Abstract
A digital watch including a clocking signal generator is disclosed wherein a control circuit provides phasing signals for multiplexing data representing seconds, minutes, hours, and data information in successive cycles to a visual display panel. In the normal mode of operation of the watch, minutes and hours are displayed. The watch further includes circuitry for selectively displaying seconds and date information as well as for setting the hours, minutes, and date. The aforementioned functions require the utilization of only three functional switches which may be incorporated into a stem of the watch. By selectively closing and opening one switch, as for example, pushing in and releasing the stem, seconds information is first displayed and then the date information is momentarily displayed for a predetermined interval after which the watch returns to a normal mode of operation of displaying hours and minutes.
