Abstract (en)

A multi-function analog electronic timepiece displays one of at least two different time data using the hour, minute and second hands, the displayed time data being changed upon external operation a switch. When the display mode is to be changed, a processor 5 of the timepiece calculates the time difference between the displayed time and the time to be displayed next, and automatically determines whether the hands are to be quickly driven in clockwise or counterclockwise directions to the destination time, in order to minimise the time required for changing the time data and to decrease the consumption of electric power required for driving by the reversible motor drive means 8.
