Produced in the early 1950's by Heuer,
for Abercrombie & Fitch,
the Auto-Graph includes
a three-register chronograph and a
unique complication -- a separate hand
(with a blue tip) that can be moved to a specific point to
mark a speed or a time.
The instructions (shown below), describe
the operation of the chronograph and also describe how this
hand may be used for a variety of purposes.
