− The initial default DST setting is “DST off (OFF)” when you have one of the
following cities specified as your Home City: HNL, HKG, BJS, TPE, SEL.
− The initial default DST setting is “DST off (OFF)” when you have a city that does
not support time signal reception specified as your Home City.

probably is best to switch between Standard Time and Daylight Saving Time
(summer time) manually.
EN-46
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) includes 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 time calibration signals transmitted from Fukushima and Fukuoka/Saga (Japan)
do not include summer time data.
x The initial default setting for DST depends on the city you have specified as your
Home City.
− The initial default DST setting is “Auto DST (AUTO)” when you have one of the
following cities specified as your Home City: ANC, YVR, LAX, YEA, DEN, MEX,
YWG, CHI, MIA, YTO, NYC, YHZ, YYT, LIS, LON, MAD, PAR, ROM, BER, STO,
ATH, MOW, TYO.

City code. For more information, see “Daylight Saving Time (DST)” below.
