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 sleek black 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.
Oystersteel

Rolex uses Oystersteel for its steel watch cases. Specially developed by the brand, Oystersteel belongs to the 904L steel family, alloys most commonly used in high-technology and in the aerospace and chemical industries, where maximum resistance to corrosion is essential. Oystersteel is extremely resistant, offers an exceptional finish once polished and maintains its beauty even in the harshest environments.
