Abstract
A mode selection switch is provided for selectively enabling a time information display, namely, a timepiece mode, and a calculator operation, namely, a calculator mode. Function keys for the calculator operation are adapted to select a desired time information section, for example, the date information section, the hour information section, and the minute information section during the timepiece mode, thereby resetting the time information stored in the selected information section to zero. Thereafter, a desired value is introduced into the selected information section through numeral keys for the calculator operation.
