Winding the watch
If the watch were to stop, 30 turns (clockwise)
of the crown in position
A
suffice to wind the
movement fully. The movements of the wearer's
wrist will activate the automatic system and keep
the watch running.
Warning : the watch must be worn to activate the
automatic system. If not, the automatic system
will not work and the watch will stop after about
two days.
Setting the time
Pull the crown to position
B
. You may now set
the time by winding in either direction without
risk of damaging the movement. Recommendation :
make sure to set the time precisely by carefully
moving the hands forward to the time desired.
Warning : Be careful not to confuse noon and
midnight, due to the change of date (calibre 2121
only).
Rapid date correction procedure
(calibre 2121 only)
Warning : The date correction sector is between
10 o'clock and midnight (see figure).
If the date indicated does not correspond, pull
the crown to position
B
.
Turn the crown clockwise to move the hand to
12.10 o'clock. The date moves forward by one
day.
Turn the crown anti-clockwise to return the hand
to 10 o'clock and repeat the previous step as
many times as necessary.
When this is done, set the watch to the correct
time. Take care not to go through midnight and
thus alter the date again.
