In 2005, OMEGA launched its Planet Ocean line with its maritime heritage in mind. Today, the elegant OMEGA Seamaster Planet Ocean 600M Master Chronometer GMT pays tribute to OMEGA’s diving watch heritage.
The model features a scratch-resistant sapphire crystal and a black ceramic dial with Arabic numerals, a date window at 3 o’clock and a central GMT hand. The bezel, which for the first time combines black and white polished ceramic, is mounted on a 43.5 mm stainless steel case and features a diving scale with contrastingly colored numerals and graduations to differentiate day from night.
The watch also features a honeycomb-design screw-down caseback and a stainless steel bracelet with a patented extendable folding clasp.
The OMEGA Seamaster Planet Ocean 600M Master Chronometer GMT is water-resistant to 600 metres (60 bar \/ 2,000 feet) and equipped with a helium valve. The OMEGA Master Chronometer 8906 calibre at the heart of this watch is visible through the transparent case-back. To obtain Master Chronometer certification, it had to pass eight rigorous tests established by METAS, the Swiss Federal Institute of Metrology. <\/p>\n","protected":false},"featured_media":72285,"template":"","meta":{"_acf_changed":false},"product_brand":[396],"product_cat":[491,493],"product_tag":[],"product_collection":[439],"class_list":["post-172694","product","type-product","status-publish","has-post-thumbnail","product_brand-omega-en","product_cat-new","product_cat-watches","product_collection-seamaster-en","first","outofstock","shipping-taxable","purchasable","product-type-simple"],"acf":{"product_is_new":false,"product_not_available":false,"product_related_stores":null,"product_infos":"","product_features":[{"title":"Features","description":"Antimagnetic<\/b>: The movement resists magnetic fields in excess of 1.5 tesla (15,000 gauss).
