The grey dial boasts depth and nuance that change under different lighting conditions, creating a unique look every time you glance at it. The gem-set indexes add a touch of luxury, while the arrow hands provide clarity and precision. At the center of this masterpiece is the Omega Caliber 8800, a self-winding movement featuring the innovative Co-Axial escapement. This technology reduces friction, enhancing the movement's longevity and precision.

With a power reserve of 55 hours, you can confidently take this watch off for a weekend without worrying about it losing time. The sapphire glass adds an additional layer of protection, ensuring that the watch remains scratch-free over time.
