Using this watch is easy. Just fasten the buckle strap around your wrist. When you set the time, gently pull out the crown and turn it to adjust. Since it's not waterproof, avoid wearing it when swimming or washing hands. To keep it looking good, clean the strap with a soft, dry cloth regularly. For the case and dial, you can use a mild cleaner and a soft brush. Store it in a dry place when not in use to prevent damage.
