winding crown
The winding crown is used to wind the watch
(position 1) and to set the time (position 2).
winding
Your watch incorporates a self-winding movement.
The movements of your wrist set a centrifugal mass
in motion: this tensions the mainspring which
stores the energy. When you take off your fully
wound watch, it will continue to run for at least
50 hours. When it has stopped after depleting the
power reserve, it can be rewound by hand with
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
Gently pull the crown out and move the hands
clockwise or counterclockwise until they indicate
the current time.
