The dramatic and enduring design of the OMEGA Constellation is characterised by its famous half-moon facets and “claws” on the case.
Standout features on this 29 mm model are the dial made from natural blue Aventurine stone and the shimmering leather strap in matching colour.
Crafted in 18K Sedna™ gold, it has a diamond-paved bezel and a date window at 6 o’clock. The hands, hour markers, OMEGA logo and Constellation star are in 18K Sedna™ gold.
At the heart of this timepiece is the OMEGA Co-Axial Master Chronometer Calibre 8701, visible through the domed scratch-resistant sapphire crystal.
