ABSTRACT:
A timekeeping mechanism, such as a watch or a clock, is provided with a face and a single hand of predetermined length for designating both hours and minutes of time mounted for rotation at the center of the face. A first array of indicia, such as numbers corresponding to hours of time is arranged in an inner circular ring about the center of the face to delineate hourly time intervals. The radius of this inner ring is less than the length of the single hour and minute hand. In addition, indicia corresponding to minutes within an hour are arranged in an outer circular ring on the face in repetitive sets that each reside within the angular hourly intervals. The sets of indicia of minutes are located at a uniform distance from the center of the face corresponding to the length of the single hand. By visually following the indicia at which the single hand is aligned a user is able to ascertain the current time with the hour being designated by the aligned indicia in the inner ring and with the minutes of time past that hour being designated by the indicia in the outer ring.
