    • An electronic timepiece in which a higher frequency signal from a frequency standard is divided down to a lower frequency drive signal by a frequency converter. The drive signal is applied through a driver circuit to an electro-mechanical transducer which actuates time-representing members to indicate time. A control means is coupled to intermediate stages of the frequency converter and produces higher frequency drive signals. At least one contact plate made of flexible, electrically conductive material is adapted to be depressed from outside the watch case through a recess formed therein whereby the control means is connected to the driver circuit to apply the higher frequency drive signals to the electro-mechanical transducer thereby rapidly advancing the time-representing members.
    • 一种电子表,其中来自频率标准的较高频率信号由频率转换器分频到较低频率的驱动信号。 驱动信号通过驱动电路施加到机电换能器上,该机电传感器驱动时间表示构件以指示时间。 控制装置耦合到变频器的中间级并产生较高频率的驱动信号。 由柔性导电材料制成的至少一个接触板适于通过形成在其中的凹部从表壳的外侧凹陷,由此控制装置连接到驱动器电路以将较高频率的驱动信号施加到机电换能器 从而迅速推进时间代表成员。
