The dramatic and enduring design of the OMEGA Constellation is characterised by its famous half-moon facets and “claws” on the case. This 29 mm 18K yellow gold model features a diamond-paved bezel, pearled mother-of-pearl dial with diamond hour markers and a date window at the 6 o'clock position. The hands, OMEGA logo, Constellation star and diamond holders are also in 18K yellow gold. Replacing the famous mono-rang bracelet is a burgundy strap in shimmering leather. At the heart of this timepiece is the OMEGA Co-Axial Master Chronometer Calibre 8701, visible through the domed scratch-resistant sapphire crystal.
