Using your Principe Prive Kuuga mechanical watch is simple. Just wind it up manually at first to get it started, and then it will keep ticking as long as you wear it. The auto - winding function means it will wind itself as your wrist moves. When it comes to cleaning, use a soft, dry cloth to gently wipe the watch face and band. Avoid getting the watch wet as much as possible, and if it does get wet, dry it immediately. Store it in a cool, dry place when you're not wearing it. This will help keep your watch in top condition for years to come.
