ABSTRACT:
An electronic timepiece having a pulse generator producing a high frequency time standard signal, a divider circuit formed from a plurality of series-connected divider stages for producing low frequency timing signals in response to said time standard signal and a device for displaying time in response to said timing signals, is provided with a correction circuit disposed in said divider circuit. The correction circuit enables the use of a new method and apparatus for providing a correction signal to the divider stages counting seconds to reset the divider stages to zero seconds during use of the watch, to thereby correct the accuracy of the second display.
