About this watch

The Omega Speedmaster Professional Missions Gemini VI is a masterpiece of luxury watchmaking.

With a power reserve of 48 hours and a frequency of 21,600 vibrations per hour, it keeps time admirably. The small seconds, hours, and minutes hands offer a traditional analog display that harkens back to the original Speedmaster models.
