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 yellow gold and stainless steel model features a bezel with engraved Roman numerals, 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 yellow gold. At the heart of this timepiece is the OMEGA Co-Axial Master Chronometer Calibre 8700, visible through the domed scratch-resistant sapphire crystal. The Omega Constellation 18.104.22.168.53.001 women watch has an automatic movement with Steel/Gold bracelet.
