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.

This steel on steel configuration was retired in 2019.
