If you have not worn your watch for more than 7 days, the power
reserve display will go back to 0 and the watch will normally stop
at midnight, as the changeover of the calendar uses a great deal
of energy.
Warning:
If your watch has stopped between 10 p.m. and 2 a.m., you
should on no account alter the date using the rapid-advance
date display with the crown in position 1. This would result in
damage to a component in the calendar mechanism which would
require repair by a watchmaker. The same applies to turning the
crown too rapidly when setting the calendar.
We recommend winding the movement at least 20 times with
the crown in position 0. Then pull the crown out to position 2 in
order to set the hour and minute hands to approximately 6 a.m.
To set the time accurately to the second, it is best to stop the
movement as the small seconds hand passes 60. Push back the
crown to position 1. In this position, you can safely set the date
to the previous day. If you now pull the crown out to position 2,
you can set the exact time in hours and minutes. When doing this,
move the minute hand a few minute strokes beyond the time to be
set. Then position the minute hand by moving it gently backwards

until it is exactly above the correct minute stroke. This ensures that
the minute hand begins to move immediately when you restart
the movement. If the date does not jump to today's date when
it passes 12 o'clock, you must wind the hour hand forward by a
further 12 hours. Once the hour and minute have been set to the
correct time using this process, push back the crown to position 0.
Warning:
In order to protect the watch from the ingress of water, the crown
must always be in position 0 and should only be pulled out to
position 1 or 2 when setting the watch.

The power reserve display is divided into 7 days with continuous
display. The winding mechanism winds the watch continuously
while you are wearing it, and you can follow the process on the
power reserve indicator. The marking in the area of the last day
tells you that the power reserve is about to expire. You should
then wind the watch by hand, if necessary, since the precision
can be reduced in this area. In order to maximize the running
time of your watch, we recommend that you wind the crown up
to 8 additional revolutions beyond the marking of the full power
reserve (7 days).
