At the heart of this Omega beats the Co-Axial Calibre 2500, a movement that represents one of the most important breakthroughs in modern watchmaking. Developed around Dr. George Daniels’ revolutionary Co-Axial escapement, the calibre replaces the traditional Swiss lever system with a sophisticated three-level coaxial wheel architecture that separates the locking and impulse functions. This dramatically reduces internal friction, improves energy transmission, and delivers more stable timekeeping over longer intervals. With 27 jewels, a refined free-sprung balance, and a smooth 25,200 vph beat rate, the Calibre 2500 combines technical innovation with everyday reliability. It offers the precision and efficiency collectors expect from a high-grade Omega movement while embodying the spirit of one of horology’s greatest mechanical inventions — the Co-Axial escapement itself.

The diamonds on this factory-set Omega Constellation Co-Axial "Brushed Silver" Edition are truly exceptional. The bezel is adorned with 34 individually calibrated round brilliant diamonds, each selected for Internally Flawless clarity and perfectly matched for color, brilliance, and proportion — a level of gem-setting rarely seen at this price point. Their fire and precision elevate the watch from elegant to extraordinary. Adding to its desirability, this reference has long been sold out and discontinued, making well-preserved examples increasingly scarce. With its stunning diamond execution, Co-Axial movement, and rising collector demand, this model has become one of the most sought-after Constellations in the modern Omega lineup.
