Ceramic Bezel and Luminescent Display Legendary divers’ watch
The 60-minute graduated, unidirectional rotatable bezel of the Sea-Dweller 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.
