A timing device utilizes hybrid power to drive a movement of the timing device, the hybrid power supply functioning as an auxiliary unit to deliver power to an electro-magnetically driving unit through an automatic control unit manipulated by a mechanical energy storage status detection unit to produce mechanical energy in time to prevent the movement from stopping; a main spring barrel or a potential difference weight of the kinetic energy storage unit being driven to further drive a wheel chain of the timing device and automatically suspend driving upon the completion of winding the wheel train.
