Aqua Terra Shades Seamaster Sedna™ gold Master Chronometer 220.55.38.20.09.001

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 is crafted in polished 18K Sedna™ Gold, with a diamond-paved bezel, conical crown, and a wave-edged caseback with flat sapphire crystal. The sun-brushed and lacquered dial is CVD-treated and presented in a sandstone colour, featuring an applied circular date window in 18K Sedna™ Gold, and grey coloured transfers. 18K Sedna™ Gold has also been used for the facetted hands, as well as the hour-markers, which are shaped like sailboat hulls and filled with white Super-LumiNova. Set on an 18K Sedna™ Gold bracelet with a butterfly clasp and redesigned rounded links, this watch is powered by OMEGA’s Co-Axial Master Chronometer calibre 8801, certified at the industry’s highest standard by the Swiss Federal Institute of Metrology (METAS).
