IWC Schaffhausen Portugieser Grande Complication Mode D'emploi page 25

Pull out the crown to position 1. In this position, you can use the direct­advance func­
tion to move the calendar forwards one step at a time by turning the crown slowly to
the right. The calendar must not be adjusted between 8 p.m. and 2 a.m.
Please note:
– Turning the crown too quickly when setting the calendar might result in a faulty
advance and the desynchronization of the individual calendar displays (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 complicated move­
ment 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 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.
