The Seamaster Aqua Terra is a superb tribute to OMEGA’s rich maritime heritage. In this 41 mm model, the symmetrical case has been crafted from 18K Sedna™ gold, with a wave-edged design featured on the caseback.

The sun-brushed blue-grey dial is distinguished by a horizontal “teak” pattern, along with a date window at 6H and an opaline Small Seconds subdial featuring an 18K Sedna™ gold ring. The design is further complemented by 18K Sedna™ gold hands and indexes filled with white Super-LumiNova, as well as sandblasted minutes and seconds tracks on the dial and subdial.

Presented on a polished and brushed bracelet, this timepiece is powered by the OMEGA Co-Axial Master Chronometer calibre 8917, certified at the industry’s highest standard by the Swiss Federal Institute of Metrology (METAS).
