ABSTRACT:
An electronic timepiece including a stepping motor and a time-indicating hand moved in a stepwise manner by the stepping motor for indicating time. During normal operation the time-indicating hand moves at a normal periodic rate. When operating conditions such as a low battery cause the stepping motor to not rotate, correcting pulses are applied to the stepping motor to supply additional energy to it to cause it to rotate. Additionally, the correcting pulses cause the rotor, and the time-indicating hand to rotate at a rate different from the normal periodic rate to alert the timepiece user that some condition exists tending to cause non-rotation of the stepping motor.
