The Worldtimer has two separate time zone displays: T1 local time and T2 home time. Both have their own hour and minute hands. The minute hands of T1 and T2 run synchronously. The hour hand of T1 can be adjusted forwards or backwards, hour by hour, very quickly using the two pushers. The date changes forwards and backwards between 23:00 and 03:00 during this quick adjustment. T2 also has a day and night display.

Synchronize times, set time and date:
- If present, open the screw-down crown or QLC crown.
- Pull the crown to position 3, turn counterclockwise and set T2 to 05:00. The day/night display appears dark.
- Also set T1 to 05:00 using the +pusher, i.e. the date must have switched between 01:00 and 03:00.
- Push the crown into position 2, turn counterclockwise and set the date.
- Pull the crown back into position 3 and set the current time. Turn 12 hours further if it is afternoon. The watch is stopped in this position and can, for example, be started by pressing a time signal, i.e. in position 1.
- Push the crown into position 1.
- If present, close the screw-down crown or QLC crown.
It takes about 10 minutes for T1 and T2 to run synchronously again. The tolerance can be up to one minute.
Set T1 (local time):
- Press the + or - pusher once per hour time difference to T2 (home time).
- The date corrects itself forwards and backwards if the time adjustment is made with the + or - button after midnight.
