Using your JULIUS women's watch is a breeze. Simply put on the leather band and adjust it to fit your wrist comfortably. 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 it back in. Since it's 3 ATM water - resistant, it can handle light splashes like washing your hands, but avoid submerging it in water for long periods or in high - pressure situations like swimming. To keep your watch looking its best, clean the case and band regularly with a soft, dry cloth. When not in use, store it in a cool, dry place to prevent damage. The battery is designed to last for 3 years, but if you notice the watch running slow or stopping, it's time to replace the battery at a professional watch repair shop.
