Using this men's watch is easy. Just fasten the buckle strap around your wrist and set the time using the crown. When setting the time, turn the crown gently. Since the watch is not waterproof, avoid wearing it when swimming, washing hands under running water, or in rainy weather. To keep your watch in good condition, clean the strap with a soft, dry cloth regularly. You can also wipe the dial and case to remove dust and fingerprints. Store the watch in a dry and cool place when not in use. If the watch stops working, it may be time to replace the quartz battery. You can take it to a professional watch repair shop for battery replacement.
