Rolex Deepsea in Oystersteel with a Cerachrom bezel insert in black ceramic

The Oyster Perpetual Rolex Deepsea in Oystersteel with a Cerachrom bezel insert in black ceramic and an Oyster bracelet.

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.

The dial’s luminescent Chromalight display is an innovation that improved visibility in dark environments, an essential feature for divers.

Hour markers in simple shapes – triangles, circles, rectangles – and broad hour and minute hands enable instant and reliable reading to prevent any risk of confusion underwater.

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.

The Oyster bracelet is a perfect alchemy of form and function, aesthetics and technology, designed to be both robust and comfortable.

It is equipped with an Oysterlock clasp, which prevents accidental opening, and an ingenious Glidelock, allowing fine adjustments of the bracelet without using any tools — and allowing it to be worn comfortably over a diving suit.
