In 1970 OMEGA launched the Seamaster Professional 600, the so-called “Ploprof” (the first letters of plongeur professionnel – the French words meaning “professional diver”), one of the most rugged, robust and seaworthy divers’ wristwatches ever manufactured. Last year OMEGA introduced a completely updated version of the divers’ classic. Equipped with a Co-Axial calibre 8500, the new Ploprof 1200M is, as its name suggests, water resistant to an astounding 1200 metres (4000 feet, 120 bar) and it is an artful union of its ancestor’s legendary features and OMEGA’s state-of-the-industry Co-Axial technology.
