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 bezel engraved with Roman numerals, crystal white silvery dial and a date window at the 6 o’clock position. The hands, OMEGA logo, Constellation star and indexes 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.
