We'll start by looking at the device to determine what caused the screen damage. Sometimes a screen can get chipped or cracked from being dropped or just from everyday use. Other times, the battery can swell due to the gases produced from overcharging (this may be caused by a faulty battery or charger), which can crack the screen. In this case, you'd need a battery replacement, too. Either way, our trusted associates can remove the damaged screen and replace the glass screen on your Apple Watch in-store.
