The horizon of the deep

The Oyster Perpetual Deepsea Challenge in RLX titanium with a Cerachrom bezel insert in black ceramic and an Oyster bracelet.

Ceramic Bezel and Luminescent Display

Legendary divers’ watch

The 60-minute graduated, unidirectional rotatable bezel of the Deepsea Challenge 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.

Intense black dial

For legibility underwater

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.

RLX titanium

Ultralight resistance

RLX titanium is a grade 5 titanium alloy selected by Rolex for its weightlessness and resistance to deformation and corrosion. Although insensitive to abyssal pressure, the experimental watch that accompanied James Cameron in the Mariana Trench still posed a wearability problem due to its weight, as it was made of 904L steel.

The use of RLX titanium to create the case and bracelet of the Deepsea Challenge considerably lightened its weight: it is 30 per cent lighter than the experimental watch that inspired it. The watch also features a particularly visible grain in the satin finish on the bracelet and the case – with the exception of the crown guard. In order to highlight the curved profile of the lugs, the top edges have been chamfered and polished.

The Oyster bracelet

Alchemy of form and function

The innovative Rolex Glidelock and Fliplock extension systems require no tools for use. Made of RLX titanium, the Deepsea Challenge’s Oyster bracelet is equipped with both the Fliplock extension link and the Rolex Glidelock system.

Made of RLX titanium, the Deepsea Challenge’s Oyster bracelet is equipped with both the Fliplock extension link and the Rolex Glidelock system. Thanks to the combination of these two extension systems, the watch can be worn comfortably over a diving suit up to 7 mm thick.
