Aqua Terra Shades Seamaster Steel - Sedna™ gold Master Chronometer 220.20.38.20.09.001

The Seamaster Aqua Terra is a superb tribute to OMEGA’s rich ocean heritage and combines classic design with contemporary inspiration. This 38 mm model, crafted in polished stainless steel and 18K Sedna™ Gold, has a conical crown and wave-edged caseback with flat sapphire crystal. The sun-brushed and lacquered PVD-treated linen dial features a circular date window at 6 o’clock ringed in 18K Sedna™ Gold. OMEGA has also used 18K Sedna™ Gold for the facetted hands and distinctive hour-markers, which are shaped like sailboat hulls and filled with white Super-LumiNova. It is set on a matching stainless steel and 18K Sedna™ Gold bracelet and powered by OMEGA’s Co-Axial Master Chronometer calibre 8800, certified at the industry’s highest standard by the Swiss Federal Institute of Metrology (METAS).
