STARTING THE WATCH
Your AVIATOR watch is battery-powered with power reserve up to 45 months. If you envisage
not wearing your AVIATOR watch for several weeks or months, we would advise you to store
it with the crown pulled out into position II. This cuts the electrical power supply to the motor,
consequently extending the battery life.
When wearing the watch, always return the crown to position 0 to ensure your watch
is water resistant.
DATE SETTING
First, set the time to 12 midnight in order to know the exact starting point of 24 hours. To
set the date on your AVIATOR watch, pull the crown to position I, turn the crown forward to
choose the correct date. Once date is set correctly, push back the crown to position 0. Now
you can set the correct time.
If a month has fewer than 31 days, you will need to set the date manually to the first day of
the following month.
TIME SETTING
Pull out the crown to position II. This will stop the movement to set the time accurately to the
second. It is the best to stop the movement as the seconds hand passes “60”. Now move the
minute hand a little bit beyond the time to be set. Then adjust the position of minute hand by
moving it backward to the correct minute stroke. This ensures that the minute hand starts to
move just when you restart the movement. To make the watch working again push the crown
back to position 0.

chronograph
Minute counter: The small hand in the counter indicates elapsed minutes. This sub-dial
indicates up to 30 minutes making two revolutions in one hour.
1/10 seconds counter: The small hand in the counter indicates elapsed 1/10 seconds. This
sub-dial makes one revolution in one second.
ADJUSTING THE CHRONOGRAPH HANDS TO ZERO POSITION
One or several chronograph hands might be not in their correct zero positions and have to
be adjusted (e.g., this may occur following a battery change)
Activate the corrective mode
1. Pull out the crown to position II (all chronograph hands are in their correct or incorrect
zero position).
2. Keep push-buttons A and B depressed simultaneously for at least 2 seconds (the

USING TACHYMETER
The tachymeter is the scale on the dial that enables the user to determine average speed or
hourly productivity rate based on an observation period of less than 60 seconds
Average speed
Use the chronograph to measure the time required to cover a kilometer or a mile. Once you
travel 1 km or mile, stop the chronograph and the position of central chronograph second
hand will indicate the average speed. If it stops at 30 seconds, the average speed is 120
km/h or 120 miles/h.
Hourly productivity rate
Measure the time require to produce 1 unit. If the chronograph is stopped at 30 seconds it
indicates 120, corresponding to an hourly productivity rate of 120 units.
USING TELEMETER
The Telemeter is the scale on the dial that enables the user to measure the distance to an
event that can be both seen and heard (e.g. a lightning bolt) using the speed of sound. The
user starts the chronograph at the instant the event is seen, and stops timing at the instant
the event is heard. The chronograph
