Omega Constellation Co-Axial Master Chronometer 28mm Steel Sedna Gold White Mother of Pearl Dial 131.25.28.60.55.001

The Omega Constellation is one of the most storied lines in Swiss watchmaking, tracing its origins to 1952 when Omega introduced a series of observatory-certified chronometers that redefined precision timekeeping for the wrist. Over the decades the Constellation evolved into a signature of refined elegance, recognised worldwide by its distinctive claws on the case, its polished star motif, and its unwavering dedication to horological accuracy. The current generation brings that heritage firmly into the twenty-first century, pairing classical design language with Omega's most advanced movement technology to create a watch that is as technically serious as it is visually captivating.

The reference 131.25.28.60.55.001 is sized at 28mm, a proportion that has long been considered the ideal expression of the Constellation's feminine silhouette. The case is constructed in a combination of polished steel and Omega's proprietary Sedna gold—an 18-carat rose-gold alloy formulated with copper and palladium to maintain its warm, blush-tinted colour far longer than conventional rose gold. That same Sedna gold frames the bezel, which is set with diamonds, adding a layer of fine-jewellery glamour without sacrificing the sportingly precise character that defines the Constellation family.

The dial is one of the watch's most captivating attributes. White mother of pearl, sourced for its natural iridescence, shifts between ivory, silver, and soft champagne tones depending on the angle of light—no two glances at the dial are ever quite the same. Diamonds are set across the dial to complement the diamond-set bezel, creating a cohesive jewellery aesthetic that elevates the piece well beyond an everyday timepiece. The overall effect is of something deeply considered: every element of the dial and case speaks to a singular vision of luxurious femininity.

Powering this Constellation is Omega's Co-Axial Master Chronometer movement, representing the pinnacle of what the brand currently offers in terms of movement engineering. The Co-Axial escapement, developed in collaboration with independent watchmaker George Daniels, dramatically reduces friction within the gear train, extending service intervals and improving long-term accuracy. Master Chronometer certification, issued by METAS—the Swiss Federal Institute of Metrology—requires the movement to pass eight stringent tests including performance in magnetic fields of up to 15,000 gauss, daily rate accuracy, and water resistance verification. This is not a decorative watch that happens to tell time; it is a certified precision instrument that happens to be spectacularly beautiful.

On the wrist, the 28mm diameter sits with understated confidence, complemented by the steel and Sedna gold bracelet whose two-tone finish ties the case, bezel, and dial into a unified whole. The bracelet's alternating polished and brushed link surfaces catch light in contrasting ways, reinforcing the interplay between jewellery sensibility and sporty architecture that is the Constellation's defining characteristic. The result is a watch that transitions effortlessly from a business meeting to a formal dinner.
