Constellation Steel Master Chronometer 131.18.36.20.61.001

The dramatic and enduring design of the OMEGA Constellation is characterised by its famous half-moon facets and “claws” on the case. This 36 mm stainless steel model features a polished bezel set with 38 diamonds, a burgundy PVD treated dial with sun-brushed finish and a date window at the 6 o'clock position. The hands, OMEGA logo, Constellation star and indexes are all in 18K white gold. On this Constellation, the famous mono-rang bracelet is replaced with a leather strap in the same colour as the dial. At the heart of this timepiece is the OMEGA Co-Axial Master Chronometer Calibre 8800, visible through the scratch-resistant sapphire crystal.
