ABSTRACT:
In an electronic timepiece having a central processing unit for processing current time and other data, and equipped with a crown and switch means coupled thereto for providing a correction signal comprising a pulse train of relatively high frequency, a bidirectional counter is provided for counting the correction signal pulses, with successive count totals in said counter being transferred in parallel form to be processed by the central processing unit. Processing of the high frequency correction pulses can thereby be performed even with the low maximum frequency which is generally available in an electronic timepiece for use as the clock signal to operate the central processing unit.
