Rolex Deepsea Challenge Oyster, 50 mm, RLX titanium M126067-0001

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 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.
