Abstract
Motor-driven movement for timepieces wherein stator block core is formed in ring-shape with a magnetic material of a rounded bar, magnetic poles formed at both core ends are disposed as directed radially inward of the core and rotary shaft of minute hand wheel of output gear train meshing with a rotor disposed between the poles is radially displaced from the center of the core to the side opposite the magnetic poles, whereby internal space of the ring-shaped core having a coil wound thereon is efficiently utilized for arranging all internal components substantially within dimensions of the coil and minimizing the entire size of the movement.
