    Yes it is a gravity driven clock with electric winding by the sound of it. Many turret clocks are wound by the same basic principal.
    Nick, lots to learn, late starter.

    Indeed. The balance can spin but the hands won't move unless the weight is falling.

    One common term for this type of movement is "self winding".

    It is not an electric clock at all but it does have an electric device built in to wind it

    Car clocks from the early days were of this type as well.
