When setting the digital time, you can also configure settings for summer time
(Daylight Saving time or DST), your Home City code (the code for the city where you
normally use the watch), and the 12/24-hour format.
• This watch is preset with a number of city codes, each of which represents the time
zone where that city is located. When setting the digital time, it is important that you
select the correct city code for your Home City. If your location is not included in the
preset city codes, select the preset city code that is in the same time zone as your
location.
• Note that all of the times for the World Time Mode city codes are displayed in
accordance with the digital time and date settings you configure in the Timekeeping
Mode.

timekeeping with a different city code simply by changing the Home City code in the
Timekeeping Mode.

code. Other city codes are not affected.
