To set the time, use the screw - down crown. Just unscrew it gently and turn it to adjust the hours, minutes, and date. The watch has GMT and dual - time functions, which are great for travelers. You can switch between different time zones easily. When it comes to water resistance, it can handle up to 200 meters, so you can wear it while swimming or snorkeling.

Try to keep it away from strong magnetic fields as it can affect the accuracy of the watch. And remember, the watch has a 50 - hour power reserve, so if you don't wear it for a while, give it a few gentle shakes to wind it up.
