The Oyster Perpetual Submariner Date in 18 ct yellow gold with a Blue Cerachrom bezel and a blue dial with large luminescent hour markers. It features a unidirectional rotatable bezel with Cerachrom insert and solid-link Oyster bracelet. The latest generation Submariner and Submariner Date remain faithful to the original model launched in 1953. In watchmaking, the Submariner represented a historic turning point; it set the standard for divers’ watches.
The Submariner’s rotatable bezel is a key functionality of the watch. Its engraved 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.
A blue ceramic bezel with a blue dial on a Submariner is reserved for a watch that incorporates precious metal: Rolesor, a combination of Oystersteel and 18 ct yellow gold, or a Submariner in solid 18k yellow gold or solid 18k white gold.
