Automatic mechanical watches
Your watch must be wound manually if it has stopped or not been worn for
several days, in order to ensure that your watch remains in continuous opera-
tion during periods of low activity (e.g. during sleep).
In these cases, turn the crown through 30 revolutions forward in position I.
The automatic winding system will then ensure that the movement is fully
wound if the watch is on your wrist. It is also possible to fully wind an auto-
matic watch manually by means of the winding crown. However, please note
that automatic movements have a slipping spring, which disengages the
winding system (the crown can be turned infinitely) once the movement has
been fully wound. Generally speaking, 80 revolutions of the crown are
enough to fully wind most automatic mechanical watches.
The efficiency of the automatic winding system of a mechanical movement
depends on the wrist movements of the person wearing the watch. Do not
deliberately shake your automatic watch to wind it; this has no effect and
could damage the watch.
Setting the time
Pull the crown out to position III and turn it in either direction until the desired time
is displayed.
Rapid correction of the date
NB: Do not perform a rapid date correction between 22:00 and 02:00.
Pull the crown out to position II and turn it clockwise until the desired date is
displayed. During this operation, your watch will keep operating, so you will not
need to adjust the time.
