The Ploprof, whose name derives from an idea of the french-speaking team which developed the watch based on the words PLOngeur PROFessionnel, which means Professional Diver, represent the very first waterproof model specifically ideated and built for professional divers. It has been presented to the world in 1970 only after 4 years of intense tests firs at 600 m of depth and later at 1000 m in the Golf du Lion off the coast of Marseilles. The first generation watches were simply marked 600 on the dial while the second generation, the ref. ST166.0077 as the present watch were marked 600 m/2000 ft. Massive and unique in its design, this Ploprof prototype is a rare opportunity that will surely appeal to collectors of exceptional tool watches. Coming in at a beefy 45 mm diameter case in stainless steel the watch was engineered to withstand the crushing pressures of deep diving. The present watch is also fitted with the sought-after mesh bracelet and presented in a stunning condition. It features a dark blue original dial with bidirectional revolving black bezel calibrated to 60 units, luminous baton hour marks and signed “Omega”, “Automatic”, “Seamaster”, “600 m/2000 ft”, “Professional”, “Swiss Made”. This watch also has hours, minutes and second luminous hands with date indicator at 3 o’clock and the winding crown is completely original. Unique for its history and the unusual design, the present lot is a very notable piece of collection for real watches lovers and connoisseurs.
