Abstract
A digital electronic timepiece which comprises an oscillator circuit providing a relatively high frequency signal, a frequency divider dividing down the relatively high frequency signal to provide a first low frequency signal representative of the count of one second and a second low frequency signal higher in frequency than the first low frequency signal and representative of the count less than one second, a first counter responsive to the first low frequency signal to provide time and calendar information signals; and an additional data signal a second counter responsive to the second low frequency signal to provide output signals representative of the count less than one second, first display means for displaying time and calendar data in response to the time and calendar information signals, second display means composed of a plurality of display segments for displaying data representative of the count less than one second in step-wise fashion in response to the output signals from the second counter, said display segments serving as means for displaying additional data, and switching means for enabling said second display means to display said additional data.
