WINDING CROWN
The winding crown is used to wind the watch (po-
sition 1) and to set the time (position 2).
MANUALLY WOUND
Your watch has a manually wound movement.
When fully wound, it has a power reserve of at
leat 38 hours. We recommend that you wind
your watch each day at about the same time, pref-
erably in the morning (about 15 clockwise turns
of the crown).
Caution: 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. Turn the crown gently and uniformly and stop as soon
as you feel resistance; if you wind the watch too vigorously,
this might damage the movement.

SETTING THE TIME
To set the time, pull the crown out, and turn it in
either direction. The day/night indicator makes it
possible to distinguish between am and pm hours
(white = morning hours between 0:00 midnight
and 11:59 am, black = afternoon hours between
12:00 noon and 11:59 pm). When you turn the hands
clockwise beyond midnight, the calendar displays
will advance as well. We advise against turning
the hands counterclockwise across midnight be-
cause this would desynchronize the calender dis-
plays; however, it would not damage the calendar
mechanism. Set the hands to the correct time, then
push the crown home again. The movement has a
stop-seconds mechanism that allows the watch to
be synchronized with a time signal to an accuracy
of one second. The seconds hand stops when the
winding crown is pulled. It starts running again as
soon as you push the crown home again.
