ABSTRACT:
A chronometric indicator for a watch has concentric arrays of angularly equispaced electrodes and analog display segments. The electrodes are staggered relative to the display segments so that each electrode overlaps halves of two adjacent segments, so that by selective energization of the electrode and the segments any half can be optically activated. In addition a digital display is provided within the two annular arrays, with each digit segment of the display being connected to a respective analog segment. A common connection for this digital display can be energized simultaneously with any of the outer analog segments to cause the corresponding digit segment to glow. The overlapping arrays of electrodes and analog display segments are energized to indicate the hour and minute, and the digital display is energized to indicate the second.
