Understanding the formula is easier than you might think. All watches use dots to represent the hour and the minutes. The dots will be lined up in either vertical or horizontal lines. If the lines are horizontal, the hour will have representative dots on the top line and minute dots on the bottom line. If the dots are vertical, the first row of dots will represent the hour and the second row will represent the minutes. The first row of dots might represent 8, 4, 2, and 1. The second row might represent 32, 16, 8, 4, 2, and 1. You simply add the glowing dots together in each row to read the time. For instance, if the dot for 8 is lit up and the dot for 2 is lit up on the top row, you add these two together. The hour is 10. Then, add the dots together that are glowing in the second row. If 16 and 2 are lit up, the minute is 18. By adding the dots together, you know that the time is 10:18.
