The Rolex Sea-Dweller is a masterful timepiece born out of the need for a watch to accompany professional divers as they descend underwater at more than 300 meters. Rolex met this need in 1967 with the original Rolex Sea-Dweller ref. 1665. Over the next four years, Rolex worked to patent their helium escape valve feature in the Sea-Dweller collection and, thus, the Sea-Dweller was finally released to the public in 1971. Since then, the Rolex Sea-Dweller has been a staple in the luxury brand’s lineup, and the timepieces have continually broken industry deep-sea diving records. 

The Rolex Sea-Dweller Two-Tone 126603 is a stellar example of Rolex’s craftsmanship and attention to detail. This Rolex watch stands out among all Rolex watch collections due to its gorgeous yellow gold and Oystersteel Cerachrom bezel. The numbers on the bezel are set in a 60-minute unidirectional rotating format, so divers can easily monitor their time underwater. 

The black ceramic dial features luminescent hour markers and a perpetual date and Cyclops lens. This watch is waterproof up to 4,000 feet and uses the patented helium release valve. The Rolex Sea-Dweller Two-Tone 126603 features a 43mm case made of 18K yellow gold and Oystersteel in a two-tone color scheme as elegant as the watch is functional. The lens is crafted from scratch-resistant sapphire, and the watch boasts perpetual, mechanical, and self-winding movement features.

This watch has a precision of -2/+2 seconds per day and allows for stop-seconds while time setting. It also has a power reserve of approximately 70 hours. The Oysterlock safety clasp means it will never fall off, no matter what type of sea diving exploration you get up to.
