Rolex Sea-Dweller 1665

The Rolex Sea-Dweller 1665, known as the "Double Red" in its early iterations, is a pioneering dive watch introduced for professional saturation divers. Featuring a 40mm Oystersteel case, a plexiglass crystal, and a helium escape valve, it offers water resistance up to 610 meters (2,000 feet). Early models are distinguished by the "Double Red" text on the dial, while later "Great White" versions feature an all-white dial inscription. Powered by the robust Caliber 1575 movement, the 1665 is a vintage icon cherished by collectors.
