Beyond the requisites of a professional diver’s watch (300 metres/1000 feet) this model is water resistant to 600 metres/2000 feet. Other features that distinguish this as a professional diver’s instrument are the screw-in crown and screw-down case back, the helium escape valve, the fluted uni-directional rotating bezel featuring a luminous dot and the highly visible hands
True to the Seamaster’s roots, the Calibre 3313 high-quality self-winding mechanical movement with a power reserve of 52 hours drives the Planet Ocean Chronograph. The Co-Axial escapement, proprietary Omega technology, considerably reduces friction in the heart of the watch mechanism and offers improved long-term reliability and accuracy. A free-sprung balance further improves this COSC-certified chronometer. The column-wheel mechanism serves to perfect the chronograph’s performance. It ensures a smooth start to the sweep of the seconds hands when the chronograph is activated and provides precision stop and reset functions. The rhodium-plated movement has been given a luxurious finish and the bridges are decorated with attractive circular graining, Geneva waves and gold-plated engravings and the screw-down case back features a seahorse medallion.
