and immediately the need for watches with greater water resistance emerged. At that time, the Submariner ref. 5513 could withstand 200 meters of depth, but the goal of Rolex was to triple the depth rating.

The First version of the Sea-Dweller, 1967

Experiments were carried out by Rolex in collaboration with COMEX (a professional diver’s company), for the creation of a feature that would later become the hallmark of the Sea-Dweller: the helium escape valve. It was first introduced on the Submariner ref. 5514, and shortly after, in 1967, Rolex introduced the Sea-Dweller ref. 1665. This was actually the first Sea-Dweller and became the recognizable diver watch with helium escape valve. The early models from 1967 (production estimated to approx. 100 pieces) were very similar to the Submariner 5514 COMEX that was retrofitted with helium escape valve. Characteristics are a “double red” dial with “Submariner 2000” and no “patent pending” case back (as Rolex had filed for patent, but had not yet received the patent on the helium valve). Very rare examples can be seen in the “single red” version. These prototypes (with estimated production of 4 watches) were rated for 500m.

Several evolutions will be seen during the production of the Sea-Dweller. The “Double Red” Sea-Dweller (with the “Submariner 2000” mention too) was produced from 1971 to 1977, still with a 2000ft / 610m water resistance and “patent pending” caseback. In 1977, the Rolex Sea-Dweller evolves again, becoming the “great white”. No red indication anymore, no mention of “Submariner 2000” anymore, and this was done to better differentiate between the Submariner and the Sea-Dweller watches. By 1978, and alongside the ref. 1665, Rolex introduced the ref. 16660 Sea-Dweller fitted with a sapphire crystal, a bigger helium release valve and an upgraded depth rating to 4,000 feet or 1,220 metres. Finally, in 1988, Rolex launched the Ref. 16600, with the modern calibre 3135, solid end-links on the bracelet and a glossy dial. The ref. 16600 was discontinued twenty years later, in 2008, and replaced by the Sea-Dweller Deepsea.

In 2008, Rolex stopped the production of the Sea-Dweller 4000ft to move to greater water resistance and a watch with an even stronger professional orientation: the Sea-Dweller Deepsea with a 12,000 feet or 3,900 metres water resistance, a 44mm case and of course the helium escape valve. While technically more advanced and more efficient, this watch couldn’t replace the SD in the heart of collectors and this why the Sea-Dweller 4000 came back in production in 2014 as ref. 116600. The now discontinued ref. 116600 has the same 1,220 meters water resistance, the helium valve and features a slimmer case, a ceramic bezel and a Glidelock bracelet, and of course white text on the black dial, no cyclops and a 40mm case.

The 43mm Diameter of the Rolex Sea-Dweller Ref. 126600

The first and probably main topic of discussion about this new Rolex Sea-Dweller Ref. 126600 is about its diameter, a large diameter of 43mm to be precise. It is not the first time that Rolex does a large watch (see the 44mm Deepsea), but usually, there’s a technical reason behind an increased case. For decades, the standard diameter of sports watches at Rolex has been 40mm, a quite reasonable and wearable size, suitable for most. You can find this size on the Submariner, on the GMT-Master II, on the Yacht-Master, and… on the previous Sea-Dweller ref. 116600.

Rolex Sea-Dweller 43mm 126600 - Baselworld 2017 Review

The Sea-Dweller has always been a bit in the shadow of the Submariner. Maybe that’s because both models are not only visually but also size-wise extremely close. With the 2014 edition, there might have been a “differentiation issue”, because the SD4K (Sea-Dweller 4,000ft) is a bit thicker than the Submariner, but it has more elegant lugs. The only difference is the absence of cyclops, a slightly more precise scale on the bezel and the different (higher) depth-rate with helium escape valve (1,220m vs. 300m). Still, in modern days, this water-resistance factor makes less sense than in the 1960s, as few of us are really using a Rolex as a professional piece of equipment to dive (affordable and very reliable diving computers are widely used). You might have guessed the point of the 43mm diameter: differentiation! It will be the answer for certain markets, where people prefer larger watches (US mainly), and it adds some emphasize on the robust tool-watch look.

