winding crown
The winding crown is used to wind the watch
(position 1) and to set the time (position 2).
winding
Your watch has a self­winding movement. The
movements of your wrist set a rotor in motion; this
tensions the mainspring which stores the energy.
Off the wrist, your watch has a power reserve of at
least 35 hours. When it has stopped after depleting
the power reserve, it can be rewound by hand (about
10 clockwise turns of the crown). Please wind the
watch before you put it on. This way, you can avoid
lateral pressure on the winding stem which in the
course of the years could damage the stem tube.
setting the time
To set the time, pull the crown out, and turn it in
either direction. When you turn the hands clock­
wise beyond midnight, the calendar displays will
advance as well. We advise against turning the
hands counterclockwise across midnight because
this would desynchronize the calendar displays;
however, it would not damage the calendar
mechanism.
Caution:
Please set the time before you put the watch on.
This prevents lateral pressure on the winding stem. Please
use your fingernails to pull the crown out and turn it gently
between two fingertips.
Never pull out the crown in a humid environment or underwa-
ter: the water resistance of your watch is assured only when
the crown is pushed home.
