Omega Constellation Co-Axial Master Chronometer

The Omega Constellation Co-Axial Master Chronometer embodies the collection's longstanding tradition of precision, elegance, and distinctive design. Crafted in stainless steel, this 39mm model features the Constellation's signature half-moon case facets and four characteristic claws positioned along the bezel, design elements that have defined the collection's identity for decades. Its rhodium-grey dial is distinguished by an intricate silk-embossed texture, complemented by blackened hands, applied hour markers, and the iconic Constellation star. A bezel engraved with blackened Roman numerals and a coordinating grey alligator leather strap complete the watch's sophisticated, contemporary appearance.

Powering the watch is Omega's self-winding Co-Axial Master Chronometer Calibre 8800, certified by the Swiss Federal Institute of Metrology (METAS) for exceptional precision, performance, and resistance to magnetic fields of up to 15,000 gauss. The movement provides a 55-hour power reserve and features Omega's signature Co-Axial escapement and decorative Geneva waves in arabesque, visible through the transparent sapphire caseback. Combining advanced mechanical engineering with a refined aesthetic, this Constellation offers a modern expression of one of Omega's most recognizable collections.

History and Collecting

Introduced in 1952, the Omega Constellation was conceived as a flagship chronometer collection, celebrating the manufacture's achievements in precision timekeeping. Its name and celestial symbolism reference Omega's success in observatory chronometer competitions, where the brand established numerous records throughout the early 20th century. In 1982, the collection underwent a significant transformation with the introduction of the Constellation Manhattan, whose distinctive claws, integrated design, and Roman numeral bezel established a new visual identity. The contemporary 39mm Constellation preserves these recognizable elements while incorporating Omega's modern Master Chronometer technology, connecting more than seven decades of watchmaking heritage with present-day innovation.
