The Seamaster Aqua Terra is a superb tribute to OMEGA’s rich maritime heritage. One of four 34 mm watches celebrating the seasonal colours, this model has a symmetrical case in polished 18K Sedna™ Gold, a diamond-paved bezel, and a wave-edged design caseback. Complementing its fully snow-paved dial are 18K Sedna™ Gold hands filled with white Super-LumiNova, and 12 ruby hour markers. Presented on a matching 18K Sedna™ Gold bracelet with newly-designed beautifully rounded links, this timepiece is powered by the OMEGA Co-Axial Master Chronometer calibre 8807, certified at the industry’s highest standard by the Swiss Federal Institute of Metrology (METAS).
