Omega Constellation Co-Axial Master Chronometer 29mm Steel-Sedna Gold White Dial 131.25.29.20.55.001

The Omega Constellation is one of the most storied lines in Swiss watchmaking, introduced in 1952 as a symbol of precision and achievement. For over seven decades the Constellation has been synonymous with elegance, class, and technical authority, earning its distinctive claws — or "griffes" — on the case and the star motif as enduring hallmarks of the collection. Reference 131.25.29.20.55.001 represents the Constellation at its most refined, pairing advanced horological certification with unapologetically glamorous design details.

The 29mm case is sized for the contemporary woman who values understated wrist presence without sacrificing visual impact. Constructed from a harmonious blend of stainless steel and Sedna Gold — Omega's exclusive rose-toned gold alloy engineered to resist fading far longer than conventional rose gold — the case delivers both durability and warmth. The integrated steel and Sedna Gold bracelet flows seamlessly from the lugs, reinforcing the watch's cohesive, jewellery-like aesthetic.

The dial of reference 131.25.29.20.55.001 is a masterclass in restrained opulence. A white diamond-set surface catches and disperses light in all directions, while the diamond-set bezel frames the dial with an additional ring of brilliance. Together, these elements transform the watch from a precision instrument into a wearable object of art that transitions effortlessly from daytime sophistication to evening grandeur.

Powering this Constellation is a movement certified to Co-Axial Master Chronometer standards — the most stringent in-house certification Omega applies, validated by the Swiss Federal Institute of Metrology (METAS). Master Chronometer certification guarantees exceptional precision, magnetic resistance to fields of up to 15,000 gauss, and a high level of overall performance and finishing. This level of movement technology beneath a diamond-adorned dial underscores the Constellation's dual identity as both a luxury jewellery piece and a serious Swiss watch.

For collectors and first-time luxury watch buyers alike, the Omega Constellation 131.25.29.20.55.001 represents a rare intersection of gem-setting artistry and certified horological excellence.
