The Sea-Dweller’s design is based on the famed Submariner, yet is expertly engineered to withstand even more demanding conditions. A gas escape valve makes the Sea-Dweller suitable for saturation diving, while the patented Ringlock system means that the Sea-Dweller is able to withstand pressure up to a dizzying 3,900 metres.
Designed for perfect legibility in dark conditions, Chromalight hour markers and luminescent hands provide a long-lasting blue. The Rolex Glidelock system allows you to extend the bracelet for comfort, up to 20mm. Available with a 43 or 44mm case, the Sea-Dweller comes in Oystersteel or Oysterteel and yellow gold. The reliable self-winding 3235 calibre movement and 70-hour power reserve provide peace of mind.
The story of the Sea-Dweller has its origins in the ambitious SEALAB research project. Saturation divers, whose breathing gas contains helium to help avoid decompression sickness, were finding that after decompression, the crystal on their Rolex Submariners was sometimes popping off. The reason, it was discovered, was that tiny helium particles were getting into the watch. The Sea-Dweller therefore introduced the ingenious gas escape valve to meet the needs of these extreme divers. The sheer amount of time that these watches spent underwater earned them the moniker ‘Sea-Dweller.’
