* TACHYMETER
The tachymeter is the device which measures the speed of an automobile. Knowing is how
many seconds the car covers a distance of 1km, the meter can measure the approximate
average speed per hour during a journey (up to the maximum measurable range of
tachymeter is 60 seconds.)
If the chronograph is started at the same time as measurement, and stopped after 1 km,
the average speed per hour can be determined according to the position of the second
hand. If the car covers the distance of 1km in 45second, the average hourly speed during
the journey will be about 80 km.
