Omega Vintage Seamaster "Ploprof" With Diving Kit - 9.000€

The Omega Seamaster Ploprof is one of the most radical professional dive watches ever created by Omega. Introduced in 1970, its name “Ploprof” comes from the French Plongeur Professionnel, meaning “professional diver.” It was developed during a period when deep-sea exploration and commercial saturation diving were expanding rapidly, and traditional dive watches were reaching their technical limits.

Throughout the 1960s, Omega worked closely with professional divers — including teams involved in offshore oil operations and experimental diving programs — to create a watch capable of withstanding extreme depths and the dangers of helium infiltration. Unlike many dive watches of the era, which relied on helium escape valves to release trapped gas during decompression, the Ploprof was engineered as a monobloc (one-piece) case, making it exceptionally resistant to pressure and eliminating the need for a separate valve.

The original Seamaster Ploprof 600 (reference 166.077) was water-resistant to 600 meters — an extraordinary rating for its time. Its asymmetrical case, massive crown guard, and distinctive red security pusher for locking the bezel gave it an unmistakable industrial aesthetic. Powered by Omega’s robust automatic caliber 1002, it was built first and foremost as a tool for serious underwater work, not as a luxury accessory.

Although its bold design limited mainstream commercial success in the 1970s, the Ploprof earned a reputation as one of the most over-engineered dive watches ever produced. In later decades, Omega revived the model with modern materials and updated movements, but the original 1970 version remains the purest expression of the concept — a purpose-built instrument born from the golden age of professional deep-sea diving.

This particular example has an especially compelling provenance: it belonged to a professional diver, Alain Rodrique. The watch is offered together with elements of his original diving equipment, including his diving knife and his personal dive logbook.

Such documentation and accompanying tools add a powerful historical dimension to the piece. Beyond being a professional instrument like the Omega Seamaster Ploprof was designed to be, this watch becomes a tangible witness to a real diving career. The presence of the diver’s logbook, in particular, reinforces the authenticity of its story and connects the watch directly to the underwater missions it once accompanied.

Altogether, this provenance transforms the watch from a remarkable tool watch into a deeply personal artifact of professional diving history.
