Constellation Co-Axial Master Chronometer 29mm

From the retailer listing

Since 1952, the OMEGA Constellation has been inspired by the precise movement of the stars. For this special model, that stellar theme is taken one step further, with the introduction of a captivating meteorite dial. The 29 mm watch is presented with a case and mono-rang bracelet created from 18K Sedna™ Gold, with signature Constellation features including the polished claws, half-moon facets, and a diamond-paved bezel. The astonishing dial is formed from a genuine piece of iron meteorite, which has been given a PVD Sedna™ Gold colour treatment. The natural pattern within the meteorite is unique to each model, meaning that no two dials are ever the same. It is completed with a date window at 6H, along with diamond hour markers, and a Constellation star in 18K Sedna™ Gold. Behind the sapphire crystal on the caseback, this impressive watch is driven by the Co-Axial Master Chronometer Calib
