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.

 When you enter the World Time Mode, the current month 

 

•

and day of the World Time City appear first. After about 

one second, the current time appears.
 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” at the back of this manual for 

information about the UTC offsets that are supported.

 All of the operations in this section are performed in the World Time Mode, which

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”.

 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.
