I have an electric clock that runs on one C-sized battery. It is made by the Uhrenfabrik Senden from Germany, but does say Made in France. Anyone out there with experience with this movement? I apply the 1.5 volts to it, but cannot get any movement at all from the magnetic-mechanical portion. If I move a gear with finger, the magnetic-mechanical portion will move back and forth. Just wondering what the most common issue is with these movements and if repairable. Thanks!
