Additionally, this year’s Seamaster Planet Ocean Chrono 45.5 mm is now available in either Sedna™ gold with a black ceramic bezel OR a Sedna™ gold and stainless-steel combo with blue ceramic bezel. It is available with a rubber strap or a stainless steel and Sedna™ gold bracelet.

Another feature is a helium escape valve, for saturation diving; this new Master Chronometer certified Seamaster Planet Ocean Chrono can dive up to 600 m (2,000 ft) and has a 60-hour power reserve. The big picture news, however, is the continued rollout by Omega of METAS, as well as COSC, certification across a wider range of product lines – good news for consumers, as the ubiquity of magnetic fields in modern life makes antimagnetic movements a place where there’s still a bit of room for watchmaking brands to add real functional value.
