The OMEGA Constellation is a timeless icon, instantly recognisable by its signature half-moons, distinctive “claws” on the case, and elegant mono-rang bracelet. Its bold yet refined design has made it a symbol of enduring sophistication.
This 39 mm stainless steel model exudes understated luxury, featuring a bezel engraved with Roman numerals and a sun-brushed silvery dial. A date window at 6 o’clock complements the design, while the hands, OMEGA logo, Constellation star, and indexes are rendered in 18K white gold for a striking touch of refinement.
At its core, the watch is powered by the OMEGA Co-Axial Master Chronometer Calibre 8800, a movement celebrated for its precision, performance, and magnetic resistance. The calibre can be admired through the domed, scratch-resistant sapphire crystal, revealing the meticulous craftsmanship within.
