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 and stainless steel, with a wave-edged design featured on the caseback.

The extra white mother-of-pearl dial is distinguished by a date window at 6H and a Small Seconds subdial featuring an 18K Sedna™ gold ring set with diamonds. The design is further complemented by 18K Sedna™ gold hands filled with white Super-LumiNova, as well as incremental diamond indexes that are set in 18K Sedna™ gold holders.

Presented on a polished and brushed bracelet, this timepiece is powered by the OMEGA Co-Axial Master Chronometer calibre 8802, certified at the industry’s highest standard by the Swiss Federal Institute of Metrology (METAS).
