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 pays homage to OMEGA’s dive watch heritage. This model, with its scratch-resistant sapphire crystal, features a black dial with a date window at the 3 o’clock position. The black ceramic unidirectional rotating divers’ bezel is mounted on a 45.5 mm stainless steel case on a black rubber strap. The OMEGA Seamaster Planet Ocean 600M is water resistant to 600 meters / 2000 feet / 60 bar, and has a helium-escape valve. The OMEGA Co-Axial calibre 8500 at the heart of this certified chronometer timepiece can be seen through the transparent caseback.
