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.
