Overview
The Omega Constellation Co-Axial Master Chronometer 41 in stainless steel with a black dial represents the contemporary pinnacle of the long-running Constellation line. Powered by Calibre 8900, it carries both COSC chronometer certification and the stricter Master Chronometer standard set by METAS, confirming exceptional precision and magnetic resistance. The 41 mm case positions it as a versatile dress watch suited to formal and smart-casual contexts alike.
History
The Constellation collection traces its origins to the 1950s, when Omega introduced it as a showcase for certified chronometric accuracy. The Co-Axial escapement, developed by George Daniels and adopted by Omega in the late 1990s, reduced friction and improved long-term rate stability across the line. The Master Chronometer designation, introduced in the mid-2010s, added METAS testing for magnetic resistance up to 15,000 gauss, and this reference — introduced in 2020 — brings that full suite of credentials to the 41 mm Constellation format. Among collectors, the combination of the Co-Axial escapement and Master Chronometer certification is regarded as a meaningful technical benchmark for a dress-oriented piece.
Notable points
- Calibre 8900 is both COSC-certified and METAS-certified as a Master Chronometer, resistant to magnetic fields up to 15,000 gauss.
- The Co-Axial escapement reduces the need for lubrication at the escapement level, contributing to longer service intervals.
- The 41 mm stainless steel case continues the Constellation's tradition of pairing robust construction with dress-watch proportions.
- The black dial offers strong legibility and a formal character that complements the polished case architecture.
- Introduced in 2020, the reference sits within Omega's current production lineup and reflects the brand's modern design language for the Constellation family.
