* 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 jorney ( up to
the maxinum 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 45 seconds,
the average hourly speed during the journey will be about 80 km.
