    Abstract: In a timepiece 100 having an antenna 3 and motors 4, each motor 4 includes a stator 41, a coil 42 magnetically connected to the stator 41, and a rotor magnet 431 disposed in a receiving part 411 of the stator 41. With respect to each motor 4 disposed in a predetermined range from the antenna 3, an individual antimagnetic plate 5 which is a belt-like antimagnetic plate configured to have a width equal to or greater than the diameter of the rotor magnet 431 and cover a portion of the motor 4 including the rotor magnet 431 is disposed.

    Abstract: A hand-moving mechanism configured to move a hand, the hand-moving mechanism including a stepping motor that includes a plurality of coils and that rotates a rotational shaft thereof in forward and reverse directions; a wheel train mechanism that includes a plurality of gears including one gear which is coupled to the rotational shaft of the stepping motor, and another gear which is coupled to the hand; and a motor driving control unit that individually controls energization to each coil to drive the stepping motor. A number of the coils to be simultaneously energized in a display hand-moving operation is different from a number of the coils to be simultaneously energized in a non-display hand-moving operation.

    Abstract: Disclosed is a stepping motor including a rotor, a stator which includes a rotor accommodating hole, a pair of outer notches to determine positions of saturated magnetic fluxes and inner notches disposed on an inner periphery of the stator around the rotor accommodating hole, the inner notches determining stably stationary positions of the rotor, and a coil block configured by a coil wound around a coil core which is magnetically coupled to the stator, and the outer notches are disposed on an outer periphery of the stator on opposite sides of the rotor accommodating hole. And a line that connects narrowest portions between the outer notches and the rotor accommodating hole and extends through a center of the rotor accommodating hole shifts by a predetermined angle from a line that extends through the center of the rotor accommodating hole and is orthogonal to an extending direction of the stator.
