PURPOSE:To change easily a clockwise timepiece to a counterclockwise timepiece by switching the polarity of a stator magnetic pole to the opposite polarity. CONSTITUTION:The polarity of a magnetic pole of a stator is switched to the opposite polarity, that is to say, the N pole and the S pole are switched to the S pole and the N pole, respectively, by a driving part of an analog quartz timepiece which has placed a rotor between the magnetic poles of the stator energized by a driving coil. In this way, a clockwise timepiece can be changed easily to a counterclockwise timepiece without changing the internal circuit. |
