The OMEGA Seamaster Aqua Terra Worldtimer keeps track of time across the globe and offers ingenuity and cutting‑edge innovation wherever you are on Earth. Furthermore, today’s Master Chronometer models are tested and certified at the highest level by an independent Swiss authority. This guarantees that their incredible heart is accurate, reliable and supremely resistant to magnetic fields. The Worldtimer wristwatches consist of a 43 mm polished case in stainless steel or 18K Sedna™ gold, which is attached to a bracelet or strap made of rubber, leather of metal. To mirror the decks of luxury yachts, the dials of these Swiss watches are vertically striped with a ""teak"" motif. Around the dial, you’ll find a list of international destinations including OMEGA’s hometown of Biel. At the centre of these sophisticated wristwatches for men and women, planet Earth is represented by a cutting‑edge view of the continents, achieved on a titanium plate with OMEGA’s most advanced laser‑ablation technology. Scratch‑resistant sapphire crystal keeps the timepiece protected at all times.
