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 Moonshine™ Gold and features a radiant diamond-paved bezel. The iridescent coloured mother-of-pearl dial has been given a distinctive Supernova pattern through laser engraving, while other details include a date window at 6H, 18K Moonshine™ Gold hands and star, and diamond hour markers in 18K Moonshine™ 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.
