1. If you do it yourself, prepare the tools.
2. First use a screwdriver to open the bottom cover on the side of the handle, then use small tweezers to remove the old battery and replace it with a new battery.
3. It is best to wear gloves when changing the battery to prevent the dust on your hands from getting into the watch and affecting the normal operation.
4. If the watch is purchased in a formal mall or building, you can go to the place of purchase to repair or replace the battery during the warranty period.
5. If the warranty period has expired or there is no warranty, you can also go to a professional watch repair shop, and ask the staff there to replace the battery while purchasing the battery.
