About this watch

The Omega Constellation Co-Axial 31 Red Gold / MOP is a masterpiece of luxury watchmaking. Its round 31mm case in luxurious red gold exudes warmth and richness, while the iridescent mother-of-pearl dial creates a visual spectacle that's hard to ignore. The Dauphine hands glide smoothly over the dial, ensuring time is both visible and beautifully presented. At its heart lies the Omega Caliber 8521, a self-winding movement designed for precision and reliability. With automatic winding in both directions and a power reserve of 50 hours, this watch is built to withstand daily wear and tear. Certified as a chronometer, it guarantees exceptional accuracy, making it a testament to Omega's commitment to quality and precision.
