The Rolex Sea-Dweller reference 1665 is a reference prized by collectors. The Sea-Dweller was developed for use by professional deep-sea divers, particularly with its inclusion of a "Helium Escape Valve" or "HEV" on the 9 o”clock side of the case to help the watch survive decompression from dry, pressurized environments.

The earliest Sea-Dweller examples had red printing and are called "Single Red" because of the one line of red text about the 6 o”clock marker, while the "Double Red" (featured here) features the words "Sea-Dweller" and "Submariner 2000" in red text above the 6 o”clock marker.

This example of a rare "Double Red Sea-Dweller" model has a "Mark 4" or "Mark IV" dial and features a beautifully-faded bezel insert that has turned a light "ghost" grey. These Sea-Dweller reference 1665 models are especially valued due to their beefier cases that fit modern tastes for larger watches.

This timepiece has undergone a thorough inspection of water resistance, accuracy, functionality and condition to determine the level of reconditioning required to meet our strict standards. It has also been referenced against technical documents and manufacturer records where available to ensure authenticity and a clean history.
