Constellation Steel - yellow gold Master Chronometer 131.23.41.21.10.001

The dramatic and enduring design of the OMEGA Constellation is characterised by its famous half-moon facets and “claws” on the case. This 41 mm model, in stainless steel and 18K Yellow gold, features a black polished ceramic bezel ring with Roman numerals filled with OMEGA Ceragold™. It has a sun-brushed green dial with gradient effect and a date window at the 6 o'clock position. The hands, OMEGA logo, Constellation star and indexes are also in 18K Yellow gold. Replacing the famous mono-rang bracelet is a green leather strap with rubber lining. At the heart of this timepiece is the OMEGA Co-Axial Master Chronometer Calibre 8900, visible through the scratch-resistant sapphire crystal.
