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 model, with case and bracelet in stainless steel, features indexes and applied elements in 18K white gold, set against a striking celestial blue dial. To give the bezel an extra pop of colour, OMEGA has highlighted the engraved Roman numerals in the same pastel shade. At the heart of this timepiece is the OMEGA Calibre 4061. Turning the watch over reveals a Constellation Observatory medallion stamped on the caseback.
