The 24-hour hand shows the second time zone of your choice on
the 24-hour scale, which runs around the edge of the dial.

The International Date Line largely coincides with the 180th
degree of longitude on the surface of the earth. Yesterday's date
applies if this line is crossed in an easterly direction, and you
move into the next day if it is crossed in a westerly direction. The
same date applies throughout the entire world only once a day,
namely at midnight on the International Date Line.

When crossing into another time zone, you can set the time dis-
play to the appropriate local time. The date display is automat-
ically readjusted by adjusting the hour hand to the actual time
zone. The 24-hour hand is unaffected by this operation.
