The dramatic and enduring design of the OMEGA Constellation is characterized by its famous half-moons, “claws” on the case and mono-rang bracelet.  This 39 mm stainless steel model features a bezel engraved with Roman numerals, a silk-embossed rhodium-grey dial and a date window at the 6 o'clock position. The hands, OMEGA logo, Constellation star and indexes are all in 18 karat Sedna™ gold.  At the heart of this timepiece is the OMEGA Co-Axial Master Chronometer Calibre 8800, visible through the domed scratch-resistant sapphire crystal.
