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.
