Omega Constellation Co-Axial Master Chronometer 28mm Steel Sedna Gold Silver Dial 131.20.28.60.52.001

The Omega Constellation is one of watchmaking's most enduring icons, introduced in 1952 as a line purpose-built to celebrate Omega's chronometric achievements at the Swiss Official Chronometer Testing Institute. Decades on, the Constellation has evolved into a hallmark of refined femininity and technical excellence, and the 28mm Co-Axial Master Chronometer generation represents the pinnacle of that evolution. Reference 131.20.28.60.52.001 sits at the heart of this legacy, marrying Omega's advanced movement technology with a design language that is unmistakably elegant.

At 28mm, the case is sized for the wrist that appreciates understated luxury without sacrificing presence. The case itself is constructed in a combination of polished steel and Omega's proprietary Sedna Gold — a rose-toned 18k gold alloy formulated to resist fading and maintain its warm blush hue over a lifetime of wear. This two-material approach gives the watch a sophisticated two-tone character that reads equally well with casual dress and formal attire, making 131.20.28.60.52.001 a genuinely versatile companion.

The silver dial is set with diamonds, adding a layer of brilliance that elevates the watch from a precision instrument to a genuine jewellery piece. The iconic Constellation "claws" — the four angular lugs that have defined the model since the 1960s revival — frame the dial and anchor the integrated bracelet seamlessly into the case. The Sedna Gold bezel frames the dial with a warm glow that contrasts beautifully against the cool polish of the steel elements, and the matching steel-and-Sedna Gold bracelet flows organically from the case for a unified silhouette.

Beneath the dial, this reference is powered by Omega's Co-Axial Master Chronometer movement, a designation that represents a dual certification of excellence. Co-Axial escapement technology reduces friction and extends service intervals compared with traditional lever escapements, while Master Chronometer certification — awarded by METAS, the Swiss Federal Institute of Metrology — confirms that the movement meets the industry's most stringent standards for precision, magnetic resistance, and performance across a battery of eight tests. Buyers can wear this watch confident that its accuracy is held to the highest verifiable benchmark in Swiss watchmaking.

For collectors and first-time luxury buyers alike, the Omega Constellation 131.20.28.60.52.001 represents exceptional value at its intersection of gem-set beauty and certified mechanical performance. The combination of Sedna Gold, diamonds, and Master Chronometer engineering is rarely found at this case size, making this reference a standout choice in the 28mm luxury segment. Its brand-new condition means you receive the watch exactly as Omega intended, with all associated manufacturer assurances intact.
