ABSTRACT:
A stepping motor for a timepiece is constituted by a rotatable rotor magnet on an outer surface of which magnetic poles having different polarities are alternately formed, and two stator assemblies, each including a pair of stators opposing around the rotor magnet to have a gap and having stator magnetic pole portions, and an excitation coil for exciting the pair of stators, for supplying currents to the excitation coils to rotate the rotor magnet. The two stator assemblies are disposed to be separated by a predetermined distance in an axial direction of the rotor magnet, so that stator gap central lines of the two stator assemblies cross each other at an angle of 90.degree. when viewed from the axial direction.
