Titanium on titanium


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 includes a polished black ceramic bezel ring, with the numerals, triangle and scale, all filled with Super-LumiNova for increased visibility. Grade 5 titanium has been used as the case and clasp material for lightweight comfort, while the lacquered black dial is complemented by orange aluminum and varnished white hands.

The classic dark style of this watch is ready for the ocean depths, and the polished grade 2 titanium "sharkproof" mesh bracelet further adds to the sense of exploration and adventure. The watch is delivered in a special presentation box along with an additional black rubber strap.




The movement is unaffected by exposure to strong magnetic fields reaching 1.5 tesla (15,000 gauss).
