Seamaster Planet Ocean 600 M OMEGA Co-Axial Chronograph

From the retailer listing

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 orange unidirectional rotating divers’ bezel is mounted on a 45.5 mm stainless steel case on an orange rubber strap. The OMEGA Seamaster Planet Ocean 600M is water resistant to 600 meters / 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.
