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 Chronograph pays homage to OMEGA’s dive watch heritage. This model, with its scratch-resistant sapphire crystal, features a blue dial with a date window at the 6 o’clock position. The dial presents a small seconds sub-dial, as well as 60-minute and 12-hour counters on one dial for intuitive reading of elapsed time. The blue ceramic unidirectional rotating divers’ bezel, with its Liquidmetal® diving scale, is mounted on a 45.5 mm titanium case and is presented on a blue rubber strap. The OMEGA Seamaster Planet Ocean 600M is water resistant to 60 bar (600 metres / 2000 feet), and has a helium-escape valve. The OMEGA Co-Axial calibre 9300 at the heart of this certified chronometer timepiece can be seen through the transparent caseback.
