any World Time Mode time, check to make sure you
have the correct city selected as your Home City. Also
check to make sure that the current time as shown in
the Timekeeping Mode is correct.
• Times in the World Time Mode are based on UTC
offsets. See the “City Code Table” for information about
the UTC offsets that are supported.

Swapping your Home City and World Time City
You can use the procedure below to swap your Home City and World Time City. This
changes your Home City to your World Time City, and your World Time City to your
Home City. This capability can come in handy when you frequently travel between two
cities in different time zones.
• If your current World Time City supports receipt of a time calibration signal, making it
your Home City enables calibration signal reception.
• For information about which cities support time calibration signal reception, see “To
specify your Home City”.
To swap your Home City and World Time City
1. In the World Time Mode, use D to select the World Time City you want.
2. Hold down A and B until the watch beeps.
• This will make the World Time City you selected in step 1 your Home City, and cause
the hour and minute hands to move to the current time in that city. At the same time,
it will change the Home City you had selected prior to step 2 your World Time City,
and cause the content of the upper and lower displays to change accordingly.
• After swapping the Home City and World Time City, the watch stays in the World
Time Mode with the city that was selected as the Home City prior to step 2 now
displayed as the World Time City.
