For the friends of American railroads or British railways there is the Model Railroad Chronograph with mph scale on the tachymeter and display of the weekdays in English.

The tachymeter shows two scales for high and low speeds. They are adapted to the conversion factor according to km-miles and cover speeds between 250 and 15 mph as well as between 50 and 1 mph.

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.
