The Rolex Sea-Dweller 43 Ref. 126600 in black represents the pinnacle of professional diving watches. Built for extreme depths, this timepiece features a robust 43mm Oystersteel case with a unidirectional rotatable bezel and helium escape valve—essential for saturation diving operations.

The dial showcases luminous Mercedes hands and hour markers for optimal visibility in low-light underwater conditions. Water-resistant to 4,000 meters, the Sea-Dweller combines Swiss precision with legendary durability, making it equally at home in the deep ocean or on land.

Powered by the Rolex Calibre 3235 automatic movement, this watch delivers exceptional accuracy and a 70-hour power reserve. The Oyster bracelet with Glidelock extension system accommodates wetsuits, while the Cyclops lens magnifies the date window for easy reading.

A professional instrument trusted by divers and collectors worldwide, the Sea-Dweller 43 is a statement of excellence and capability.
