Chronograph - Tachymeter
Some Rotary Chronograph models feature a tachymeter function. This track
is usually located on the bezel of the watch or on the inner chapter ring on
the dial.
A tachymeter allows you to measure the average speed of an object moving
between 2 known points which can be one mile or kilometer away.
In order to do this, start the chronograph at the rst known point by
pressing Button ‘I’. When you have reached the second known point (one
mile or kilometer from the rst point), stop the chronograph by pressing
Button ‘I’ again.
The chronograph hand will now be pointing to a number on the tachymeter
scale indicating the average speed travelled between these points.
