ABSTRACT:
A chronometric indicator has a multidigit display each of whose digits is formed by a plurality of individually energizable digit segments having respective digit-segment connections and having a common digit-display connection so that simultaneous energization of the common connection with any of the digit-segment connections will optically activiate the respective digit segments. An annular array of sixty angularly equispaced analog display segments surrounds the multidigit display and has an analog-segment connection for each part and inner and outer rings subdividing the analog display segments into inner and outer parts. Simultaneous energization of the inner or outer rings and one of the analog-segment connections will optically activate the corresponding inner or outer part. Each of the digit-display connections is connected to a respective one of the analog display segments. A sequencer is connected to the rings and all of the connections and in the first part of a three-part cycle energized the outer ring and one of the analog segment connections to display the minute, in the second part it energizes the ring and one of the analog segment connections to display the hour, and in the third part energizes the common connection of the multidigit display and several of the analog segment connections to form a digital display of the second.
