Self-winding split-seconds chronograph
Operating instructions2
Watch functions (calibre 3600)
The crown has 2 positions:
1. Normal position (wearing position): when the crown is posi-
tioned against the case, the crown ensures that the watch is water-
resistant.
2. Time setting: hours – minutes – seconds. Pull the crown out to
position 2. The seconds hand will stop. Turn the crown forwards or
backwards. Synchronise the seconds by pushing the crown back to
position 1 to coincide with a given time signal.
Watch functions (calibre 3612)
The crown has 3 positions:
1. Normal position (wearing position): when the crown is posi-
tioned against the case, the crown ensures that the watch is water-
resistant.
2. Correcting the date: pull the crown out to position 2, turn the
crown backwards, then push the crown back to position 1.
NB: the date cannot be corrected between 9 pm and 12.30 am.
3. Time setting: hours – minutes – seconds. Pull the crown out to
position 3. The seconds hand will stop. Turn the crown forwards or
backwards. Synchronise the seconds by pushing the crown back to
position 1 to coincide with a given time signal.
Occasional winding: if the watch has not been worn for 45 hours
(calibre 3600) or 55 hours (calibre 3612) or more, wind it up with the
crown in position 1.
Chronograph functions:
• Pusher A: start - stop, start - stop, etc.

Operating instructions2
• Pusher B: reset (after a stop).
Note: the chronograph must always be stopped before the zero
resetting function is used. Never push the chronograph’s two pushers
(A and B) simultaneously (calibre 3612).
Chronograph functions with split-seconds:
The split-seconds function allows split times to be recorded whilst the
chronograph is running.
1. Start the chronograph by pressing pusher (A) (start).
2. To record a split time, press pusher (C). The split-seconds hand (D)
stops, indicating the split time, whilst the chronograph continues
running.
NB: the split time should be read immediately, since the chrono-
graph totalisers for hours (G), minutes (E) and seconds (F) continue
to measure the elapsed time.
For calibre 3600 only: whilst the chronograph is running, do not
leave the split-seconds hand (D) stopped any longer than is neces-
sary to read the split time, otherwise the functioning of the split-
seconds mechanism may be affected.
3. Press pusher (C) for the split-seconds hand to catch up with the
chronograph seconds hand (F).
4. To record a new split time, start from step 2 above.
5. Press pusher (A) to stop the chronograph.
6. Press pusher (B) to reset.
NB: the split-seconds hand (D) must have caught up with the
chronograph seconds hand (F) as explained in step 3 before the
chronograph mechanism is reset/zeroed.
