Rolex Sea-Dweller: A professional diver’s watch

The Rolex Sea-Dweller was launched in 1967 as a robust solution for professional saturation divers. Developed in collaboration with COMEX and the US Navy Sealab project, it expanded on the Submariner’s capabilities by introducing a thicker case and the groundbreaking helium escape valve. This valve prevents the watch crystal from popping off during decompression by safely releasing helium gas buildup inside the case.

The original Sea-Dweller reference 1665, known as the “Double Red” for its red dial text, had a water resistance of 610 metres and was designed without the Cyclops lens to maintain crystal strength. Over time, Rolex evolved the Sea-Dweller with models like the “Triple Six” (ref. 16660), which doubled the depth rating to 1,220 metres and introduced a sapphire crystal. The collection was briefly discontinued in 2009 but reintroduced in 2014 with larger 43mm cases and the addition of the Cyclops lens in references 126600 (steel) and 126603 (two-tone).

Craftsmanship and innovation of the Sea-Dweller

Every Sea-Dweller is expertly crafted with corrosion-resistant Oystersteel, fitted with a robust sapphire crystal and sealed by a screw-down case back. The helium escape valve, a patented innovation, is key to the watch’s ability to withstand extreme pressures encountered during deep saturation dives.

The Sea-Dweller is powered by Rolex’s in-house automatic movements, engineered for precision and durability even in the harshest conditions. Its waterproof rating of up to 1,220 metres (4,000 feet) makes it a reliable companion for professional and recreational divers alike.
