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 signal transmitted from Mainflingen includes both Standard Time
and DST data. When the DST setting is turned on, the watch switches between
Standard Time and DST (summer time) automatically in accordance with the
Mainflingen signal.

The default DST setting is Auto DST (

A

) whenever you select 

BER

PAR

LON

,

or 

ATH

 as your Home City code.

If you experience problems receiving the time calibration signal in your area, it is
probably 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.

4. When the setting you want is selected, press 

A

 twice to exit the setting screen.

Analog Timekeeping
The analog time of this watch is synchronized with the digital time. The analog time
setting is adjusted automatically whenever you change the digital time.

Note

The hands for the analog timepiece move to adjust to a new setting whenever any of
the following occurs.

When you change the digital time setting manually
When the digital time setting is changed by time calibration signal reception
When you change the Home City code and/or DST setting

If the analog time does not match the digital time for any reason, use the procedure
described under “To adjust the analog time” to match the analog setting to the digital
setting.

Whenever you need to adjust both the digital and the analog time settings manually,
make sure you adjust the digital setting first.

Depending on how much the hands have to move in order to adjust to the digital
time, it may take some time before the analog hands stop moving.

World Time

The World Time Mode digitally displays the current time in
30 cities (29 time zones) around the world.

about two seconds.

If the current time shown for a city is wrong, check your
Home City time settings and make the necessary
changes.

The watch will perform a signal receive operation even if
it is in the World Time Mode when a calibration time is
reached. If this happens, the World Time Mode time
settings will be adjusted in accordance with the
Timekeeping Mode’s Home City time.

All of the operations in this section are performed in the
World Time Mode, which you enter by pressing

The DST indicator will appear on the display whenever
you display a city code for which Daylight Saving Time is
turned on.

Note that the DST/Standard Time setting affects only the
currently displayed city code. Other city codes are not
affected.

Alarms

The Alarm Mode gives you a choice of four one-time
alarms and one snooze alarm. One of the one-time
alarms functions as a “target alarm,” which counts the time
