Accompanied by Omega Certificate dated 8 August 2005 and Extract of Records confirming the manufacture of the present watch in 1974 and its delivery to the Swiss market on 25 February 1974.

The Seamaster 600 Professional model, also called "PLOPROF" for PLOngeur PROFessional, professional diver, was launched in 1970. It took over 4 years of study and research to design this watch. The monocoque cases of the model are made out of one piece of massive stainless steel and fitted with an extremely strong tempered mineral crystal and a special twin-locking crown.

It was tested to a depth of 600 meters at the factory and to 1'000 meters in the Gulf of Lion off the coast of Marseilles where it was notably used by Commander Jacques Cousteau during a series of experiments designed to test man's physical and psychological capacities to work at depths of around 500 metres.

During operation "Janus" in 1970 in collaboration with the renowned company COMEX, then world leader in sub-sea engineering and in manned and unmanned sub-sea interventions, three divers wore the Seamaster 600 for eight days four hours a day.

It was also scrupulously analysed by the American diving reseach centre Ocean Systems Inc. in Tarrytown, NY, which concluded that, taking into account the appropriate proportions, the watch is more resistant than a submarine.

The rarity of the present watch is further enhanced by its excellent overall condition.

The "PloProf" is described and illustrated in Omega Saga by Marco Richon, pp. 136 & 137.
