About this watch

The Omega Constellation Co-Axial 27 embodies the essence of luxury watchmaking with its exquisite design, advanced movement, and durable construction.

With a power reserve of 50 hours and a frequency of 25,200 vibrations per hour, this movement is designed for longevity and reliability. The watch boasts a water resistance rating of 100 meters, making it suitable for everyday wear.
