Abstract
A multi-function LED wristwatch in which all the required functions may be performed with the use of only two push button switches. These switches are time demand for displaying hours, minutes and seconds and date demand for alternatively displaying day of month, month of year, AM or PM of time, and day of week. They also perform all the setting functions for these displays and through sequential button depression and digital logic circuits, five of the functions, namely hours, minutes, day of the month, month of the year, and day of the week may be set independently.
