The Sea Dweller ref. 1665 model was launched in 1971. It is the first diver's watch with a Rolex patent valve in the band and guaranteed waterproof to 610 meters depth. The valve was first developed on the Submariner model and allows helium and other gases to escape, enabling the watch to stand compression. The first Sea Dweller model with red printing and 'Submariner 2000' on the dial is a version of the Submariner model. It was discontinued in 1973 and the revised form with white printing on the dial and without the 'Submariner 2000' was launched.
