zone where that city is located. When setting the time, it is important that you first
select the correct city code for your Home City (the city where you normally use the
watch). 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 city codes and Dual Time City are
displayed in accordance with the time and date settings you configure for the
Timekeeping Mode.

12-hour and 24-hour timekeeping
• With the 12-hour format, the PM indicator appears to the left of the hour digits for
times in the range of noon to 11:59 p.m. and no indicator appears to the left of the
hour digits for times in the range of midnight to 11:59 a.m.
• With the 24-hour format, times are displayed in the range of 0:00 to 23:59, without
any indicator.
• The 12-hour/24-hour timekeeping format you select in the Timekeeping Mode is
applied in all other modes.
Daylight Saving Time (DST)
Daylight Saving Time (summer time) advances the time setting by one hour from
Standard Time. Remember that not all countries or even local areas use Daylight
Saving Time.
The time calibration signals transmitted from Mainflingen (Germany), Anthorn
(England), or Fort Collins (the United States) include both Standard Time and DST
data. When the Auto DST setting is turned on, the watch switches between Standard
Time and DST (summer time) automatically in accordance with the signals.
• Though the time calibration signals transmitted by the Fukushima and Fukuoka/
Saga, Japan transmitters include summer time data, summer time currently is not
implemented in Japan (as of 2009).
• The default DST setting is Auto DST (
PAR, ROM, BER, STO, ATH, MOW, TYO, ANC, YVR, LAX, YEA, DEN, MEX, CHI,
MIA , YTO , NYC , YHZ , or YYT as your Home City code.
• If you experience problems receiving the time calibration signal in your area, it
probably is best to switch between Standard Time and Daylight Saving Time
(summer time) manually.
To change the Daylight Saving Time (summer time) setting
1. In the Timekeeping Mode, hold down A for about five
seconds until the left dial hand points to T1 and the city
code flashes on the upper display. This is the setting
screen.

Dual Time
Dual Time lets you display the current time in another time zone called your "Dual
Time City", in addition your Home City's current time. This feature is very handy for
business professionals and others who need to keep track of the current time in two
different time zones.
• For information about how to display the current time in the Dual Time City in the
lower display, see "Timekeeping".
To specify the Dual Time City
1. In the Timekeeping Mode, hold down A for about five
seconds until the left dial hand points to T1 and the city
code flashes on the upper display.
