Ceramic Bezel and Luminescent Display
The 60-minute graduated, unidirectional rotatable bezel of the Rolex Deepsea enables divers to precisely and safely monitor their dive and decompression times. The triangular ‘zero’ marker of the graduation is visible in the dark thanks to an embedded capsule containing a luminescent material emitting a long-lasting blue glow. The graduation on the bezel is coated via PVD (Physical Vapor Deposition) with a thin layer of yellow gold. The blues found in the compression ring, the dial and the Cerachrom bezel insert combine to create a subtle oceanic palette that is accentuated by the 18 ct yellow gold of the case and the Oyster bracelet.
