Online stopwatch tool area The stopwatch uses the isochronism of the pendulum to control the rotation of the pointer to keep time. On the front of it is a large dial with a small dial above it. The second hand rotates along the large dial and the minute hand rotates along the small dial. The sum of the times pointed by the minute and second hands is the measured time interval. There is a crown directly above the watch with a button. Turn the button to wind up the clockwork, which is what makes the stopwatch move. Press the button with your thumb and the stopwatch will start timing; press the button again and the stopwatch will stop and take a reading; press it again and the stopwatch will return to zero and prepare for the next time.
