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 white dial with a date window at the 3 o’clock position. The diamond-set, unidirectional rotating bezel is mounted on a 37.5 mm 18K red gold case on a white leather strap. The OMEGA Seamaster Planet Ocean 600M is water resistant to 600 metres / 2000 feet / 60 bar, and has a helium-escape valve. The OMEGA Co-Axial calibre 8521 at the heart of this timepiece can be seen through the transparent caseback.
