The Oyster Perpetual Deepsea Challenge is crafted from RLX titanium – a first for a Rolex watch. This grade 5 titanium alloy was selected by the brand for its weightlessness and resistance to deformation and corrosion. The properties of this material make it difficult to work with, prompting Rolex to develop special production processes for the manufacturing and finishing of the RLX titanium components. The watch features a particularly visible grain in the satin finish on the bracelet and the case, with the exception of the crown guard. To highlight the curved profile of the lugs, the top edges have been chamfered and polished. #Rolex #DeepseaChallenge #Perpetual For more details about this watch see the link in the profile.
