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 continuous small seconds, a date window and a central chronograph hand. Thirty-minute and 12-hour recorders are found at the 3 o’clock and 6 o’clock positions, respectively. The diamond-set, unidirectional rotating bezel is mounted on a 37.5 mm stainless steel case on a black leather strap. The OMEGA Seamaster Planet Ocean 600M is water resistant to 600 metres / 2000 feet / 60 bar, and has a helium-escape valve. This timepiece is powered by the Co-Axial calibre 3313.
