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 calen-
dar's automatic switching phase, i.e. beyond 2 a.m. If this situ-
ation 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.
