Transmitters
This watch is designed to receive the time calibration signal transmitted from Anthorn,
England and the signal from Mainflingen, Germany.
• The following explains how the watch determines which transmitter it should check
first.
Module 4321
In this case:
The first signal auto search operation
after factory default settings are in effect,
or after the city code has been changed
Any case other than the above.
The watch does this:
1. Checks the Mainflingen signal first.
2. If the Mainflingen signal cannot be
received, checks the Anthorn signal.
1. Checks the last successfully received
signal first.
2. If the last successfully received signal
cannot be received, checks the other
signal.
Module 4322
In this case:
The first signal auto search operation
after factory default settings are in effect,
or after the city code has been changed
Any case other than the above.
The watch does this:
1. Checks the Anthorn signal first.
2. If the Anthorn signal cannot be received,
checks the Mainflingen signal.
1. Checks the last successfully received
signal first.
2. If the last successfully received signal
cannot be received, checks the other
signal.
• To find out the module number of your watch, look at its
back cover. The Module number (4321 or 4322) is
engraved inside the box on the back cover.
Timekeeping
• Resetting the seconds to 00 while the current count is in the range of 30 to 59
causes the minutes to be increased by 1. In the range of 00 to 29, the seconds are
reset to 00 without changing the minutes.
• The day of the week is automatically displayed in accordance with the date (year,
month, and day) settings.
• The year can be set in the range of 2000 to 2099.
• The watch’s built-in full automatic calendar makes allowances for different month
lengths and leap years. Once you set the date, there should be no reason to change
it except after you have the watch’s battery replaced.
• The current time for all city codes in the Timekeeping Mode and World Time Mode is
calculated in accordance with the Greenwich Mean Time (GMT) differential for each
city, based on your Home City time setting.
• GMT differential is calculated by this watch based on Universal Time Coordinated
(UTC*) data.
* UTC is the world-wide scientific standard of timekeeping. It is based upon carefully
maintained atomic (cesium) clocks that keep time accurately to within microseconds. Leap
seconds are added or subtracted as necessary to keep UTC in sync with the Earth’s rotation.
The reference point for UTC is Greenwich, England.
12-hour/24-hour Timekeeping Formats
The 12-hour/24-hour timekeeping format you select in the Timekeeping Mode is also
applied in all other modes.
• With the 12-hour format, the P (PM) indicator appears on the display for times in the
range of noon to 11:59 p.m. and no indicator appears 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.
Illumination Precautions
An LED (light-emitting diode) and a light guide panel illuminate the face of the watch
for easy reading in the dark. In any mode, press B to illuminate the face of the watch
for about one second.
• The illumination provided by the light may be hard to see when viewed under direct
sunlight.
• Illumination automatically turns off whenever an alarm sounds.
• Frequent use of illumination shortens the battery operating time.

• If you have problems with proper time calibration signal reception or if the time
setting is wrong after signal reception, check your Home City code, DST (summer
time), and auto receive settings. The following are the initial factory defaults for these
settings.
