Abstract
In an electronic analog timepiece an automatic sequence of events determines the proper magnitude of a detection resistor which is used in series with the motor coil so as to determine whether in normal operation the rotor is rotated or not when driven. A detection resistor is used in series with motor coil but only after a fixed time has passed from initiation of detection current flow. The detection resistor is logically variable and selected automatically in accordance with the motor's mechanical load at the time of switching on the power source or releasing the analog timepiece from a resetting operation. The resistance is formed part of the integrated circuit.
