Start: To start the chronograph, press the start/stop button.
Flyback: You can start recording a new time immediately, even when the chronograph
is running. Simply depress the reset/flyback button fully, as far as it will go. All three
chronograph hands are reset to zero, and a new measurement is started as soon as
the button is released.
Stop: To stop the running chronograph, press the start/stop button.
Reset: Depress the reset/flyback button fully, as far as it will go. This will reset all the
chronograph hands to zero.
Aggregate time recording: You can add stop times together by pressing the start/
stop button again after the first measurement instead of the reset/flyback button.

When you complete a calibrated distance of one kilometre, you can read your average
speed directly on the tachymeter scale. Activate the chronograph as you pass your
starting point and stop it at the end of the measured distance. You can now read the
average speed in kilometers per hour from the position of the chronograph seconds
hand on the tachymeter scale. Please note that any period over one minute in length
is invalid.
Example: It takes 40 seconds to drive one kilometre, so your average speed is exactly
90 kilometres per hour.
