This section contains more detailed and technical information about watch operation.
It also contains important precautions and notes about the various features and
functions of this watch.

Power Saving
When turned on, Power Saving automatically enters a sleep state whenever the watch
is left for a certain period in an area where it is dark. The table below shows how
watch functions are affected by Power Saving.

• There are actually two sleep state levels: “display sleep” and “function sleep”.

60 to 70 minutes

(Display Sleep)

6 or 7 days

(Function Sleep)

Digital display off, but all functions are enabled and the
power saving on indicator flashes on the display
• Digital display off, but the power saving on indicator

flashes on the display

• All functions, including analog timekeeping, disabled

• Internal timekeeping maintained

• Wearing the watch inside your sleeve can cause it to enter the sleep state.

• The watch will not enter the sleep state while the digital time is between 6:00 AM

and 9:59 PM. If the watch is already in the sleep state when the digital time reaches
6:00 AM, however, it will remain in the sleep state.

• The analog hands move to the 12 o’clock position when the watch enters the

function sleep state. If the analog time and digital time do not match after the watch
recovers from the function sleep state, adjust the analog hand setting so it matches
the digital time.

• The watch will not enter the sleep state while it is in the Stopwatch Mode.
To recover from the sleep state
Perform any one of the following operations.

• Move the watch to a well-lit area. It can take up to two seconds for the display to turn

on.

• Press any button.

• Angle the watch towards your face for reading.
To turn Power Saving on and off

1. While any screen other than the last signal screen is on

the display in the Timekeeping Mode, hold down A
until the city code starts to flash, which indicates the
setting screen.

2. Press C nine times until the Power Saving on/off

screen appears.

3. Press D to toggle Power Saving on (

jsOo

) and off

(

jsOw

).

4. Press A to exit the setting screen.

• The Power Saving on indicator is on the display in all

modes while Power Saving is turned on.

Auto Return Features
• The watch automatically returns to the Timekeeping Mode if you do not perform any

button operation for two or three minutes while the Battery Level Screen is
displayed, or while in the Alarm, or Hand Setting Mode.

• If you leave a screen with flashing digits on the display for two or three minutes

without performing any operation, the watch automatically exits the setting screen.

Scrolling
The B and D buttons are used in various modes and setting screens to scroll
through data on the display. In most cases, holding down these buttons during a scroll
operation scrolls through the data at high speed.

Initial Screens
When you enter the Timekeeping, World Time, or Alarm Mode, the data you were
viewing when you last exited the mode appears first.

• 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.

• Normally, the signal reception date shown by the last signal screen is the date data

included in the received time calibration signal. When only time data is received,
however, the last signal screen shows the date as kept in the Timekeeping Mode at
the time of signal reception.

• If you are in an area where proper time calibration signal reception is impossible, the

watch keeps time within ±15 seconds a month at normal temperature.

• If you have problems with proper time calibration signal reception or if the time

setting is wrong after signal reception, check your current city code, DST (summer
time) settings, and transmitter mode setting. The following are the initial factory
defaults for these settings.

City code

DST (summer time)
Transmitter mode

BER

 (Berlin): Module 3364

LON

 (London): Module 3365

AvtA

 (Auto switching)

AvtA

 (Automatic selection)

• To find out the module number of your watch, look at its

back cover. The Module number (3364 or 3365) is
engraved inside the box on the back cover.

3364

The first signal search operation after
factory default settings are in effect, or after
the city code has been changed.
Any case other than the above.

1. Checks the Mainflingen signal first.
2. If the Mainflingen signal cannot be

received, checks the Rugby signal.

1. Checks the last successfully received

signal first.

2. If the last successfully received signal

cannot be received, checks the other
signal.

Transmitters
This watch is able to receive time calibration signals transmitted in Germany
(Mainflingen) and England (Rugby). You can select either one of the transmitters, or
you can configure the watch to select the transmitter that has the strongest signal
automatically.

• The following explains how the watch determines which transmitter it should check

first while the watch is configured for automatic transmitter selection.

• Auto receive is turned on whenever the transmitter mode is 

AvtA

, 

77

, or 

60

. Auto

receive is turned off when the transmitter mode setting is 

OFF

.

• Note that you can change the transmitter mode setting when 

LON

, 

PAR

, or 

BER

is selected as the Home City code.

• See “To select the transmitter mode” below.

The first signal search operation after
factory default settings are in effect, or
after the city code has been changed.
Any case other than the above.

1. Checks the Rugby signal first.
2. If the Rugby 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.

1. In the Timekeeping Mode, press D to display the last

signal screen.

2. Hold down A until the transmitter mode setting starts

to flash, which indicates the setting screen.

• If holding down A does not display the setting

screen, check the current Home City code setting.
Press D to return to the Timekeeping Mode screen
and then refer to “To set your Home City” for
information about city codes that support signal
reception.

3. Press D to select the transmitter mode setting you

want to use.

• The following are the available transmitter mode settings.

AvtA

: Automatic selection of the Mainflingen or Rugby signal

77

: Reception of the Mainflingen signal

60

: Reception of the Rugby signal

OFF

: Auto receive off

4. Press A to exit the setting screen and return to the last signal screen.

• If you want to the return to the Timekeeping Mode screen, press D.

• Signal reception can take up to 14 minutes when the 

AvtA

 option is selected.

Charging Guide
After a full charge, timekeeping remains enabled for up to about nine months.

• The following table shows the amount of time the watch needs to be exposed to light

each day in order to generate enough power for normal daily operations.

Outdoor Sunlight (50,000 lux)

Sunlight Through a Window (10,000 lux)

Daylight Through a Window on a Cloudy Day
(5,000 lux)

Indoor Fluorescent Lighting (500 lux)

8 minutes

30 minutes

48 minutes

8 hours

• Since these are the specs, we can include all the technical details.

• Watch is not exposed to light

• Internal timekeeping

• Display on 18 hours per day, sleep state 6 hours per day

• 1 light operation (1.5 seconds) per day

• 10 seconds of alarm operation per day

• 4 calibration receptions per day

• Stable operation is promoted by frequent charging.

• Signal reception is affected by weather, atmospheric conditions, and seasonal

changes.

• 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 automatically update the date and day of the week 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.

• Strong electrostatic charge can result in the wrong time being set.

• Even when the watch is within the reception range of the transmitter, signal

reception will be impossible if the signal is blocked by mountains or other geological
formations between the watch and signal source.
