It was with OMEGA’s maritime legacy in mind that the brand launched its Planet Ocean line in 2005. The stylish OMEGA Seamaster Planet Ocean 600M GMT pays homage to OMEGA’s dive watch heritage.
This model, with its scratch-resistant sapphire crystal, features a laquered black dial with a date window at the 3 o’clock position and a central GMT hand. The polished black ceramic bi-directional rotating bezel is mounted on a 43.5 mm stainless steel case on a stainless steel bracelet.
The OMEGA Seamaster Planet Ocean 600M GMT is water resistant to 60 bar (600 metres / 2000 feet), and has a helium-escape valve. The OMEGA Co-Axial calibre 8605 at the heart of this certified chronometer timepiece can be seen through the transparent caseback.
