CALIbRES 1861, 1863, 3201
(fig. XV)
CALIbRES 3200, 3203
(fig. XVI)
CALIbRES 1866, 3604
(fig. XVII)
The crown has 2 positions:
Watch functions:
1.
Normal position (wearing position):
when the crown is positioned
against the case, the crown ensures that the watch is water-resistant.
Winding:
turn the crown forwards until it stops (DO NOT
OVERWIND).
Note:
do not wind the watch more often than is necessary. For
a watch that is worn all the time, a single winding each day will
ensure that it functions correctly.
2.
Time setting:
hours – minutes – seconds. Pull the crown out to
position 2. Turn the crown forwards or backwards. Synchronise the
seconds by pushing the crown back to position 1 to coincide with
a given time signal.
Note:
calibres 1861, 1863, 1866 and 3604 do not have a ’stop-
second’ mechanism. To synchronise, the crown should be gently
turned backwards and pressure maintained to stop the seconds
hand. Release when the display corresponds to the timing signal
and push crown back to position 1.
Chronograph functions:
•
Pusher A:
start – stop, start – stop, etc.
Timing to 1/6 of a second for up to 12 hours for the calibres 1861,
1863, 1866, 3604.
Timing to 1/8 of a second up to 30 minutes for the calibre 3200,
3203.
Timing to 1/8 of a second up to 12 hours for the calibre 3201.
•
Pusher b:
reset (after a stop).
Note:
resetting/zeroing of the sub dials must only be carried out after
the chronograph has stopped. Never push the chronograph’s two
pushers (A and B) simultaneously (calibres 3200, 3201).
Calibre 1866 – date and moon phase correction
–
Correcting the date (small counter at 12 o’clock):
press
corrector (C).
–
Correcting the moon phase:
press corrector (D) to move the disc
into the full-moon position. Then determine how many days have
elapsed since the last full moon (consult a calendar) and press the
corrector the equivalent number of times.
When the watch is running, the date and moon phase move forward
automatically.
Important:
avoid pressing correctors (C) and (D) (date and moon
phase) if the watch is displaying any time between 7 and 12 o’clock
(am or pm).
Do not set the date by moving the hour hand past midnight, since
this may desynchronise the date and moon phase indicators.
