Rolex Sea-Dweller

A steel Rolex Deepsea Sea-Dweller with a blue-black dial

Sea-Dweller or Deepsea, old or new: tell us about yours and we’ll email and text you a price.

The Sea-Dweller was developed in the late 1960s as a deeper-rated sibling of the Submariner for professional divers. Its helium escape valve lets gas trapped in the case escape during decompression after saturation dives, and the watch has been issued to Comex divers since 1977.
