Constellation Yellow gold Master Chronometer 131.63.41.21.01.001

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 18K yellow gold model features a polished black ceramic bezel with Roman numerals in Ceragold™, 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 in 18K yellow gold. Presented on a black leather strap with rubber lining, this timepiece is driven by the OMEGA Co-Axial Master Chronometer Calibre 8901, visible through the domed scratch-resistant sapphire crystal.
