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 stainless steel model features a bezel engraved with Roman numerals, pearled mother-of-pearl 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 in 18K white gold.
At the heart of this timepiece is the OMEGA Co-Axial Master Chronometer Calibre 8700, visible through the domed scratch-resistant sapphire crystal.
