In the years that Rolex has dominated the market, we have seen them have their fair share of changes and revolutions to further cement the brand as one of the best to ever do it.
So much traction and publicity surrounds Rolex that every minor change they make to their lineup winds up being a major headline. One of the most recent big changes is the cancellation of the Submariner 40mm and the rise of the 41mm.
The Submariner series is a model that has continued to disrupt the entire industry. Part of the reason Rolex has reigned supreme for so long is because of the iconic legacy that this watch holds.
Since its release, the Submariner has always been sized at 40mm or less, which is why it was such a major headline when Rolex suddenly enlarged the Oyster case to 41mm and canceled the production of the 40mm altogether.
But what other features were changed besides the size, and why did Rolex feel like it was necessary to make these changes? Today, we will be comparing the 40mm to the 41mm and examining what stands out between the two and how one could potentially outperform the other.
40mm

The History of the Submariner is one of great importance. In a way, the Submariner is responsible for the reputation of Rolex itself. The cultural relevance that this piece holds is, quite frankly, too massive to capture fully.
Just know that everything that has come after the original Submariner has—in some way—been shaped by the iconic design.
When Rolex created their first diver in 1953, it wasn’t until six years later, in 1959, that the Submariner case was increased to 40mm, and the crown guards were added.
Over time, the design stuck, and with how famous Rolex is for hardly ever tampering with their designs, the Submariner still stood out as one of the least altered models in the entire catalog.
The Reference 6204 is generally accepted as the debut Submariner. Upon its debut, it drew instant comparisons to the Blancpain Fifty Fathoms, which is healthily considered one of if not the first dive watch ever created.
Since it shared many of the same features as the Fifty Fathoms (jet black dial, same hour and minute hands, and an inverted triangle), it was difficult to tear away and make an authentic name for itself. But Rolex eventually revealed a trick up its sleeve that perhaps no one saw coming.
The Oyster case was equipped with a specific winding crown system that came with a gasket that could screw into a tube inside of the case itself.
This proved to offer a tremendous level of water protection that outshined the competition, eventually causing the Submariner to become the first-ever diver to be able to outlast 100 meters of water pressure.
The aesthetical prowess of the Submariner cannot be understated either. It has a sophisticated nature while also being subtle enough to style with casual wear.
The more models that were produced, the more seriously the community viewed them until, eventually, after a decade of fine-tuning and perfecting, The Submariner finally settled down and seemed to be consistent with its design. In 1959, the ref. 5512 provided a solid foundation for all Submariner models going forward, and the design has been virtually consistent ever since.
The turn of the century found increased demand for a larger submariner, with some suggesting that 40mm was much too small for a modern sports model. It made sense. Watches of similar style were advancing in size.
This caused Rolex to take a step back and subtly refine the case of the 1166xx series. While still 40mm, the Super Case of the 1166xx had thicker lugs, crowns, and guards, which gave the impression of a more durable watch.
This caused a fair amount of controversy as some fans appreciated the thicker size, while some still longed for the classic design of past references.
It would take until 2020, however, until Rolex finally decided to make a significant change that proved to silence the controversy and please all of its buyers.
The 1266xx was released as the first-ever Submariner to exceed 40mm, declaring the end of an age and the start of something new and spectacular.
41mm

With softened elements that provide an increased sense of elegance, the new Submariner also keeps the angular design of past reference models, causing a perfect blend of new and old features to please both sides of the spectrum.
It captures more of a vintage feel, taking surprisingly short strides to separate itself from its predecessor, holding on to the older look much tighter than anyone expected.
The lugs are longer and slimmer, and the crown guards are significantly thinner, trimming the aesthetic down and supplying the watch with a much more tapered profile, so for the Submariner fans who perhaps thought that previous generations were too bulky, this new edition may prove to be ideal.
Other measurements have been changed aside from the case. For example, the bracelet has been increased from 20mm to 21mm.
There are now two crowns that appear on the dial, and the “Swiss Made” text that used to be on older models is now separated by the Rolex crown between the two words.
Perhaps the most innovative feature is the upgraded movement. For more than 30 years, the Submariner has been driven by the Cal. 3135, one of the most popular and finest mass-produced movements ever crafted.
Even so, Rolex decided it was time to retire the dated movement and focus their sights on something fresh. Now, the Submariner—and many other Rolex models—are powered by the Cal. 3235, which has revolutionized modern pieces, improving upon nearly everything within, making them more efficient and more precise.
The 41mm seeks only to improve, aiming to upgrade every aspect of the older models. It doesn’t try to be too much, not exactly flipping the original on its head, but doing just enough to make noticeable improvements.
Rolex has maintained the Submariner’s reputation through their innovative minds, evolving not only the Submariner but the majority of their pieces to fit the new demand of the market. It’s no wonder how they have a virtually flawless reputation.
40mm vs. 41mm—How to choose.
As of today, Rolex no longer sells the 40mm Submariner, though—in my opinion—there is no reason why anyone would realistically prefer the 40mm to the 41mm other than rarity value. The 41mm is simply the better alternative, as it improves virtually everything, leaving nothing more to be desired.
From a collector’s perspective, you may be eager to get your hands on one of the retired 40mm, but other than a few specific instances, I would have to wholeheartedly recommend the 41mm as the superior piece.
Conclusion
Rolex is a brand that constantly demands respect. Even though most would agree it took them much too long to upgrade the Submariner, the common consensus is that the new 41mm is one of the most spectacular watches they have ever produced.
For a brand to stay at the top for so long, it cannot be pushed around by the market; it has to adapt to change while making innovative decisions to propel publicity and get both new and old fans excited for improvements.
The Submariner did just that. Now, as it continues its reign as one of the top divers available, it’s only a matter of time before the next upgrade is needed because the luxury watch market is never silent, and when brands start getting too comfortable, they will undoubtedly miss out on the next big thing.
If I can leave you with any advice, it would be to trust Rolex. History has proven that they never get too comfortable, as they are always seeking to push the boundaries and meet the enviable shift in the market with their own shifts as well.
