In 2009, the brand created a completely updated version of its world-renowned Seamaster Professional 600, a watch able to withstand the crushing pressure divers experienced while exploring the ocean’s depths. The Seamaster Ploprof 1200M combines enhanced modern technology with an iconic timepiece, paying homage to OMEGA’s rich diving heritage.
This model features a black dial with a date window between the 4 and 5 o’clock positions. The black bi-directional rotating bezel, with its numerals and diving scale painted with white Super-Luminova inside the sapphire bezel ring, is mounted on a 55 x 48 mm stainless steel case and is presented on a “Sharkproof” stainless steel bracelet.
The OMEGA Seamaster Ploprof 1200M is water resistant to 1200 metres / 4000 feet / 120 bar, and boasts a screw-in crown, automatic helium escape valve and bezel security pusher. Powering this professional divers’ watch is the OMEGA Co-Axial calibre 8500.
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.
Label given to a watch which has undergone precision tests and received a certificate from an official body (COSC).
The day of the month, displayed in a window on a watch dial at the 3 or 6 o’clock position, or within a subdial at 9 o'clock.
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.)
Self-locking crown, screwed into the tube of the case, used for highly water resistant divers' watches.

Stainless steel is certainly the most conventional of watchmaking materials for outer craftsmanship, and offers beauty, strength and affordability. OMEGA uses 316L stainless steel. Known for its corrosion-resistance and high lustre after polishing, this material is often the ideal choice for watches in both daily-use and high-stress situations such as diving and adventure.

To really appreciate the finer details of a timepiece, OMEGA uses synthetic sapphire crystal with a highly scratch-resistant and anti-reflective treatment. Before the machining and finishing processes take place, the sapphire crystals are produced under the Verneuil process, also called flame fusion. It involves the melting of the raw substance using oxyhydrogen flame and the crystallisation of the melted droplets to form a cylinder. Graded 9 on the Mohs-hardness scale (graded 1-10), the resulting sapphire crystals are virtually scratch-proof and very hard, ensuring an unhindered vision at all times.
Self-winding movement with Co-Axial escapement. Free sprung-balance, 2 barrels mounted in series, automatic winding in both directions. Bridges and the oscillating mass are decorated with exclusive Geneva waves in arabesque.
