Setting when crossing time zones:
– When crossing time zones in an easterly direction, you should simply set the time
forwards to the new local time.
– When crossing time zones in a westerly direction, you can set the hands of your
watch back to the actual time of day. When doing this, however, you must not
move back into the calendar’s automatic switching phase, i.e. beyond 2 a.m. If this
situation occurs when you are travelling west, you should set the local time of your
destination before 8 p.m. You must not turn the hands back between 8 p.m. and
2 a.m.
Setting when crossing the International Date Line:
– When crossing the International Date Line in a westerly direction (you enter the next
day, regardless of the time of day), simply turn the time forwards to the new local
time, and the date change will take place automatically.
– When crossing the International Date Line in an easterly direction (you enter the
previous day, regardless of the time of day), you must likewise set your watch for­
wards to the new local time. However, your watch will now indicate the wrong date
(one day too many). This incorrect date indication can be corrected by resetting the
hands twice, by 12 hours on each occasion:
– 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 morning between 2 a.m.
and 11 a.m. will synchronize the date display with the local date.
