<p>An electronic timepiece, wherein, when a winder switch (8) is pulled up, a switch signal preparation means (9) outputs a signal (RS) indicating the pulling up, a control means (13) receives the signal (RS) and starts a timing with a timer (13a), the control means (13), when receiving a signal (HS) output from a power generation detection means (12) within a timing period, outputs a signal (CS) indicating the detection when detecting the power generating operation of a power generation means (10) , a micro pulse preparation means (7), based on the signal (CS), prepares micro pulses having a pulse width of such a degree that a motor (5) is not driven and outputs the pulses to a motor drive circuit (4), the motor drive circuit (4), based on the micro pulses, flows a micro current to a coil (4a) for driving the motor (5), and a variation in the micro current is detected by an external device so as to confirm the presence or absence of the power generating operation.</p> |
