The Omega Planet Ocean collection became part of the Seamaster family in 2005 and pays homage to Omega’s rich maritime legacy and dive watch heritage. This Omega Seamaster Planet Ocean Men’s Automatic Co-Axial Divers watch boasts water resistance to 600 metres, has a helium-escape valve and has passed 8 rigorous tests set by META (The Swiss Federal Institute of Metrology) to achieve Master Chronometer status. This diver’s instrument features a 43. 5mm stainless steel case secured with a stainless steel bracelet with a patented extendable fold-over clasp. A blue ceramic uni-directional bezel with OMEGA Liquidmetal™ diving scale surrounds the blue ceramic dial, which is protected by a sapphire crystal lens. Arabic numerals and a date window sit on the dial and are powered by the Omega Master Chronometer calibre 8900, with the movements of the watch on display through the transparent case back.
