The dramatic and enduring design of the OMEGA Constellation is characterised by its famous half-moon facets and claws on the case. This 29mm yellow gold model features a bezel with engraved Roman numerals, blue aventurine glass 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 blue leather strap. At the heart of this timepiece is the OMEGA Co-Axial Master Chronometer Calibre 8701, visible through the domed scratch-resistant sapphire crystal.
