778, an electronic watch that stores electric charge generated by a power generating means in a charge storage member and further increases or decreases the voltage to serve as a power source, is equipped with a hand movement control means that changes the hand movement state in accordance with the voltage increase/decrease ratio. By doing so, it is possible to know the charging rate of the charge storage member in detail just by knowing the step-up/down multiplication factor without installing a special voltage detection means.Furthermore, since the charging rate is indicated by the hand movement status, there is no need to use an extra indicator. It is no longer necessary and can be distinguished at a glance.
