发明名称 Electronic timepiece with time zone change features
摘要 An electronic timepiece with a digital display includes a timekeeping circuit which stores the present time in a specific geographical region A, a keyboard adapted to introduce a time difference between two geographical regions A and B, and a calculation circuit which executes a time zone change operation by means of the contents of the timekeeping circuit and the time difference introduced via the keyboard, thereby loading the timekeeping circuit with the results of the time zone change operation instead of the previously stored horological information. When one desires to obtain a time zone change in another region C, the time difference is introduced into the timekeeping circuit storing the present time in the time zone B.
