The 303 M
is a model railroad chronograph
The tachymeter of this chronograph is matched to a model railway. Thus, the speed of a fast model ICE can be measured as exact as that of a historic steam locomotive. A sympathetic additional function, that makes this watch an original and personal property of every true model railroader.
