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