The crown at 3 o'clock is used to set the time and change modes. The crown at 9 o'clock is used to rotate the flange at the edge of the dial. The A button at approximately 2 o'clock starts and stops the chronograph function. The B button at approximately 4 o'clock resets the chronograph.
Lap Timer: When the watch is displaying normal time, press the right side crown to switch to chrono mode (the hour hand will indicate CHRONO). This watch measures lap times, press A to start timing the first lap. Press A again to stop the first lap and automatically start timing the second lap (the hour hand will move to indicate you're on the second lap), and so on. You can measure up to 20 laps this way. When you're fininshed timing laps, press the right side crown to see the best lap time. To reset the lap timer, hold down B for 2 seconds. To switch out of chrono and see the normal time, just press the right side crown in.
Chronongraph: To time an interval that is not a lap, just follow the above instructions, but instead of pressing A to stop the first lap, press B and the watch will show the elapsed time to the nearest 1/100th of a second. Hold B to reset.
Crown at 9 o'clock: This crown rotates the inner flange at the edge of the dial and is used to measure total race time (i.e. the total of all the laps). Simply rotate the crown until the the little start trinagle on the flange is aligned with the minute hand. This way, the total elapsed time can be read at any time, similarly to how a rotating bezel works.
To set the time: Ensure the watch is not in CHRONO mode, if so, press the right side crown in. At this time pull the right side crown out until you feel a click.The position the second hand moves to indicates what is currently being set. If the second hand is at 9 o'clock, you are setting am hours, press A repeatedly to set am hours. Then press B and the second hand will move to 6 o'clock, pressing A repeatedly will set the minutes. So on for year (11 o'clock), month (12 o'clock), and day (1 o'clock).
