setting the calendar might result in a
faulty advance and the de syn chron
iza tion of the individual calendar dis
plays (e.g. date, day, moon phase).
In such a case, the movement needs
to be reset by an IWC watchmaker.
– You must not move the calendar
beyond the correct date. The com
plicated movement is mechanically
programmed and cannot be moved
back in time without making a pro
fessional adjustment to the move
ment. However, if you do move the
date forward beyond the correct
date, you have two options: you can
either pull out the crown to position
2 to stop the movement until the cal
endar setting matches the correct
date once again. This makes sense
