Sea-Dweller Vintage Plexi 40mm Steel

The legendary Rolex Sea-Dweller Ref. 1665 is a milestone in diving watch history, flaunting a 40mm stainless steel round case topped with a rotating aluminum bezel. First released in 1967, this professional diver timepiece addressed a significant challenge of saturation diving, with its revolutionary helium escape valve allowing gas to safely exit the watch during decompression.

The deep black dial with luminous hour markers (no numerals) provides excellent visibility underwater. The domed plexiglass crystal is a distinctive characteristic among Sea-Dweller references that feature this vintage element. The robust 40mm stainless steel case houses the reliable automatic caliber 1570 movement with a generous 48-hour power reserve. A solid case back ensures exceptional durability under pressure, offering an extraordinary water resistance rating of 610 meters (2,000 feet). The bidirectional rotating aluminum bezel allows precise tracking of elapsed time underwater.

Master Luxury presents this preowned Rolex Sea-Dweller in excellent condition. This authenticated timepiece has been carefully maintained to preserve its vintage appeal while ensuring reliable performance. The silver stainless steel bracelet is two links short of full length but maintains the original folding clasp integrity. As a true milestone in Rolex's diving heritage, this Sea-Dweller is a true collectors' watch.
