  • Patent number: 4370068
    Abstract: An hour and minute display for an electronic chronometer includes a plurality of first indicators positioned in spaced relation about the perimeter of a closed geometric figure. The first indicators are actuatable to indicate the hour. A plurality of second indicators are positioned about a closed geometric figure adjacent the first indicator. The second indicators are selectively actuatable to indicate minutes past the hour in 5-minute increments. Also positioned adjacent the first indicators is a third indicator capable of being actuated to selectively indicate increments of one, two, three or four minutes past the displayed 5-minute increment. The first, second and third indicators are preferably driven by digital counter circuits commonly employed in conventional electronic chronometers.
