12-hour and 24-hour timekeeping
• With the 12-hour format, the P (PM) indicator appears to the left of the hour digits for
times in the range of noon to 11:59 p.m. and no indicator appears to the left of the
hour digits for times in the range of midnight to 11:59 a.m.
• With the 24-hour format, times are displayed in the range of 0:00 to 23:59, without
any indicator.
• The 12-hour/24-hour timekeeping format you select in the Timekeeping Mode is
applied in all other modes.
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.
E-63
• 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 (
AvtA) 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.
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.

current DST setting (Auto DST) will be retained. If you change to a city that is
outside your current transmitter area, DST will be turned off automatically.

Radio-controlled Atomic Timekeeping Precautions
• Strong electrostatic charge can result in the wrong time being set.
• The time calibration signal bounces off the ionosphere. Because of this, such factors
as changes in the reflectivity of the ionosphere, as well as movement of the
ionosphere to higher altitudes due to seasonal atmospheric changes or the time of
day may change the reception range of the signal and make reception temporarily
impossible.
• Even if the time calibration signal is received properly, certain conditions can cause
the time setting to be off by up to one second.
• The current time setting in accordance with the time calibration signal takes priority
over any time settings you make manually.
• The watch is designed to update the date and day of the week automatically for the
period January 1, 2000 to December 31, 2099. Setting of the date by the time
calibration signal cannot be performed starting from January 1, 2100.
• This watch can receive signals that differentiate between leap years and non-leap
years.
• Though this watch is designed to receive both time data (hour, minutes, seconds)
and date data (year, month, day), certain signal conditions can limit reception to time
data only.
