Omega Seamaster Ploprof 1200M 55x48mm 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 Master Chronometer Calibre 8912, featuring revolutionary technology renowned for its anti-magnetic resistance, chronometric performance, and precision.
The grade 5 titanium case includes an orange ceramic bezel ring, with the numerals, triangle and scale, all filled with Super-LumiNova for increased visibility.The dial is also grade 5 titanium, with varnished orange and 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.
