Abstract

A solid-state electronic watch having a battery-operated multi-digit display of the light-emitting diode type. In the Normal-mode of the watch, the display is quiescent to conserve power and prolong the life of the battery. A depressible Time-button switch is provided which, in the Time-mode, causes the display to present different functions of time, such as Hours-Minutes and Month-Date, depending on how the button is actuated by the user. A depressible Set-button switch is also provided. This switch, when repeatedly depressed and released by the user presents in sequence the individual readings to be set, such as Hours, Minutes and Date. The particular reading presented on the display by operation of the Set-button is advanced by actuating the Time-button. An automatic cut-off system is provided which in the Time-mode acts to discontinue the LED display immediately or shortly after the Time-button is released and in the Set-mode acts to discontinue the LED display shortly after the Set-button is released, whereby the watch always reverts to its Normal-mode regardless of how these buttons are operated.
