Aqua Terra 150M Seamaster Sedna™ gold Master Chronometer 220.55.38.20.99.001

The Seamaster Aqua Terra is a superb tribute to OMEGA’s rich maritime heritage. In this 38 mm model, the symmetrical case has been crafted from 18K Sedna™ gold, with diamonds on the bezel and a wave-edged design featured on the caseback. The purple jade dial is distinguished by a date window at 6H and a Small Seconds subdial featuring an 18K Sedna™ gold ring. The design is further complemented by 18K Sedna™ gold hands filled with white Super-LumiNova, as well as indexes that are shaped like sailboat hulls, with an iridescent mother-of-pearl inlay. Presented on a polished and brushed bracelet, this timepiece is powered by the OMEGA Co-Axial Master Chronometer calibre 8803, certified at the industry’s highest standard by the Swiss Federal Institute of Metrology (METAS).
