Rolex has just unveiled a new and improved its top of the line dive watch, giving the Deepsea Sea-Dweller, including the version with the “D-Blue” graduated dial, a new-generation calibre and a redesigned case.

While the stainless steel case remains 44mm with a titanium case back – and the patented Ringlock construction for unparalleled pressure resistance – the new Deepsea is now fitted with a wider Oyster bracelet and a resized Oysterlock spring-loaded safety clasp, giving the large case a bracelet that is suitably substantial.

And for the first time, the Deepsea is equipped with the calibre 3235 – the same movement found in the Sea-Dweller 4000 ref. 126600 launched last year. It is equipped with a Chronergy escapement and Parachrom hairspring. In contrast, the original Deepsea was powered by the calibre 3135, which lacked the various technology bells and whistles.

All else otherwise remains unchanged. The “D-Blue” version features the same dial with a dark blue to black graduated finish, a reference to the pitch black depths of the ocean.

As before, the new Deepsea boasts extreme water resistance up to 12,800ft, or 3900m. And to that end, the watch features bright blue Chromalight luminescence for optimal visibility in darkness, the patented Ringlock System, the helium escape valve as well as the “Triplock” winding crown.

Price and availability 

The new Deepsea (ref. 126660) with “D-Blue” dial costs US$12,550, and with the all-black dial it is US$12,250.
