Special Functions
P1: Starting and stopping of the chronograph: A single press starts the direct-drive seconds hand (D). After
one minute, the minutes-counter hand (E) jumps one minute, in contrast to the hours counter (F), which
is dragging (thus indicating which half hour is in progress). A second press stops the chronograph
function.
P2: Resetting the chronograph to zero. Pressing the push-piece once returns the three chronograph hands
(direct-drive seconds (D), minutes-counter (E), hours counter (F)) to zero. The chronograph must be
stopped before this function can be used (see P1).
Tachymeter display and functions
The tachymetric scale (H) serves to measure the average speed of a vehicle, for example, over a given
distance (a kilometre or a mile), and the time elapsed. Start the chronograph function at the beginning of the
first kilometre or mile. Stop the chronograph when you reach the end of the chosen distance. The tip of the
direct-drive seconds hand (D) shows the average speed of the vehicle.
N.B.: Setting 2 (G) cannot be changed manually between 8 p.m. and 2 a.m. Any alteration made during this
period may damage the movement.
