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 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 Mode city
codes are displayed in accordance with the time and
date settings you configure in the Timekeeping Mode.

12-hour and 24-hour timekeeping
With the 12-hour format, the P (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 signal transmitted by the Fukushima and Fukuoka/Saga,
Japan transmitters include summer time data, summer time currently is not
implemented in Japan (as of 2008).
The default DST setting is Auto DST (
AvtA) whenever you select LIS, LON, MAD,
PAR, ROM, BER, STO, ATH, MOW, TYO, ANC, YVR, LAX, YEA, DEN, MEX, CHI,
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 until the city
code starts to flash, which indicates the setting screen.
2.Press C and the DST setting screen appears.
3.Use D to cycle through the DST settings in the
sequence shown below.

If you change your Home City to one that is within the same transmitter area, the
current DST setting will be retained. If you change to a city that is outside your
current transmitter area, DST will be turned off automatically.
