Saturation divers who had previously been issued with Rolex Submariners found that during decompression, the pressure inside the watch would force its way out through the weakest point which usually resulted in the loss of the plexiglass. In response to this, Rolex developed the Sea-Dweller. With a helium escape valve on the side, a greater depth rating of 610 meters and the removal of the cyclops from the crystal, the Sea-Dweller is a true tool watch and has been favoured by professional divers ever since its introduction. This particular version of the reference 1665 succeeded the Double Red Sea-Dweller in 1977. The most noticeable difference was that the red text on the dial was replaced with white text, earning the watch the nickname of 'Great White' amongst collectors.
