Replacing a watch battery is simple. First, remove the back cover carefully using a small screwdriver or case opener. Take out the old battery and note its type. Insert the new battery in the same position, then close the back cover securely. Make sure the watch is working before wearing it.
To replace a watch battery easily, lay the watch face down on a soft cloth. Check the back if it snaps off, use a small flat tool or coin to pop it open; if it has screws, remove them with a small screwdriver. Take out the old battery using tweezers, put in the new one in the same position, and close the back tightly.
