Aqua Terra 150M Seamaster Steel - Sedna™ gold Master Chronometer 220.20.41.21.02.001

The Seamaster Aqua Terra is a superb tribute to OMEGA’s rich maritime heritage. This 41mm model has a symmetrical polished-brushed case in stainless steel and 18K Sedna™ gold, and a screw-in caseback with a wave-edged design. The silvery sun-brushed dial has a horizontal “teak” pattern inspired by the wooden decks of luxury sailboats, which is a signature feature of these models. Keeping track of the hours, minutes and seconds are facetted hands in 18K Sedna™ gold, filled with white Super-LumiNova. Days are marked by a date window at 6 o'clock. Matching perfectly with the case is a stainless steel and 18K Sedna™ gold bracelet. Powering the watch is OMEGA’s Master Chronometer calibre 8900 - certified at the industry’s highest level by the Swiss Federal Institute of Metrology (METAS).
