The Rolex Deepsea Challenge Watch features a Cerachrom bezel insert in black ceramic and an Oyster bracelet, an intense black dial and large luminescent hour markers.
It is an extension of the experimental watch created in 2012 to accompany James Cameron in the Mariana Trench.
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.