In order to create a real contrast between the these dive watches that are the Submariner and the Sea-Dweller, Rolex chose to make the latter larger – it is a deliberate choice, motivated and well-thought (Rolex is not used to do things in a rush). Like it or not, but the mild success of the previous 40mm Ref. 116600 required a correction. Thus, the new Rolex Sea-Dweller Ref. 126600 becomes larger, not only in diameter but the whole watch has grown: larger case of course, larger bracelet (22mm instead of 20mm), larger bezel, larger indexes, larger hands, larger buckle (correcting one of the flaws of the 116600, with a too thin buckle). Overall, Rolex wanted to keep proportions intact and to stick to the look of the Sea-Dweller, even if larger.

Technically, the Rolex Sea-Dweller Ref. 126600 shows no evolution: same 1,220m / 4,000ft water resistant, still the iconic helium escape valve on the left side of the case (the hallmark of the model), still the 60-minute scale on the ceramic bezel, with one-minute markers from 0 to 60 (not on the Submariner), same display, same Triplock crown, same prominent caseback, same buckle with long diving extension, same overall quality and feeling of having a proper “tool” on the wrist.

The Rolex Sea-Dweller Ref. 126600 on a small wrist (below 17cm / 6.7 inches)

Talking about “on the wrist“… how does this watch look in its natural habitat? Well, to be honest, I have small wrists and I usually love smaller watches. I’m a regular wearer of 40mm Rolex watches or 41mm Tudor dive watches, and they are, to me, showing perfect proportions, well balanced in-between a sporty approach and a certain elegance that you want when wearing a luxury watch. Yet, the Sea-Dweller 126600 has to be regarded differently, as a proper tool. So the bigger case does not disturb me that much. Moreover, I’ve been pleasantly surprised by the looks on the wrist (see the photo above… It’s large but not overly large).

The case has been redesigned and the lugs are shorter and more curved, thus suitable for smaller wrists too. Of course, people with 19cm / 7.5 inches or plus wrists will be even more pleased. Then, there’s the balance on the wrist. Some found the previous 40mm Sea-Dweller slightly unbalanced on the wrist, because it was ‘only’ 40mm and rather thick; too thick for such a diameter, which made this watch quite wobbly when worn. The new 43mm feels more stable. Surprising, but it really does. In the end, the 43mm diameter will have supporters and critics, but you can’t denied two factors: a clear differentiation with the Submariner and more comfort on the wrist.

The Single Red Dial

Things are changing at Rolex. I dare to say it, but this simple red line of text on the dial is an important move for the brand. What would have been insignificant for most other brands, is for Rolex quite a revolution (relatively speaking of course…) Jokes apart, the brand has evolved in the past 2 / 3 years, with the addition of a rubber bracelet, a rather unexpected dial on the Air King (and yes, it is a success in stores) or the unavowed vintage-inspired Daytona Steel / Ceramic. And that “Single Red” feature is in the same vein, a look back at origins.

Without saying that Rolex is about to introduce a Heritage Collection (no spoiler alert…), it seems that the “crown” wants to please some collectors and to reassure them with small but iconic details, such as panda dials or this red model name. This makes even more sense on this Rolex Sea-Dweller Ref. 126600, launched exactly 50 years after the introduction of the model in 1967. Rolex, without loosing its “always look forward” and innovative spirit, could rely more often on such small details to create a hype on certain models. This “single red” dial must be the most appreciated feature in this new version.

The Cyclops on the Date Window

Rolex Sea-Dweller 43mm 126600 - Baselworld 2017 Review

Now comes the other feature that created discussions about the Sea-Dweller Ref. 126600: the cyclops over the date window. This was clearly unexpected and this somehow broke the idea behind the model, which has always been without the magnifying cyclops. Still, its apparition has to be explained, and is justified by Rolex and its DNA.

