ROLEX SEA-DWELLER

Rolex created the Oyster Perpetual Sea-Dweller in 1967 to meet the challenge of prolonged underwater mission. Subsequently improved in close partnership with Comex (Compagine Maritime d'Expertises) professionals, it is now waterproof to 1,220 meters (4,000 feet). The Sea-Dweller is specifically designed for saturation diving. Thanks to its helium valve, it can withstand decompression on ascent and master the return to the surface - the final phase of deep-sea exploration.
