Using your JULIUS women's wrist watch is easy. Simply put it on your wrist and adjust the band to a comfortable fit. To set the time, pull out the crown gently and turn it until you reach the correct time, then push it back in. This watch is 3 ATM water resistant, so it can handle splashes and short periods in water, but don't wear it while swimming or diving. Keep it away from extreme temperatures and magnetic fields as they can affect its performance. To maintain its shine, wipe the watch with a soft, dry cloth regularly. When the battery runs out after about 3 years, take it to a professional to replace the battery to avoid any damage.
