The Chronograph has many parts, some move constantly, others move only when activated, so it may look like your watch is not working, but indeed it is. A Chronograph consists of one main dial and three subdials or smaller dials. There is a subdial located at the 3 o'clock position which indicates military (24-hour) time. There is another subdial located at the 6 o'clock position which is the seconds hand. The seconds hand measures 60 seconds and moves constantly. At 9 o'clock there is a third subdial which is the stopwatch subdial. The stopwatch hand is at the 12 o'clock position and has an arrow at the top. The stopwatch is started by pressing the button on the right side of the outside case at the 2 o'clock position, once. The stopwatch will measure 60 minutes on the stopwatch from the moment it is started. It is stopped by the same button and reset by the button on the right side of the outside case which is located at the 4 o'clock position. When you reset the stopwatch, the stopwatch hand will reset at the 12 o'clock position.
