Seamaster Ploprof 1200M 55 x 48 mm

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.

Features
Anti-magnetic: The movement is unaffected by exposure to strong magnetic fields, even those greater than 1.5 tesla (15,000 gauss).
Bi-directional rotating bezel: A bezel which can be turned clockwise or anti-clockwise. Rotating bezels can be used to time events, measure elapsed times, or read second or third time zones.
Chronometer: Label given to a watch which has undergone precision tests and received a certificate from an official body (COSC).
Helium escape valve: Decompression system which allows helium to escape from inside the watch when the watch is worn for professional use in pressure chambers. (Long-term underwater work, crude oil exploration, etc.)
Master Chronometer Certified: Guaranteeing the Swiss industry’s highest standard of precision, performance and magnetic-resistance, as set by the Swiss Federal Institute of Metrology (METAS).
Screw-in crown: Self-locking crown, screwed into the tube of the case, used for highly water resistant divers' watches.
Time zone function: Allows the hour hand to be easily adjusted to different time zones without stopping the watch.
Transparent caseback: A transparent caseback - frequently made of sapphire - makes it possible to see the movement inside the watch.
