Notes

Comex's collaboration with Rolex started in early 1971. Prior to that date, Comex had cooperated with Omega, for the testing of the design of the Ploprof (short for plongeur professionel), of which a prototype series was tested during Janus II and Physalie V (Nov. 1970) However the Ploprof had a major problem, with its ?explosion? during the decompression time after a saturation dive, due to the helium build-up inside the case. Rolex had noted this problem on the early Sea-Dwellers that were not fi tted with helium valves and quickly moved to solve this problem by fi tting the valves on the side of the case (patent number 492246
