Electronic watch
Abstract:
An electronic watch includes a power generating mechanism; a battery that is charged with power generated by the power generating mechanism; hands that include a second hand; a driving source that rotates the hands; a driving circuit that drives the driving source with power supplied by the battery; and a control circuit that controls the driving circuit. The control circuit executes a first stopping operation for stopping the driving circuit and the control circuit in a power saving mode for suppressing power consumption and when a first determination time elapses without any power being generated by the power generating mechanism. The control circuit executes a second stopping operation for stopping the driving circuit and the control circuit in the power saving mode and when a second determination time elapses while a voltage of the battery is at a level equal to or lower than a predetermined level.
