ABSTRACT:
An all electronic watch has an analog minute and hour display comprising two concentric circles of radially disposed LEDs which are energized sequentially in a manner to simulate the movement of the minute and hour hands of a mechanical watch, and a centrally located digital display of date. The circuitry for energizing the LEDs of the analog minute and hour display and the digital date display comprise up-down counters. Amendment of time in a forward direction or in a backward direction is effected by switches actuated by the crown of the watch to feed fast pulses to the counters to operate the counters in a forward direction or in a backward direction as desired. The crown has two operational positions and is rotatable selectively in opposite directions in the manner of a mechanical watch to effect time and date amendment forwardly or backwardly.
