摘要： In an analog electrical timepiece with a motor coil, when an external operating member is in a prescribed operating condition, the operating mode of the analog electrical timepiece is set to the data receive mode. Next, the analog timepiece generates a synchronization signal which is in synchronized to an external synchronization signal that is input from outside. Then, the analog electrical timepiece, when the operating mode is the data receive mode by the detection circuit, based on a synchronization signal and a data voltage signal that is a voltage signal induced around the motor coil by a data signal input from outside, generates and outputs a receive data.

摘要： A watch has a crown for manual time adjustment, a receiver for receiving current time update signals by radio transmission, an internal counter for counting the passage of time according to an internal oscillator, and time display hands. The watch preferably does not have a means for determining the position of its time display hands and therefore relies on user intervention for roughly correlating its time display hands to its internal counter. Preferably, the user begins a manual time correction operation when the second hand is at a predetermined position between 0-60 seconds. When the crown is pushed in, the seconds count value of the internal counter is reset to the predetermined position, and the watch waits for reception of a current time radio signal. When a radio signal is successfully received, the received seconds value is compared to the seconds count in the internal counter. If the time difference is within +30 seconds, the internal time is deemed to be advanced by the difference, and if the time difference is within −30 seconds, the internal time is deemed to be delayed by the difference. The received time data is written into the internal counter, and the time display hands are moved according to the deemed time difference.
摘要翻译：手表具有用于手动时间调整的表冠，用于通过无线电传输接收当前时间更新信号的接收器，用于根据内部振荡器计算时间流逝的内部计数器和时间显示手。手表最好不具有用于确定其时间显示手的位置的手段，因此依赖用户干预来将其时间显示手与其内部计数器大致相关联。优选地，当秒针在0-60秒之间的预定位置时，用户开始手动时间校正操作。当推入表冠时，内部计数器的秒计数值被复位到预定位置，并且手表等待接收当前时间无线电信号。当接收到无线电信号时，将接收到的秒数与内部计数器中的秒计数进行比较。如果时间差在+30秒之内，内部时间被认为是通过差值提前的，如果时间差在-30秒以内，则内部时间被认为被延迟了差值。接收的时间数据被写入内部计数器，并且根据所考虑的时间差移动时间显示手。

摘要： A timepiece includes pointers, motors for driving the pointers, a pointer position detector for detecting the positions of the pointers, a control unit, an electricity storage unit as a power supply, and a voltage detector for detecting the power supply voltage. The control unit controls the pointer position detection by means of the pointer position detector on the basis of the power supply voltage detected by the voltage detector. Therefore, the pointer position detector can be halted when the power supply voltage decreases to less than a specific voltage, and the pointer position detector can be driven while the power supply voltage is low.
