Using your Fossil ES5364 Harlow watch is a breeze. Just put on the brown leather strap around your wrist and start wearing it. To set the time, gently pull out the crown on the side of the watch and turn it until you reach the correct time. Then push the crown back in. As for care, avoid exposing the watch to extreme temperatures or strong chemicals. If it gets dirty, use a soft, dry cloth to wipe it clean. When you're swimming or washing hands, you don't have to worry as it's water-resistant up to 30 meters, but don't go diving with it. Also, check the leather strap regularly for any signs of wear and tear. If you notice the strap getting loose or damaged, it's a good idea to take it to a professional for repair or replacement.
