The black dial of the Sea-Dweller has the large hands and indices reserved for Rolex professional models. The dial bears the name Sea-Dweller in red, a reference to the first model. The innovative Chromalight display on the dial pushes back the boundaries of visibility in dark environments. Its distinctive blue glow lasts up to eight hours with a uniform luminosity, practically twice as long as that of standard luminescent materials.
Further, the new Sea-Dweller’s solid-link Oyster bracelet in 904L steel is fitted with an Oysterlock safety clasp that prevents accidental opening. A double extension system allows adjustments to be made without the use of tools, so that the watch can be worn comfortably over a diving suit up to 7 mm thick. The Fliplock extension link extends the bracelet by 26 mm, while the Rolex Glidelock system allows fine adjustment of the bracelet length in 2 mm increments for a total of approximately 20 mm.
The Sea-Dweller is equipped with calibre 3235, a new-generation movement entirely developed and manufactured by Rolex. This self-winding mechanical movement is at the forefront of the art of watchmaking. A consummate demonstration of Rolex technology, with 14 patents, it offers fundamental gains in terms of precision, power reserve, resistance to shocks and magnetic fields, and also reliability.
