Omega Constellation Co-Axial Master Chronometer 28mm Steel Yellow Gold Green Dial 131.25.28.60.99.002

The Omega Constellation is one of the most storied collections in the Swiss watchmaking world, tracing its origins to 1952 when Omega introduced it as a showcase for its finest certified chronometer movements. Over seven decades the Constellation has evolved from a quietly elegant dress watch into a bold, jewellery-influenced icon recognisable worldwide by its distinctive clawed case, integrated bracelet, and the star motif inherited from its earliest certified predecessors. Reference 131.25.28.60.99.002 represents the collection at its most glamorous and technically accomplished.

At 28mm in diameter, this reference is sized with precision for the modern woman who appreciates a watch that sits gracefully on the wrist without overpowering it. The case is constructed in a harmonious pairing of stainless steel and polished yellow gold, a combination Omega has long mastered to strike the perfect balance between durability and luxury. The alternating textures and metals give the case a dynamic, light-catching quality that elevates it well beyond a simple timekeeping instrument.

The green diamond dial is the most arresting feature of this reference. Rich and deep in colour, the dial is set with diamond hour markers that catch the light with every movement of the wrist, creating an interplay between the gem-set indices and the vivid green background. The yellow gold diamond-set bezel reinforces the jewellery sensibility of the piece, framing the dial with a continuous row of brilliant-cut diamonds and linking the case to the two-tone yellow gold and steel bracelet in a seamless, architecturally considered design.

Powering the watch is Omega's Co-Axial Master Chronometer movement, the brand's highest standard of in-house mechanical excellence. Master Chronometer certification, issued jointly by Omega and the Swiss Federal Institute of Metrology (METAS), confirms that the movement meets eight stringent tests covering precision, magnetic resistance, and performance across real-world conditions. This level of certified performance is rarely found in a watch that also functions as a piece of fine jewellery, making reference 131.25.28.60.99.002 genuinely exceptional.

On the wrist, the 28mm Constellation delivers a presence that is confidently luxurious without being ostentatious. The integrated yellow gold and steel bracelet flows naturally from the case, wearing comfortably throughout the day and catching the light in a way that invites compliments. Whether paired with formal attire or elevated everyday dress, this watch transitions effortlessly across occasions.
