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 signals transmitted by the Fukushima and Fukuoka/
Saga, Japan transmitters include summer time data, summer time currently is not
implemented in Japan (as of 2010).
• The default DST setting is Auto DST (
) whenever you select LIS, LON, MAD,
PAR, ROM, BER, STO, ATH, MOW, TYO, ANC, YVR, LAX, YEA, DEN, MEX, CHI,
NYC, YHZ, or YYT as your Home City code.
• 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.

Moon Phase Indicator
The Moon phase indicator of this watch indicates the
current phase of the Moon as shown below. It is based on
the view of the left side of the moon at meridian transit
from the northern hemisphere of the Earth. If the
appearance of the Moon phase indicator is reversed from
the actual Moon as viewed from your location, you can
use the procedure under “To reverse the displayed Moon
phase” (page E-40) to change the indicator.
