摘要： In an electronic watch, the content of the memory associated with the adjusting circuit of the division ratio of the frequency divider is modified at each correction of the display to compensate for the frequency error of the crystal oscillator and to thereby reduce the running error of the watch. Such electronic watches use a crystal oscillator whose frequency is not optimum. To compensate for the frequency variations due to manufacturing tolerances, age and temperature, correction circuits are incorporated into such watches. When an operator acts on a switch on the case of the watch to correct the time display indication, the content of the memory is modified to correct for the frequency error of the crystal oscillator.

摘要： An electronic digital watch including a device for enabling the correction of the minutes and seconds display. The device includes a delay circuit which only enables a correction to be effected if the push-button for correcting the display is actuated for a predetermined time, and means for resetting the seconds display to zero and, if the watch is slow, advancing the minutes display by one.

摘要： A set of digital indicators in an electronic display unit of a timepiece are actuated by driving pulses transmitted thereto through respective stages of a multistage frequency divider. A switching mchanism is manually operable to advance certain of these stages, independently of the driving pulses and at a faster rate, to adjust the display. A timer discriminates between short-term and long-term switch reversals to differentiate between a gating signal, giving passage to a train of high-rate stepping pulses, and (a) selection signals identifying an indicator to be stepped or (b) manually produced pulses for adjustment at a slower rate. A protective circuit may be inserted between the switching mechanism and the display-controlling circuitry for preventing the transmission of indication-modifying signals to the display unit in the absence of a special unblocking signal, generated separately, which trips an electronic relay such as a flip-flop into an off-normal condition for the emission of an enabling signal; the flip-flop may be automatically reset to normal, after a predetermined period, in the absence of a manually generated blocking signal. Stationary digital indicators, such as those registering the triggering time of an alarm circuit, may be similarly adjusted.
