Rolex developed the Sea-Dweller model in close connection with the French deep-sea diving firm Comex (Compagnie Maritime d'Expertises). When divers would ﷽go under water and come back to the surface, their watches would tend to fill with helium and would then be vulnerable to damage or explosion from an imbalance in pressure.

To counteract this, Rolex devel𝔉oped the gas escape valve at 9 o'clock that the user could depress to release the helium from the case.

At first, this one-way gas valve was featured on special Ref. 5513 models, however the model was re-named Ref. 5514. By 1967, the model was re-named again and launched as the Ref. 1665. It was ultimately tested and app𒁏roved for depths down to 2000 feet, or༒ roughly 610 meters.

The first generation of this reference featured 'Sea-D▨weller Subma♔riner 2000' in red printing. As these dials were in production for a limited period of time, they are much more collectible in the market today.

The present watch has its original 'Double-Red' dial as well as a factory replacement dial with printing in white, as the original owner had purchased a 🐼second dial when the watch was serviced in 1990.
