OMEGA 123.25.27.20.05.001 CONSTELLATION CO-AXIAL 27mm STEEL AND YELLOW GOLD - BRAND NEW

The Omega Constellation is one of the most storied lines in Swiss watchmaking, introduced in 1952 as the brand's flagship precision timepiece and the world's first watch to be officially certified as a chronometer by an independent observatory. Over the decades the Constellation evolved from a round-cased dress watch into the icon it is today, instantly recognizable by its clawed case, integrated bracelet, and bold medallion caseback. Reference 123.25.27.20.05.001 belongs to the modern Constellation Co-Axial family, a generation defined by Omega's proprietary escapement that dramatically reduces friction, extends service intervals, and delivers long-term accuracy superior to conventional lever escapements.

At 27mm in diameter, this reference is sized for the wrist that values refinement over statement. The stainless steel case is beautifully proportioned and finished with the characteristic Constellation faceting, while the integration of yellow gold into the two-tone bracelet lends warmth and a sense of quiet luxury. The bracelet itself flows seamlessly from the case, a design philosophy Omega has refined across multiple generations of the Constellation, creating a unified silhouette rather than a watch and strap as two separate objects.

The white mother-of-pearl dial is the visual heart of this piece. Mother-of-pearl dials are highly prized in fine watchmaking because no two are identical—each exhibits its own naturally occurring iridescence and pattern, meaning every reference 123.25.27.20.05.001 is subtly unique at the dial level. The luminous shimmer of the material shifts beautifully in changing light, from cool whites indoors to warm, almost creamy tones in natural sunlight, making this watch as captivating at a business lunch as it is at an evening event.

Encircling the dial, the diamond-set bezel elevates this Constellation from refined everyday watch to a genuine jewellery timepiece. Omega selects and sets diamonds to exacting standards, and the continuous ring of stones frames the mother-of-pearl dial with a brilliance that complements rather than overwhelms the understated elegance of the overall design. Paired with the yellow gold accents on the bracelet and case, the result is a thoroughly coherent aesthetic—warm, luminous, and unmistakably Omega.

Powering the watch is Omega's Co-Axial movement, the technology developed by master watchmaker George Daniels and adopted exclusively by Omega beginning in the late 1990s. The Co-Axial escapement is one of the most significant horological advances of the modern era, reducing lateral friction on the escapement wheel and allowing the watch to maintain its rate more consistently between services. For the owner, this means a watch that keeps exceptional time and requires less frequent intervention than competitors using traditional lever escapements.
