OMEGA Seamaster Planet Ocean 600M

Omega's Seamaster Planet Ocean 600M ref. 215.92.46.22.01.007 is a GMT watch with a 45.5 mm black ceramic case. The case measures 17.38 mm thick with a 51.5 mm lug-to-lug span, and a unidirectional rotating bezel surrounds the dial. A domed sapphire crystal with antireflective coating on both sides covers the black dial. Inside is the self-winding calibre 8938, a Master Chronometer movement with Co-Axial escapement, resistant to magnetic fields up to 15,000 gauss, with a silicon balance spring and 60 hours of power reserve. The worldtimer function pairs with a date display, and the transparent caseback shows the movement. A black rubber strap closes with a ceramic foldover clasp. The screw-in crown backs up the case's 600 metre water resistance rating.
