Since 1952, OMEGA Constellation watches have been inspired by the precise movement of the stars. A special model with an eye-catching meteorite dial takes the star theme one step further. This 41mm model features a stainless steel case and link bracelet, and features Constellation signatures such as polished claws, half-moon facets, and a black ceramic bezel with Roman numerals in liquid metal. They inherit certain characteristics. The beautiful dial is made from real iron meteorite and has a rhodium gray galvanic finish. The pattern of the meteorite varies depending on the model, and no two dials are the same. A date window at 6 o'clock, black PVD-coated hands, hour markers and a "Constellation" star complete the dial design. Equipped with Co-Axial Master Chronometer Caliber 8900. It can be seen through the sapphire crystal on the case back. This movement is certified by the Swiss Federal Institute for Metrology and Certification (METAS) and offers the highest level of precision, performance and anti-magnetic properties.
