Omega Seamaster Planet Ocean is one of its kind in the Omega family. The 45.5 mm titanium case has a blue dial with the date window at the 3 o’clock position. The model comes with a blue, unidirectional, rotating diver’s bezel which helps the divers to calculate their dive times. The titanium case is mounted on a blue rubber strap. The model is covered with scratch-resistance sapphire crystal. The timepiece has high water-resistance of 600 metres and helium escape valve, especially crafted for professional divers. The Omega watch has a Co-Axial calibre of 8500 which can be seen because of the transparent caseback. The self-locking screw-in crown is used by high water-resistance divers.