If you take a close look at the Rolex collection, you’ll notice that every single watch in the collection that features a date window comes with a cyclops (Datejust, Day-Date, Sky-Dweller, Submariner Date, Explorer II, GMT-Master II, Yacht-Master 40). Now there’s only one exception: the Sea-Dweller Deepsea. The date magnifier is entirely part of the brand’s DNA. It has been absent on the Sea-Dweller for all these years, however not for aesthetic reasons, but for technical reasons. Wether we look at the vintage versions with Plexiglas or more modern editions with sapphire, the 120-bar pressure that the Sea-Dweller had to withstand was so high that the cyclops was simply breaking from the crystal.

Rolex Sea-Dweller 43mm 126600 - Baselworld 2017 Review

Now, you have to think with Rolex neurons… Which means that “if technically we are able to do it, there’s no reason not to do it“. Plus, as said, the cyclops is an iconic feature of Rolex watches with date. And now that Rolex achieved to find a solution (no detailed explanations given by the brand, merely this statement) to have a cyclops that can resist the pressure endured by the Sea-Dweller, there was no reason anymore for the brand not to glue it on the SD’s crystal. It might be quite disappointing for some collectors, however when you look at things through the eyes of the “crown”, it simply makes sense. (note: the Deepsea is now the only date-equipped model without cyclops, for 2 reasons – the immense pressure it has to deal with makes impossible to have this feature, plus the crystal is not flat but domed). Now the question like/dislike is personal and final clients will be the only judges of the relevance of the added cyclops.

The New Generation of Rolex Movement (Calibre 3235)

Here’s the part that should normally create unanimity: the Calibre 3235. The Rolex Sea-Dweller Ref. 126600 will be the first watch of the professional collection to benefit from the new generation of movements, the 32xx introduced first on the 2015 Day-Date and later used on the 2016 Datejust. From now on, it seems that every new Rolex watch (entirely new ones, not just new dials…) will benefit from this upgrade. And honestly, as good as can be the older 31xx movements, this new-gen is simply better in all aspects.

Rolex Sea-Dweller 43mm 126600 - Baselworld 2017 Review

Compared to the previous series of movements, the Calibre 3235 has 90% new parts: new barrel, new gear train, new escapement, new bridges and plates, new rotor, new automatic winding system. Not only the parts are new but most of them come with modern technologies, with a clear efficiency goal.

The 3235 has 70h power reserve, thanks to a more efficient escapement (dubbed Chronergy, which increases the efficiency of the escapement by 15%, and contributes to almost half of the gain in power reserve), an optimized gear train, with high-performance lubricants with a longer useful life and greater stability over time (less friction, less wear, less energy consumption), a high-capacity barrel (with a longer main-spring without changing the size of the barrel), blue Parachrom hairspring (resistant to magnetic fields), in-house high-performance Paraflex shock absorbers, large balance wheel with variable inertia and finally new self-winding module, for a more rapid winding of the new high-capacity mainspring.

The overall finishing has been improved, with bevelled bridges, circular brushing, jewels in gold chatons and other details that make this movement better looking than the previous 3135. Of course, as all Rolex movements, the Calibre 3235 is a Superlative Chronometer (-2 / +2 seconds per day) and comes with a 5-year warranty.

Conclusion

Rolex Sea-Dweller 43mm 126600 - Baselworld 2017 Review

This new Rolex Sea-Dweller Ref. 126600 creates some debates, brings some questions and shows a stronger evolution than what we’ve seen in the past. And if you want to know, this is a very good point. I guess that we (journalists, collectors, watch lovers, owners) might have had a rather narrow, conservative, expectation from the brand. This watch, alongside the provocative Air-King or the much-hyped Daytona Steel / Ceramic, shows a new strategy – nothing brutal, still relying on the DNA of the brand, but more in line with expectation of the markets.

In fact, I think Rolex will benefit from a bit of controversy, instead of doing products that most will like, but few will love or hate. We have to remember that the purchase of a €10k watch is mainly driven by emotions and with the Sea-Dweller Ref. 126600, Rolex comes back to more emotional, yet more segmented products. The SD has always been rather niche in the collection and for such a product, most decisions the brand made about this 2017 edition seem quite coherent.

And to answer the unavoidable question: do you like it? Well, I would say that my first reaction has been on the negative side, however now, after a few days, I have to admit that it is growing on me. I guess that Rolex might have made the right decision here, with a more toolish, more professional style.
