The dramatic and enduring design of the OMEGA Constellation is characterised by its famous half-moons, “claws” on the case and mono-rang bracelet. \n \nThis 36 mm stainless steel and 18K Sedna™ gold model features a bezel engraved with Roman numerals, a silk-embossed creamy silvery dial and a date window at the 6 o'clock position. The hands, OMEGA logo, Constellation star and indexes are all in 18K Sedna™ gold. \n \nAt the heart of this timepiece is the OMEGA Calibre 4564, which sits behind the brushed case back with its embossed Constellation Observatory medallion.
