Constellation Steel - Sedna™ gold Master Chronometer 131.25.39.20.52.001

The dramatic and enduring design of the OMEGA Constellation is characterised by its famous half-moons, "claws" on the case and mono-rang bracelet. This 39 mm stainless steel and 18K Sedna™ gold model features a diamond-paved bezel, an opaline silvery dial with diamond hour-markers and a date window at the 6 o'clock position. The hands, OMEGA logo, Constellation star and diamond-holders on the dial are all in 18K Sedna™ gold. At the heart of this timepiece is the OMEGA Co-Axial Master Chronometer Calibre 8800, visible through the domed scratch-resistant sapphire crystal.
