If the hands of your watch have come off after replacing the battery, it could be due to a few different issues. Here are some possible causes and solutions:

1. Improper installation: If the hands were not properly aligned when the battery was replaced, it could cause them to come off when the watch is turned face-up. Make sure that the hands are properly aligned and securely fastened to the watch movement before reassembling the watch.
2. Loose or damaged hands: If the hands were loose or damaged before the battery replacement, they may have come off when the watch was turned face-up. Check the hands for any damage or wear and if necessary, replace them with new hands.
3. Damaged watch movement: If the watch movement was damaged during the battery replacement process, it could cause the hands to come off when the watch is turned face-up. Have the watch movement inspected by a professional watch repair technician.
4. Incorrect battery size: If the incorrect battery size was used to replace the old battery, it could cause the hands to come off when the watch is turned face-up. Make sure you are using the correct battery size and type for your watch.
5. Incorrectly set the hands: During the battery replacement, if the hands were moved or set incorrectly, it could cause them to come off when the watch is turned face-up. Double check that the hands are set to the correct time and position.
