Using your G-Shock Move GBD - 800 is easy. To turn on the LED backlight, just press the relevant button, and the white light will help you see the time clearly in the dark. Wear it for any daily activity or during your workouts. Since it's 200 - meter water - resistant, you can even wear it while swimming. But avoid exposing it to extreme heat or cold. When it comes to maintenance, clean the resin band and case with a soft, damp cloth regularly. This will keep your watch looking good and functioning well for a long time.
