About this watch

The Omega Speedmaster Professional Missions Gemini IX is a stunning watch that combines heritage, functionality, and style.

At the heart of this timepiece lies the Omega caliber 1861, a hand-wound movement known for its reliability and precision.

The chronograph feature allows you to time events with precision, making it ideal for timing races or tracking daily activities. Constructed from high-quality stainless steel, the Gemini IX is built to withstand daily wear and tear. With a water resistance rating of 50 meters, it can handle splashes and brief immersions in water. This watch's versatility makes it suitable for both formal and casual occasions, thanks to its black dial and stainless steel finish. As part of the 'Moonwatch' line, this timepiece is a piece of space history, making it a collector's dream with its limited availability and historical significance.
