Please note:
– If the crown is turned too quickly, the display discs might not
be positioned correctly in the display window. Generally, such
a default is automatically corrected by the movement when the
calendar advances within the following 24 hours. Should this
not be the case, the movement needs to be reset by an IWC
watchmaker.
– 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 once again matches the
correct date. This makes sense if the date has been set only
a few days ahead. Or, you can slowly advance the calendar
by 4 years until you reach the correct date. Alternatively, you
can entrust this operation to your watchmaker.
