Control and correction circuit for an electronic watch

摘要

A control and correction circuit for an electronic watch involving three push-buttons which are actuable to select and/or correct the information displayed by the watch. The push-buttons provide actuating signals to a delay device and to logic selection circuits which provide outputs to control the counters of the watch circuit. The delay device enables a secondary display to be displayed for a predetermined time after which the device returns to its initial state. During the predetermined time the information displayed may be corrected by actuation of the second or third push-button in which case the secondary display is held unitl the correction operation is complete before returning to its initial condition.
