ELECTRIC MOTOR FOR A TIMEPIECE

A small synchronous motor is provided with a stator winding wound around a stator core. Conversion efficiency is improved by setting the ratio of the coil length (L) to the thickness between the center of the core and the outer most periphery of the coil (R) to be L/R to 40.
