When you complete a calibrated distance of 1 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 kilometres 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 1 kilometre, so your average
speed is exactly 90 kilometres per hour.
