  • Timepiece display which superimposes digits and graphics
    Patent number: 5748568
    Abstract: A watch or clock display shows hours as large digits and the minutes past the hour as the incremental filling of a familiar or regular figure. The digits and the partially filled figure are superimposed to make maximum use of the space available for the display.At the new hour, and for a predetermined number of minutes thereafter (say five or 7.5), only the hour number is shown in the center of the display. Then the first of successive segments of the figure are displayed. As the hour progresses, the figure becomes more nearly filled by increments.
