Correcting the day: pull the crown out to position 2, turn the
crown backwards, then push the crown back to position 1.
Note: in the quick mode, the date is changed in two steps. Check
that the date hand (calibre 3888) or day disc plate (calibre 3890)
is centred after the change has been made.
Date-setting is not recommended between 10pm and 2am. During
this time lapse and under certain conditions, a safety element can
prevent these corrective functions from working.
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.
Chronograph functions:
• Pusher A: start – stop, start – stop, etc.
Timing to 1/8th of a second for up to 12 hours or up to 7 days for
calibres 3888 and 3890.
• 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 (calibres 3301, 3303 and 3313).
