The Omega Constellation Co‑Axial Master Chronometer 41mm Ref. 131.30.41.21.99.001 elevates the iconic dress watch collection by introducing a truly celestial element: a dial cut from genuine Muonionalusta meteorite, ensuring that every single timepiece is uniquely patterned and completely one of a kind . This striking 41mm stainless steel model frames its extra‑terrestrial dial with a black ceramic bezel featuring Liquidmetal™ Roman numerals, while the iconic Constellation claws and mono‑rang bracelet retain the collection’s instantly recognizable architecture . The rhodium‑grey meteorite dial displays the natural Widmanstätten patterns formed by cooling in space over billions of years, and is paired with black PVD‑treated hands, indexes, and the Constellation star for a stealthy, modern contrast, plus a practical date window at 6 o’clock . Beneath the surface lies Omega’s advanced Calibre 8900, an automatic Co‑Axial Master Chronometer movement certified by METAS for precision, performance, and resistance to magnetic fields of 15,000 gauss—far exceeding industry standards—while delivering a 60‑hour power reserve, visible through the transparent sapphire caseback . Water‑resistant to 50 metres and secured by a stainless steel bracelet with a foldover butterfly clasp, the 131.30.41.21.99.001 represents a rare intersection of cosmic history and cutting‑edge Swiss engineering, making it an exceptional choice for collectors who demand both technical mastery and an utterly unique watch . Key specifications: 41mm stainless steel case with black ceramic bezel; genuine iron meteorite dial; Omega Calibre 8900 automatic movement; 60‑hour power reserve; stainless steel bracelet; 50m water resistance; sapphire crystal front and exhibition back.
