Aqua Terra 150M Seamaster Steel - Sedna™ gold Master Chronometer 220.20.38.20.02.001

The Seamaster Aqua Terra is a superb tribute to OMEGA’s rich maritime heritage. In this 38mm model, the symmetrical case has been crafted from 18K Sedna™ gold and stainless steel, with a wave-edged design featured on the back. The silvery dial is distinguished by a horizontal “teak” pattern which is inspired by the wooden decks of luxury sailboats. There is also a date window at 6 o'clock and 18K Sedna™ gold hands and indexes filled with white Super-LumiNova. Presented on a polished and brushed bracelet made from 18K Sedna™ gold and stainless steel, this certified chronometer is powered by the OMEGA Master Chronometer calibre 8800, certified at the industry’s highest standard by the Swiss Federal Institute of Metrology (METAS).
