IWC Schaffhausen PORTUGIESER PERPETUAL CALENDAR Mode D'emploi page 30

the correct minute stroke. This ensures that the minute hand
begins to move immediately when you restart the movement.
– Push the crown back to position 0 to start the movement.
The entire calendar is now automatically set correctly. There is no
need for you to know the current phase of the moon or whether
you are in a leap year. You do not even need to set the day of the
week. This simplified setting is very convenient, particularly if you
have not worn your IWC watch for a few days.
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 maximise 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).
