Abstract
An electronic timepiece having a multi-digit display of time data and a plurality of frequency divider circuits which generates time data, which comprises operation testing and time correcting means including at least two test terminals, and also a manually operable selecting switch and a manually operable correcting switch. The electronic timepiece also comprises a circuit means which is arranged such that varying combinations of logic level voltages applied to the test terminals can be utilized to test various modes of operation of the frequency divider circuits, a part of such testing being accomplished in conjunction with a signal of relatively high frequency applied to a terminal of one of the manually operable switches.
