Constellation Co-Axial Master Chronometer 29

The Omega Constellation Co-Axial Master Chronometer 29 (ref. 131.10.29.20.55.001) is a compact dress watch built around a 29 mm stainless steel case and a mother-of-pearl dial set with diamond indexes. It belongs to the storied Constellation line, one of Omega's longest-running families of elegant timepieces. The combination of Co-Axial escapement technology and METAS-certified Master Chronometer status places it at the intersection of horological rigour and refined aesthetics.

The Constellation collection traces its origins to the 1950s, when Omega introduced it as a showcase for precision and polished design. The Co-Axial Master Chronometer generation of the Constellation was unveiled in 2018, bringing the line's movements up to the demanding METAS certification standard, which tests for accuracy, magnetic resistance, and water resistance. The 29 mm reference was conceived to serve wearers who prefer a more discreet case diameter without sacrificing the technical achievements of the broader Constellation family. It has remained in production since its introduction, reflecting sustained collector and retail interest in refined small-case dress watches.
