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 (clockwise), or
to tilt your watch from side to side a few times.To restore
your watch’s 46 hour power reserve, around 32 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 inuenced by the wearing conditions.
There is no stop of the crown at full winding.
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 ofcial 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.
During this operation, your watch will continue running, so
the time will not need to be re-set.
Important: Rapid date correction is impossible bet-
ween 8.30 p.m. and 11.30 p.m.
Chronograph function
Press the Start/Stop push-button (8) to start the chrono-
graph. Press the Start/Stop push-button (8) again to stop it.
The chronograph will resume if the Start/Stop push-button
(8) is pressed again (added times), or the two chronograph
hands (6and 7) will return to zero if push-button (9) is
pressed.
CARE AND MAINTENANCE
We would advise you to clean your watch regularly (except
for the leather strap) using a soft cloth and lukewarm
soapy water.After immersion in salt water, rinse the 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 elds.
We recommend you have your watch inspected every
3 to 4 years by your approved dealer or agent. 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
resistance 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).
