your Home City code (the code for the city where you normally use the watch),
summer time (Daylight Saving time or DST), the 12/24-hour format, and power
saving on/off.

• Auto DST (AUtO) can be selected only while LON , PAR , BER , or ATH is selected
as the Home City code. For more information, see “Daylight Saving Time (DST)” below.
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 Rugby and Mainflingen 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 received time signal.
• The default DST setting is Auto DST (AUtO) whenever you select LON , PAR ,
BER , 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.
