USE
WINDING
Crown in position
I
, not pulled out
Manual winding is necessary if you have not worn your
watch for some considerable period of time. To restart
it, you only need to turn the crown a few times (clock-
wise), or to tilt your watch from side to side a few times.
To restore your watch’s 65 hours power reserve, around
40 turns of the crown (forward) are required.
When wearing your watch, the automatic device winds it
every time you move your wrist.
Notes
The accuracy may be influenced by the wearing conditions.
There is no stop of the crown at full winding.
Tachymeter
Start the chronograph and stop it once a distance of 1 km
has been covered by pressing the Start/Stop push-button
(
10
). The chronograph hand will be pointing to a numeral
on the tachymeter scale (
9
), indicating the speed in km/h.
Pulsometer
When starting the chronograph, count 30 consecutive
pulse beats and then stop the timing by pressing the start/
stop button (
10
).
The chronograph hand points to a digit on the pulsometer
scale (
9
). This digit represents the pulse rate per minute.
SETTING THE TIME
Crown in position
II
, pulled out
Pull the crown out to position II carefully; the seconds hand
(
3
) will stop. Turn the crown forwards or backwards to
set the desired time, and then push it back into the rest
position
I
.
Once the hour hand passes the 12 o’clock position, you
can see if it is indicating midnight (date will change) or
midday (date will not change).
Advice on how to synchronise your watch
To synchronise the seconds hand (
3
) with an official time
signal (radio/TV/Internet), pull out the crown to position
II
;
the seconds hand will stop. At the signal, push the crown
back into the rest position I.
RAPID DATE CORRECTION
Press the corrector as many time as needed (
5
), to move
the disc forward until the desired date (
4
) is displayed. Dur-
ing this operation, your watch will continue running, so the
time will not need to be re-set.
Important: Please do not use the rapid date correc-
tion between 8:30 p.m. and 11.30 p.m.
CHRONOGRAPH FUNCTION
Press the Start/Stop push-button (
10
) to start the chron-
ograph. Press the Start/Stop push-button (
10
) again to
stop it. The chronograph will resume if the Start/Stop
push-button (
10
) is pressed again (added times), or the
three chronograph hands (
6
,
7
and
8
) will return to zero if
push-button (
11
) is pressed.
CARE AND MAINTENANCE
We would advise you to clean your watch regularly
(except for the leather strap) using a soft cloth and luke-
warm soapy water. After immersion in salt water, rinse your
watch in fresh water and leave it to dry completely.
Ensure that you do not leave it in places subject to great
temperature and humidity variations, in intense sunlight or
near strong magnetic fields.
We recommend you have your watch inspected every
3 to 4 years. For an irreproachable maintenance service
and to ensure the warranty remains valid, always approach
an approved dealer or agent.
WATER RESISTANCE PRECAUTIONS
Your watch is water resistant but, following a shock, it may
lose its water resistance without you realising. Water resist-
ance must be checked up during its scheduled inspection.
Important: In the event of failure of your watch,
entrust it only to an approved dealer or agent (see
the warranty).
