Omega Seamaster Ploprof 1200M 55x48mm titanium on titanium

Reliable even at 4000 feet beneath the waves, the famous Ploprof has a long history as one of OMEGA’s most trusted divers’ watches.
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 grey silicon nitride 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 lightwatch_case_weight comfort, and again on the dial, with orange aluminum and varnished white hands completing the look.
The metallic style of this watch gives strength to the idea of ocean exploration, and the polished grade 2 titanium “sharkproof” mesh bracelet further adds to the distinct sense of adventure.The watch is delivered in a special presentation box along with an additional grey rubber strap.
