The Oyster Perpetual Rolex Deepsea in Oystersteel with a black ceramic bezel and an Oyster bracelet. It features a D-blue dial and large luminescent hour markers. Waterproof to a depth of 12,800 feet (3,900 metres) with a unidirectional 60-minute rotatable bezel, the Rolex Deepsea is amongst the ultra-resistant divers’ watches engineered by Rolex for deep-sea exploration. 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.
