Constellation Yellow gold Master Chronometer 131.50.39.20.02.002

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 39 mm 18K yellow gold model features a bezel engraved with Roman numerals, an opaline white silvery dial and a date window at the 6 o'clock position. The hands, OMEGA logo, Constellation star and indexes are all in 18K yellow gold. At the heart of this timepiece is the OMEGA Co-Axial Master Chronometer Calibre 8801, visible through the domed scratch-resistant sapphire crystal.
