It was with OMEGA’s maritime legacy in mind that the brand launched its Planet Ocean line in 2005. Today, the stylish OMEGA Seamaster Planet Ocean 600M Master Chronometer pays homage to OMEGA’s dive watch heritage.  This model, with its scratch-resistant sapphire crystal, features a blue ceramic dial with Arabic numerals and a date window at the 3 o’clock position. The blue ceramic unidirectional bezel with OMEGA Liquidmetal™ diving scale is mounted on a 43.5 mm stainless steel case.  Other features include an alveol screw-in caseback and a stainless steel bracelet with patented extendable foldover clasp
