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 25 mm 18K Sedna™ gold model features a diamond-paved bezel, white mother-of-pearl dial with diamond hour markers and scratch-resistant saphire crystal. The bracelet, hands, OMEGA logo, Constellation star and diamond holders are also in 18K Sedna™ gold.
At the heart of this timepiece is the OMEGA Calibre 4061, while the caseback is stamped with the Constellation Observatory medallion.
