2. Annual calendar: pull the crown out to position 2. Turn the
crown forwards to change the date or backwards to change the
month. Push the crown back to position 1.
Note: the day following 28 or 29 February (depending on
whether it is a leap year), the date needs to be adjusted by one
or two days (crown in position 2). Ideally, the date should be
adjusted after setting the time. When correcting the date between
midnight and 10am, the effort required for the first jump is
slightly greater than for the others.
3. Time setting: hours – minutes – seconds. Pull the crown out to
position 3, the seconds hand will stop. Turn the crown backwards
only. Synchronise the seconds by pushing the crown back to
position 1 to coincide with a given time signal.
Nb: when changing the date backwards in time setting mode,
ê
it is necessary to wind the hands back to 2 pm to ensure the date
changes. Make sure the month has been set prior to setting the
time.
CALIbRES 8602, 8612 (fig. III)
The crown has 3 positions:
1. Normal position (wearing position): when the crown is
positioned against the case, the crown ensures that the watch is
water-resistant.
Occasional winding: if the watch has not been worn for 55 hours
or more, wind it up with the crown in position 1.
2. Correcting the date: pull the crown out to position 2. Turn the
crown forwards to change the date or backwards to change the day.
Push the crown back to position 1.
Nb: do not quit setting mode if the displays (day and date) are not
ê
properly centred in their windows.

water-resistant.
Occasional winding: if the watch has not been worn for
48 hours or more (calibres 8520, 8521: 50 hours; calibre 1120:
44 hours), wind it up with the crown in position 1.
2. Correcting the date: pull the crown out to position 2, turn the
crown backwards (forwards for calibres 2520, 8520 and 8521)
and push it back to position 1.
For calibre 2610 only: date adjustment is made by instantaneous
jumps.
Nb: date-setting is not recommended between 8pm and 2am.
