OMEGA 131.25.29.20.99.001 CONSTELLATION 29 mm, steel ‑ Sedna™ gold on steel ‑ Sedna™ g
Product Overview
Since 1952, the Omega "Constellation" has drawn inspiration from the precise movements of the stars. This special model, featuring an eye-catching meteorite dial, takes the theme of stars a step further. With a case diameter of 29mm, this model is crafted from stainless steel and 18K Sedna™ gold, and includes a link bracelet. It retains the signature features of the "Constellation," such as polished claws, half-moon facets, and a bezel set with pavé diamonds. The beautiful dial is made from genuine iron meteorite and is treated with a rhodium gray galvanic finish. The patterns of the meteorite vary by model, ensuring that no two dials are the same. A date window at 6 o'clock, diamond indexes, and the 18K Sedna™ gold "Constellation" star complete the dial design. It is powered by the Co-Axial Master Chronometer Caliber 8700, visible through the sapphire crystal case back. This movement offers the highest level of precision, performance, and magnetic resistance, certified by the Swiss Federal Institute of Metrology (METAS).
