A world watch has an hour hand and a minute hand for usual time indication, a plurality of symbols disposed on a dial to represent areas having respective time differences, an area including hand for specifying one of the areas by indicating one of the symbols, a local time indicating hand for indicating the local time of the specified area at least in hours, and a date indicating hand for indicating a date of the specified area. The world watch comprises counters for counting the numbers of driving signals used for driving the area indicating hand and local time indicating hand, respectively; and a drive controlling circuit for generating, when the count of at least one of the counters reaches a predetermined value, a driving signal for driving the date indicating hand in a normal or reverse turning direction based on a judgment whether the predetermined value has been described by an increase in the count or by a decrease in the count. With this arrangement, the standard time and date of an optical area are correctly and easily displayed.
