Constellation Steel - Sedna™ gold Master Chronometer 131.25.29.20.53.002

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 29 mm 18K Sedna™ gold and stainless steel model features a diamond-paved bezel, blue aventurine glass dial with diamond hour markers and a date window at the 6 o'clock position. The hands, OMEGA logo, Constellation star and diamond holders are also in 18K Sedna™ gold. At the heart of this timepiece is the OMEGA Co-Axial Master Chronometer Calibre 8700, visible through the domed scratch-resistant sapphire crystal.
