Reliable even at 4000 feet beneath the waves, the famous Ploprof timepiece has a long history as OMEGA's most water-resistant divers' watch. While retaining the original sturdy and bold appearance, this new edition has been updated with OMEGA's Co-Axial Master Chronometer Calibre 8912, featuring revolutionary technology renowned for its anti-magnetic resistance, chronometric performance, and precision. The unique case combines 18K Sedna™ gold along with grade 5 titanium for lightweight comfort. Sedna™ gold has also been used on the hands and indexes, with Super-LumiNova for increased visibility. Completing the look, a polished blue bezel has been added with OMEGA Ceragold™ numerals, as well as a blue lacquered dial.
