ABSTRACT:
An electronic wristwatch with time and full calendar displays is programmed to uniquely display specially selected dates in the year using three manually operated input terminals. A terminal operation enables the memory to receive or erase special date data which is visible on the watch face at the time of selection. Month to month progression in the calendar display mode and day to day progression on the display in the write-in or erase mode is rapidly accomplished using two terminals.
