World Time
World Time digitally displays the current time in one of 48 cities (29 time zones)
around the world. A simple operation swaps your Home City with the currently
selected World Time City.
The times kept in the World Time Mode are synchronized with the time being •
kept in the Timekeeping Mode. If you feel that there is an error in 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.
All of the operations in this section are performed in the World Time Mode, •
which you enter by pressing C.
Right Dial Hand
The right dial hand shows the current hour in the World Time City in all modes.
The right dial hand moves just like the normal hour hand, completing one •
revolution every 12 hours.
Between the noon and midnight in the World Time Mode, a PM indicator •
(PM
) appears above the right dial hand.
To view the current time in another time zone
In the World Time Mode, use D to scroll through available city codes (time zones).
Holding down the button scrolls at high speed.
When the city code (time zone) you want is selected, you can press • A to display the date. After about

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
In the World Time Mode, use 1. D to select the World Time City you want.
Hold down 2. 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.
