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 28 mm 18K yellow gold and stainless steel model features a diamond-paved bezel, sun-brushed champagne dial with diamond hour markers and scratch-resistant sapphire crystal. The hands, OMEGA logo, Constellation star and diamond holders are also in 18K yellow gold.
At the heart of this timepiece is the OMEGA Calibre 4061, while the caseback is stamped with the Constellation Observatory medallion.
