IWC Schaffhausen DA VINCI PERPETUAL Mode D'emploi page 34

Setting when crossing the International Date Line:
– When crossing the International Date Line in a westerly direc-
tion (you enter the next day, regardless of the time of day),
simply turn the time forward to the new local time, and the date
change will take place automatically.
– When crossing the International Date Line in an easterly dir-
ection (you enter the previous day, regardless of the time of
day), you must likewise set your watch forward to the new local
time. However, your watch will now indicate the wrong date
(one day too many). This incorrect date indication can be cor-
rected by resetting the hands twice, by 12 hours on each oc-
casion:
– Setting the watch back by 12 hours during the afternoon
between 2 p.m. and 8 p.m. will prevent the calendar from
advancing at midnight.
– Setting the watch back another 12 hours the following morn-
ing between 2 a.m. and 11 a.m. will synchronize the date
display with the local date.
