ABSTRACT OF THE DISCLOSURE A solid-state electronic timepiece in which the output of a high-frequency time base is divided down to produce low frequency timing pulses that are applied to a display actuator adapted to selectively control a multi-digit electro-optic display to present the "time-of-day" and "seconds" as well as other aspects of time information such as calendar date and month. The actuator also serves to supply roll-over pulses to advance the display at a rapid rate for setting purposes. In order to selectively render the display effective in any one of the sev- eral aspects or in the setting mode therefor by means of a single manually-operated coding key, a mode selector is provided which is responsive to the key and operates in conjunction with the display actuator. Code signals produced by the key are decoded by the logic system to produce command sig- nals that are fed to the actuator to cause the dis- play to operate in the aspect mode to present the desired aspect or to operate in the setting mode. -1-
