AT HOME IN THE OCEANS
The Oyster Perpetual Submariner is the quintessential divers’ watch, the benchmark in its genre. This iconic timepiece has evolved with a series of patented Rolex technical innovations, guaranteeing its reliability and precision down to depths of 300 meters (1,000 feet). At home in the oceans, where it remains an indispensable instrument for every diver, the Submariner has also conquered terra firma as the watch of action with a rugged elegance of its own.
UNIDIRECTIONAL ROTATABLE BEZEL
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.
The Chromalight display on the dial is an innovation that pushes the boundaries of visibility in dark environments. The blue glow lasts up to eight hours with a uniform luminosity throughout, practically twice as long as that of standard luminescent materials.
TRIPLOCK WINDING CROWN
The Triplock winding crown is a triple waterproofness system designed especially for divers’ watches. Developed by Rolex, it resists water pressure to depths of 300 meters (1,000 feet) on the Submariner models, and up to 3,900 meters (12,800 feet) on the Rolex Deepsea.
