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 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, proceed as follows:
1. Press the pusher at 10 o'clock as often as needed
to advance the city name that represents your
time zone to the 12 o'clock position.
2. Pull the crown out and move the hands clock-
wise or counterclockwise until they indicate the
time in your time zone. Make sure the 24-hour
ring indicates the correct time of day directly
opposite the city name at 12 o'clock. The illustra-
tion shows local time in London at 10.10 a.m.
