About this watch

The Omega Constellation Co-Axial 31 is a stunning blend of sophistication and mechanical excellence, featuring a unique combination of red gold and stainless steel that creates a striking contrast. The rich brown dial adds warmth to any outfit, while the round case (31mm diameter) sits comfortably on the wrist. The sapphire glass ensures scratch resistance, and the open case back showcases Omega's precision engineering.

This chronometer has undergone rigorous testing to ensure accuracy, with a power reserve of 50 hours and a frequency of 25,200 vibrations per hour. The Co-Axial escapement reduces friction between components, improving accuracy and extending the watch's lifespan. The Omega Constellation Co-Axial 31 provides an elegant display of time and date, with Dauphine hands gliding smoothly across the dial. Its water resistance rating of 100 meters makes it perfect for active lifestyles or spontaneous adventures.
