An electronic watch generator in which the wrist of the wearer is turned until the angle of inclination of the watch and, thus, the rotor, is sufficient to enable gravity to overcome a magnetic latching force which holds the rotor in place. The rotor is a pendulum with gravity and subsequent acceleration activating its position change to generate a voltage due to relative movement between coils located on the stator and the magnetic pole pieces on the rotor. The magnetic latching force holds the rotor against rotation until the desired angle of inclination of the wrist is sufficient to provide rapid acceleration and, accordingly, a large voltage output. The voltage generated by this action is stored in a rechargeable storage cell and is utilized to operate the watch module and display.
