  • Omega Seamaster Planet Ocean 600m Chronograph ( Watch Review

    WatchBox Reviews
    Published on Feb 25, 2019

    The Omega Seamaster Planet Ocean 600m Chronograph features a 45.5mm stainless steel case surrounding a black dial on a stainless steel bracelet with a folding buckle. This Omega Seamaster Planet Ocean dive watch is an aggressively styled alternative to the Rolex Deepseas Sea-Dweller, and Omega's offering brings full chronograph capability to the table.

    With a water resistance rating of 600 meters and a helium escape valve for saturation divers, the Planet Ocean Chronograph is suitable for use in all professional diving scenarios. A unidirectional dive bezel with ceramic insert adds to the functionality, and super luminova on the dial and bezel ensures legibility of the watch in the dark.

    Omega includes a co-axial chronometer caliber 9300 chronograph movement. COSC chronometer certification combines with George Daniels' co-axial escapement technology for precision and reduced maintenance requirements. An Omega Si14 silicon hairspring ensures robust resistance to magnetism. The caliber 9300 boasts a 60-hour power reserve thanks to twin mainspring barrels in series.

    The caliber 9300 also includes the refinement of a column wheel function selector with vertical clutch chronograph engagement. A full balance bridge with free sprung index contributes to shock resistance. Finally, the movement includes both hacking seconds (stop seconds) and a "time zone" feature that permits independent adjustment of the hour hand and date while traveling.

    Functions include hours, minutes, small seconds, date, helium release valve and chronograph. The watch also measures 19.4mm in thickness and 52mm from lug-to-lug.


    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 small seconds dial, a date window and a central chronograph hand. Sixty-minute and 12-hour counters are found on the same dial at the 3 o’clock position, allowing for intuitive reading of the elapsed time. The black ceramic unidirectional rotating divers’ bezel is mounted on a 45.5 mm stainless steel case on a stainless steel bracelet.

    The OMEGA Seamaster Planet Ocean 600M is water resistant to 600 metres / 2000 feet / 60 bar, and has a helium-escape valve. This certified chronometer timepiece is powered by the OMEGA Co-Axial calibre 9300 which can be seen through the transparent caseback.
