Please note:
You must not move the calendar beyond the correct date. The complicated
movement is mechanically programmed and cannot be moved back in time
without making a professional adjustment to the movement. However, if you
do move the date forwards beyond the correct date, you have two options:
You can either pull out the crown to position 2 to stop the movement until the
calendar setting matches the correct date once again. This makes sense if the
date has been set only a few days ahead. Or, you must take your watch to your
watchmaker, who will be able to adjust the movement to reset the calendar.
This is recommended in the event of larger maladjustments.
Time setting
Pull out the crown to position 2. This will stop the movement and the small
seconds hand at 9. To set the time accurately to the second, it is best to stop
the movement as the seconds hand passes 60. Now 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 immedi-
ately when you restart the movement. To start the seconds hand, push in the
crown to position 0. Moving the hands forwards past midnight causes the
calendar to switch to the following day. When advancing the calendar, you
can follow and observe the automatic switching sequence. Please pay
attention to the following to avoid maladjustment and possible damage to
the mechanism:
Under no circumstances must the hands be turned back between 8 p.m.
•
and 2 a.m.
The hands must never be turned anticlockwise beyond 2 a.m.
