|Two tachymeter scales cover speeds between 400 and 25 km/h as well as between 80 and 2 km/h. You can grasp the speed of a superfast intercity express as reliably as that of a slow shunting engine.
Almost all measurements are shut off in less than 60 seconds. Merely in extremely slow journey less than 6 km/h you let the clock go on. The tachy indicates in 1 km / h steps the speed to 2 km/h. These figures are colored.
These double scale offers a good compromise between precision of the measurement results, length of the measuring sections and lasting of the measuring processes.
The lengths of the measuring segments are printed in an inch/cm table at the back of the watch.
