ABSTRACT:
An electro-magnetic motor for a timepiece wherein the stator is formed of two pole pieces contacting the ends of a core traversing a coil. Both ends of the core and one end of each pole piece have notched portions with cross sections of the notched portions of the core being at least equal to the cross section of core as it passes through the coil and cross sections of the notched portions of the pole pieces being substantially equal to the cross sections of the notched portions of the core, so that the notched portions do not produce an increase in the resistance to the passage of magnetic flux through the core and pole pieces.
