Seamaster Ploprof 1200M

In 1970 OMEGA officially launched a watch that had been created to withstand the crushing pressures endured by divers working deep below the ocean’s surface. It was the Seamaster Professional 600, the so-called “Ploprof” (from plongeur professionnel – French for “professional diver”). It was among the most robust and seaworthy divers’ wristwatches ever made.
