Concept:

The hour digits from 1 to 12 are spaced equally along the circumference of a watch or clock dial. There are 5 divisions between the 2 numbers. A minute is represented by each section. Two hands, each of varying lengths, each with one end fixed at the dial's center. The minute hand is on the longer hand, while the hour hand is on the smaller hand. The minute hand advances more quickly than the hour hand. The second hand is a third hand that is also present.
