Speaking of this year’s new Rolex products, Deepsea Sea-Dweller Ref.136660’s presence is very low, not only people rarely discuss it in the forum, and even the official does not write news materials for it. We also learn about its information from the quietly updated details page. It can be said that it is the most low-key new product of Rolex this year.

Unlike Air-king’s iterative product, which was upgraded from a 31-series movement to a 32-series movement, the Deepsea Sea-Dweller Ref.126660 released in 2018 has been equipped with a Cal.3235 movement. The new Deepsea Sea-Dweller in 2022 has not changed the movement model, and still uses the Cal.3235 movement. It is more based on the fine-tuning of the appearance. The following is a combination of the information released by the foreign media to upgrade the new product.

From the front, the most notable upgrade of the Deepsea Sea-Dweller is the calendar window. It has a larger display area, allowing the wearer to read the date clearly. We know that Rolex uses a convex lens calendar display window for both the Submariner and the Sea-Dweller. This design originated from the Datejust type and has now become one of the iconic elements of Rolex. However, among many Rolex diving watches, only the Deepsea Sea-Dweller does not have a convex lens calendar display window. The reason is that the convex lens calendar window is not formed in one piece, but is bonded by two pieces of sapphire glass through a special process. The waterproof rating of Deepsea Sea-Dweller is 3900 meters, and the pressure during deep diving is several times that of ordinary diving watches. Therefore, in order to ensure stability, Deepsea Sea-Dweller’s upgrade to the calendar window is only to increase the display area, rather than using a convex lens window.

The second upgrade of Ref.136660 is the bezel. The ceramic outer ring of the Deepsea Sea-Dweller has become more slender, which can enhance the refined feel of the watch to a certain extent. At the same time, the brand has also optimized the rotation mechanism of the outer ring, and the new product has a better rotating feel. The mirror is also one of the upgrade points. The sapphire mirror with reflective coating can effectively resist strong light refraction and make reading more clear.

The luminous effect has also been optimized. Early Rolex watches all used Super-LumiNova luminous, which is currently the most mainstream luminous material. However, Rolex watches, which were produced after 2008, stopped the use of Super-LumiNova and changed  to the brand-exclusive Chromalight luminous. Chromaligh has a longer glow time and a stable level of light. The new Deepsea Sea-Dweller Ref.136660 adopts the latest generation Chromaligh luminous solution, and its luminous duration and brightness are improved compared with the previous generation Chromaligh luminous.

Let’s talk about the changes to the bottom cover again. In the old Ref.126660, the black “ROLEX OYSTER DEEPSEA ♕ SEA-DWELLER 12800 ft = 3900 m” is surrounded by the edge of the titanium case back to indicate the series to which the watch belongs and its water resistance. In the bottom cover of the new Ref.136660, this material has an exclusive name: “RLX titanium alloy”.

However, with regard to Deepsea Sea-DwellerRef.136660, no real pictures have been seen so far, and more details about this product have yet to be further confirmed.
