The OMEGA Ploprof, short for "Plongeur Professionnel," was introduced in 1970 as a professional diver's watch in the OMEGA Seamaster collection. Known for its robust construction and innovative design, the Ploprof quickly gained acclaim for its reliability in deep-sea exploration. With its distinctive asymmetric case and durable materials, the OMEGA Ploprof remains a trusted companion for divers and collectors seeking a timepiece built to withstand the rigors of underwater exploration.
