Constellation Sedna™ gold Diamonds Watch 131.55.28.60.55.001

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 Sedna™ gold model features a diamond-paved bezel, white mother-of-pearl dial with diamond hour markers and scratch-resistant sapphire 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.
