RARE Omega Vintage PLOPROF Seamaster 600m Professional Diver Watch Serviced. Developed in conjunction with Comex and the legendary Jacques Cousteau, Omega conceived and developed what was probably the first waterproof watch designed and built solely for the diving professional. The watch took 4 years to come to the market after extensive testing and arrived in 1970. It was nicknamed PloProf by the French speaking development team and derives from the French term PLOngeur PROFessionnel (Professional Diver). Comex used early models of the PloProf and continued their research into living underwater for prolonged periods.
One Issue that still concerned Comex was helium infiltration, which carried the danger of causing a watch crystal to pop out during decompression. There is no proof that this problem occurred with any Ploprof, and later tests by the American diving research centre Ocean Systems Inc.In Tarrytown, NY, certified that the Ploprof was more watertight than a submarine. However, Comex wanted to be sure to combat the helium infiltration issue, rather than trust improved watch-case sealing. They chose to continue their research work with Rolex and Doxa to test their new Helium Expulsion Valve (HEV) designs. HEVs were incorporated in the Rolex SeaDweller which Comex used reliably for many, many years. During the 4 year gestation period the PloProf was tested to 600m at the Omega factory and to 1000m in the Gulf of Lion, off the coast of Marseilles. It was used by Commander Jacques Cousteau during his series of experiments designed to test man's physical and psychological capacities when working at depths of 500m. During operation Janus in 1970 3 Comex divers wore the watch at a depth of 250m for 4 hours a day, for eight days whilst exploring the sea floor in the Gulf of Ajaccio. The watch was very expensive and the top of Omegas range at the time of its launch. It is unclear, and unlikely, that Omega recouped its development costs in the models life-span between 1970 and 1979. The watch was a hit with professional divers but its price, approximately twice that of a Rolex Submariner, kept many hobby divers away. For information the Swiss retail price in 1973 was CHF 690 on isofrane strap, and CHF 720 on Milanese bracelet (known these days as mesh). These factors mean that today these watches are reasonably rare.
