MEASURE TIME (CHRONOGRAPH)
The chronograph can be used to measure
time intervals for up to 12 hours exactly to 1/8
second. The time measured can be read using
the seconds, minutes and hours counters.
Start measuring time
1
using the P1 pusher.
The seconds counter is
in motion.
To stop measuring time,
2
press the P1 pusher again
and read where it stopped.

FLYBACK FUNCTION
The timepiece also has a precise chronograph
with a flyback switch. This flyback mechanism
allows one to quickly start a second time mea-
surement while one is in progress. That makes
it unnecessary to push the stop, reset and
start buttons.
While time measurement
1
is in progress, push the
P2 pusher to reset all the
counters to zero. The next
time measurement starts
automatically. In order to
put all the counters back
to zero after that, press
the P2 pusher with the
chronograph function
stopped.

TACHYMETER FUNCTION

The tachymeter is used to determine speed.
It measures the elapsed time needed to cover
a specific distance. The distance covered must
be known so that the time can be stopped at
an exact time to determine the exact speed.
Start the tachymeter
1
function by using the P1
pusher. The seconds
counter is in motion.
To stop measuring time,
2
press the P1 pusher again.
The seconds counter stops
immediately.
3 Read the average speed
by optical extension of the
seconds counter.
