This is an old problem, but maybe this will help someone changing a battery on a Casio. Many Casio watches must be "zeroed out" by putting an pointed tweezers between the back of the battery and the AC terminal off to the side of the battery. On my old Casio Telememo 50, the AC terminal is in a very small hole just above the battery. On the Baby G force, it was in a wider opening, way at the edge of the watch. It has something to do with resetting the watches circuitry so it will operate again. Good luck!

Springs? No springs in a solar powered electronic watch. If there is anything wrong with it, return it to Casio for repair.

depends on your use of watches and the environment you tend to be in. If you are somewhere that allows you to see whether there it is day or night, than using 12 hr setting will work just fine. However if you're in a place that keeps you secluded and you are not able to determine whether it is day or night than 24 hr. setting will help you keep track of not just the time, but whether it is day or night.

To set time and date, you must in "Time Keeping Mode" (display day, date & time) then press and hold the left-up button until it start flashing. To set press right-down button, to go next setting press left-down button.

To toggle between 12-hour to 24-hour, again, must in "Time Keeping Mode" then press right-down button.
