Abstract

A correction circuit for an electronic timepiece is provided wherein a divider stage can be corrected without effecting correction of any other digit of the electronic timepiece to be corrected. The electronic timepiece includes a quartz crystal oscillator circuit for producing a high frequency time standard signal, a divider circuit including a plurality of divider stages adapted to receive said high frequency timekeeping signals, certain of the divider stages being adapted to produce low frequency timekeeping signals in response to said high frequency timekeeping signals, and display elements associated with said certain divider stages for displaying the time counted thereby in response to said timekeeping signals applied thereto. The electronic timepiece includes a correction circuit including a portion intermediate a divider stage to be corrected and the next divider stage for inhibiting the carry signal from the divider stage to be corrected, whereby the next divider stage is not advanced by the carry signal of the divider stage to be corrected. In one embodiment, an inhibit circuit is corrected to receive the corrected carry signal from divider stage to be corrected and the carry signal from the next-previous divider stage and adapted to inhibit the transmission of that portion of the corrected carry signal representative of a carry due to correction to the next divider stage.
