Rolex Sea-Dweller 16600 40mm (2004)

The Rolex Sea-Dweller 16600 is a professional-grade dive watch engineered for extreme underwater performance. This 2004 example features a crisp black dial with luminous hour markers and Mercedes hands, encircled by a unidirectional rotating bezel with an engraved black aluminium insert. Unlike the Submariner, the Sea-Dweller includes a helium escape valve, allowing it to withstand saturation diving depths up to 1,220 meters (4,000 feet). Its robust 40mm stainless steel case, solid Oyster bracelet, and lack of a Cyclops lens over the date further distinguish it as a tool watch built for the most demanding environments.
