The dramatic and enduring design of the OMEGA Constellation is characterised by its famous half-moons, as well as the “claws” on the side of the case.
This 41 mm stainless steel model features a polished black ceramic bezel with Roman numerals in Liquidmetal™, a sun-brushed black dial and a date window at the 6 o'clock position. The hands, OMEGA logo, Constellation star and facetted indexes are all rhodium-plated.
Presented on a black leather strap with rubber lining, this timepiece is driven by the OMEGA Co-Axial Master Chronometer Calibre 8900, visible through the domed scratch-resistant sapphire crystal.
