Constellation Sedna™ gold Master Chronometer 131.55.29.20.60.001

With precision inspired by the stars, the iconic OMEGA Constellation is characterised by its famous case with half-moon facets, and the polished claws that grip to the sides. This 29 mm model is crafted in 18K Sedna™ Gold and features a radiant diamond-paved bezel. The PVD purple dial has been given a distinctive Supernova pattern through electrochemical etching, while other details include a date window at 6H, 18K Sedna™ Gold hands and star, and diamond hour markers in 18K Sedna™ Gold holders. The watch is presented on a signature mono-rang bracelet with easy comfort-adjustment, and is powered by the OMEGA Co-Axial Master Chronometer Calibre 8701, which is visible through the sapphire crystal caseback.
