Conquering the deep. The Oyster Perpetual Sea-Dweller in a yellow Rolesor version – a combination of Oystersteel and 18ct yellow gold – brings the lustre of gold to the range for the first time. This new version features a helium escape valve and a 60-minute graduated Cerachrom insert in black ceramic, and is guaranteed waterproof to a depth of 1,220m (4,000ft). #Rolex #SeaDweller #Perpetual
