Abstract
A clock movement for table or wall clocks, the movement including at least a synchronous motor section and analog display section, the synchronous motor section adapted to receive a fixed cycle pulse signal to rotatably drive analog indicating hands at a fixed speed. The synchronous motor section includes an elongated C-shaped stator disposed within a case and a rotor rotatably supported by the case and rotated between stator poles of the stator, the rotor having a rotor pinion engaged by a first reduction wheel, the rotation of the first reduction wheel being transmitted to the analog indicating hands through a time indicating gear train, both of the first reduction wheel and time indicating gear train being disposed within the case. The gear train from the rotor to the time indicating gear train is disposed on a straight or curved line extending from the central stator axis to provide an elongated configuration to the movement case.
