Your watch
the Patravi t-Graph from carl F. Bucherer houses
a self-winding caliber cFB 1960 with a chrono-
graph and big date in its tonneau-shaped case
and features a very unusual power reserve
display. the high / low indication on the scale is
on a dial that moves clockwise as the power is
drawn. there is a hand on top of the dial that
also moves as the watch runs. thus the Patravi
t-Graph cunningly unites three useful functions.
