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

 This will make the World Time City you selected in step 1 your new Home City, and cause the hour and 

 

x

minute hands to move to the current time in that city. At the same time, the Home City you had selected 
prior to step 2 will become your new World Time City. The content of the upper and lower displays will 
change accordingly.
 After swapping the Home City and World Time City, the watch stays in the World Time Mode with the 

 

x

city that was selected as the Home City prior to step 2 now displayed as the World Time City.

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 

 

x

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
