Rolex Submariner Date Oyster, 41 mm, white gold M126619LB-0003

The Submariner's rotatable bezel is a key functionality of the watch. Its 60-minute graduations allow a diver to accurately and safely monitor diving time and decompression stops. Manufactured by Rolex from a hard, corrosion-resistant ceramic, the Cerachrom bezel insert is virtually scratchproof. A luminescent capsule on the zero marker ensures legibility, no matter how dark the environment. The bezel’s knurled edge is carefully designed to offer excellent grip under water, even with gloves.

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.
