Read This Before You Set the Time and Date!

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.

(year, month, and day) settings.

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 2007).

• The default DST setting is Auto DST (

AvtA

) whenever you select

• 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.
