ABSTRACT:
An electronic timepiece which has storage means storing the positions of the pointers and controls the drive of the pointers.
A transfer means acts to transfer data between a first pointer position storage means and a second pointer position storage means. A drive-stopping means activates the transfer means. At this time, the transfer means transfers the positional data stored in the first pointer position storage means to the second pointer position storage means. If the output from a voltage comparator means indicates that the supply voltage exceeds a threshold voltage value set by a threshold voltage value-setting means, then a starting control means transfers the data stored in the second pointer position storage means to the first pointer position storage means.
