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 29 mm 18K Sedna gold and stainless steel 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 Sedna gold. At the heart of this timepiece is the OMEGA Co-Axial Master Chronometer Calibre 8700, visible through the domed scratch-resistant sapphire crystal.
