Using your JULIUS women's wrist watch is a breeze. Simply put on the leather band and adjust it to fit your wrist comfortably. Since it has 3 ATM water resistance, it can handle light splashes like washing your hands, but don't take it for a swim. For maintenance, keep it away from extreme temperatures and magnetic fields. Wipe the watch case and band gently with a soft cloth regularly to keep it looking its best. When the battery runs out after about 3 years, take it to a professional to replace the battery.
