    摘要: An analog quartz timepiece having a manually operated external control member, and a correction signal generation circuit controlled by the external control member to generate low speed and high speed correction signals when the external control member is actuated for a short period of time and for a predetermined time interval, respectively, by which a stepping motor is driven at a selected speed to perform time correction. The timepiece alo includes a click mechanism operative to shift an hours hand step-wise from any optional position without affecting a minutes hand and a seconds hand. The timepiece further includes a seconds zero-reset mechanism operative to reset the seconds hand to zero.
