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 yellow gold model features a bezel engraved with Roman numerals, a sun-brushed champagne dial with diamond indexes and a date window at the 6 o'clock position. The hands, OMEGA logo, Constellation star and diamond holders are all in 18K yellow gold. At the heart of this timepiece is the OMEGA Co-Axial Master Chronometer Calibre 8800, visible through the domed scratch-resistant sapphire crystal. The Omega Constellation 18.104.22.168.58.001 men watch has an automatic movement with Steel/Gold bracelet.
