D-Blue Dial
Commemorating James Cameron’s historic solo dive. From brilliant blue to bottomless black, its two-colour gradient dial celebrates one man’s journey to the deepest place on earth: the bottom of the Mariana Trench.
Ceramic Bezel and Luminescent Display
The 60-minute graduated, unidirectional rotatable bezel of the Rolex Deepsea enables divers to precisely and safely monitor their dive and decompression times. It is equipped with a patented black Cerachrom bezel insert manufactured by Rolex in a virtually scratchproof ceramic whose colour is unaffected by ultraviolet rays. The graduation is coated via PVD (Physical Vapour Deposition) with a thin layer of platinum. The dial features large Chromalight hour markers and hands, filled with luminescent material that emits a long-lasting blue glow for excellent legibility in dark conditions.
