The Omega Seamaster “Ploprof” COMEX was inspired by COMEX’s early search for a dive watch that could survive unprecedented depths and the unique challenges of saturation diving. In the late 1960s, before their partnership with Rolex, COMEX collaborated with Omega to test and refine the Ploprof (“Plongeur Professionnel,” or “professional diver”), a purpose-built watch engineered to be virtually impermeable to helium and withstand pressures far beyond standard diving limits. Its monobloc case construction, distinctive crown-lock system, and massive bezel were all designed for maximum strength and security during prolonged high-pressure exposure. COMEX divers used these watches extensively during deep-sea experiments and record-setting dives, proving the Ploprof’s capabilities in real-world conditions. This collaboration not only cemented the Ploprof’s reputation as one of the most robust mechanical dive watches ever made but also set the stage for COMEX’s later, even more famous partnerships with Rolex.
