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 Fort Collins 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 Fort
Collins signal.
• The time calibration signals transmitted from Fukushima and Fukuoka/Saga do not
include summer time data.
• The default DST setting is Auto DST (
A
) whenever you select

time) manually.

• 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.
