The mechanical Swiss automatic clockwork of the calibre Valjoux 7750 makes the Model Railroad Chronograph to a literally „neutral“ authority.

To makes this visible, the Model Railroad Chronograph holds another feature, a case back made of sapphire crystal. Like the upper watch crystal it is made of an artificial, monocrystaline sapphire crystal with a hardness grade of 9. Thus it is scratch-resistant and shatter-proof.

Consquently you can observe the fine apparatus at its work: the swaying balance wheel together with the escapement wheel, the regulator, the fine gears. The free pivoted rotor uses every kinetc energy to subject the winding spring to tension.
