The Omega Seamaster Ploprof is one of the most extreme professional dive watches ever created, engineered to master the deepest underwater environments. First introduced in 1970, the Ploprof — short for Plongeur Professionnel — was developed with input from legendary divers and designed with a distinctive monobloc case, crown locking system, and bezel security pusher for maximum safety under pressure. Modern Ploprof models are crafted from lightweight titanium or stainless steel and powered by Omega’s Co-Axial Master Chronometer movements, offering water resistance up to 1200 meters and anti-magnetic durability. Bold, unconventional, and built without compromise, the Omega Seamaster Ploprof is one of the most unique Omega watches for sale, prized by professional divers and collectors who value innovation and heritage in equal measure.
