Abstract
An electronic timepiece indicates a change in one of the working parameters of the timepiece, such as the battery nearing its end of life, by changing a rest position of a user viewable indicating member. The timepiece includes a stepping motor driven by drive pulses produced from a timebase. The indicating member is rotated a certain amount by each step of the stepping motor and has two rest positions. The first indicates no change in the working parameter and the second indicates a change in the working parameter. The indicating member normally stops in the first rest position. A circuit responsive to a change in the working parameter causes an additional drive pulse to be applied to the motor, changing the normal stopping of the indicating member to the second rest position to indicate the changed working parameter.
