Seamaster Ploprof 1200M 55 x 45 mm

This special Ploprof takes its design cues from OMEGA’s 1970s original.

Crafted in O-MEGASTEEL, it has a sun-brushed dial in OMEGA’s own Summer Blue with a gradient finish to reflect the watch’s level of water resistance. The bezel is produced in transparent sapphire crystal, varnished blue on the back, to reveal the light blue diving scale beneath.

The iconic mono-bloc case includes the famous screwed-in crown and the characteristic security pusher at 2 o’clock, which on this edition sports a ring in blue ceramic. In keeping with the colour code, OMEGA has filled the varnished hands and indexes with a unique light blue Super-LumiNova.

Turning the watch over reveals a laser-engraved commemorative Seamaster logo, framed by engraved waves and depicting a trident-bearing Poseidon and two seahorses: OMEGA’s 1956 original and the brand’s current design. Behind which sits the OMEGA Co-Axial Master Chronometer calibre 8912. An original-style blue rubber strap completes the look.

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.
