Setting instructions

Winding, time-setting and correction:
The winding, time-setting and correction crown (I) can be placed in
four positions A, B, C and D.
A: Screwed down against the case.
This is the normal position when the watch is being worn and
guarantees its water-resistance.
B: Unscrewed, winding position.
If the watch has not been worn for some time, wind it by rotating
the winding, time-setting and correction crown (I) through several
turns.
It is unnecessary to fully wind an automatic watch that is going to
be worn.
The winding, time-setting and correction crown (I) will not be locked
at the end of the winding cycle; the mechanism therefore cannot be
damaged.
Then screw the winding, time-setting and correction crown (I) back
to position A to ensure the water-resistance of the watch.

C: Date-setting position.
When the winding, time-setting and correction crown (I) is
unscrewed and pulled out to this position, rotation in the winding
direction enables the date display (7) to be adjusted.
NOTE: The calendar does not automatically account for the number
of days in a month. It will therefore have to be corrected manually for
months with fewer than 31 days.
If a rapid date correction is carried out between 10pm and midnight,
the next date change will not occur when the hands pass midnight.
Then push the winding, time-setting and correction crown (I) back
to position B and screw it down against the case in position A to
ensure the water-resistance of the watch.
D: Time-setting position.
When unscrewed and pulled out to this position, the winding, time-
setting and correction crown (I) can be turned to set the time.
If the time is being set in the afternoon, the hour hand (1) must have
completed more than one full revolution since the last date change
(7) to ensure that the date changes at midnight.
IMPORTANT: Do not pass the time at which the date changes by
turning the hands in an anticlockwise direction.
To ensure the date change system operates smoothly, it is preferable
not to adjust the date if the watch indicates between 10pm and 1am.
However there is no risk of damaging the mechanism if the month
is changed between this period of time.
Then push the winding, time-setting and correction crown (I) back
to position B and screw it down against the case in position A to
ensure the water-resistance of the watch.
