This solar radio-controlled watch is equipped with a time zone adjustment function.
The watch can automatically display local time in a different time zone by selecting the time zone.
It can receive official standard frequencies of Germany, the United States and Japan to adjust the
time.
AUTOMATIC TIME SETTING
■
The watch m aintains the precis e time by automatically r eceivin g radio signals on an offic ial
standard frequency. The watch can receive official standard frequencies of Germany, the United
States, and Japan (from either of two transmitting stations) by selecting the time zone.
Manual reception is also possible (the watch is unable to receive radio signals outside of the
reception range of each standard frequency).
DISPLAY OF RADIO SIGNAL RECEPTION LEVEL
■
During reception attempts, the watch displays the reception level of radio signals.
DISPLAY OF RADIO SIGNAL RECEPTION RESULT
■
Reception result (succeeded or failed) can be confirmed following reception of radio signals.
AUTOMATIC CALENDAR
■
The calendar adjusts odd and even months including February in leap years.
TIME ZONE ADJUSTMENT
■
The watch can be set to local time in a different time zone by selecting a time zone.
AUTOMATIC HAND ALIGNMENT
■
When the hand positions display incorrect time as a result of the influence of various external
sources, the watch automatically corrects the hand alignment itself.
SOLAR RECHARGEABLE BATTERY
■
A solar cell underneath the dial converts any form of light into "electrical energy” to power the
watch and the power is stored in a secondary battery. Once fully charged, the watch continues
to run for approximately six months.
ENERGY DEPLETION FOREWARNING FUNCTION
■
The movement of the second hand indicates that the battery should be charged.

CHARGING THE SOLAR BATTERY
HOW TO CHARGE THE WATCH
This watch is a solar-powere d watch containi ng a solar cell underneath the dial to convert any
form of light into "electrical energy” and store the power in a secondary battery.
To enj oy opti mal per fo rma nce
of this watch, it is recommended
that the watch be kept sufficiently
charged at all times.
*Be fore init ia lly using the watch
or wh en the wa tc h has stop ped
as a r esult of com plete depletion
of stored power, charge the watch
sufficiently.
STANDARD CHARGING TIME
*The table above is only provided as an approximation.
The figures in the table above refer to the time required to charge the stopped watch by exposure to light until the
★
watch moves at steady one-second intervals, through two-second intervals and five-second intervals.
Even if the watch is partially charged for a period shorter than the time provided in the above table, it will resume
one-second interval movement; however the one-second interv al movement will change to two-second interval
movement shortly. To avoid this and charge the watch to a sufficient level, use the charging time mentioned above
as a measure.
*The required charging time slightly varies depending on the model of the watch.

CHECKING THE CHARGING STATUS BY THE MOVEMENT OF
THE SECOND HAND
*1. If the second hand is stopped even after the watch is sufficiently charged, refer to "TROUBLESHOOTING" on pages 64-65.
*2. After the watch receives a radio signal, when the date is incorrect even if the correct time is displayed,
check that the calendar is set to the preliminary position (refer to “PRELIMINARY POSITION CHECKING
AND SETTING FOR THE CALENDAR” on pages 58-59).
ENERGY DEPLETION FOREWARNING FUNCTION
The energy depletion forewarning function is activated when the energy stored in the watch runs
low. In such a cas e, the second hand moves at two-second intervals. If the wa tch continues
to be in the state of two-second interval movement, the watch switches to five-second interval
movement, followed by a completely stopped state.
If the energy depletion forewarning function is activated, charge the watch sufficiently.
HOW TO CHARGE THE WATCH…page 10
STANDARD CHARGING TIME…page 11
* Neither the buttons nor the crown can be operated while the second hand moves at two-second or five-
second intervals (this is not a malfunction).
* While the second hand moves at five-second intervals, the hour and minute hands and calendar stop
operating.
* While the second hand moves at five-second intervals, the watch is u nabl e to receive radio signals
automatically. After the watch is charged sufficiently and the second hand returns to normal one-second
interval movement, conduct the manual reception of radio signals to set the watch to the correct time. After
completing the radio signal reception, when the date is incorrect even if the correct time is displayed, check
that the calendar is set to the preliminary position (refer to “RADIO SIGNAL RECEPTION” on page 20 and
“PRELIMINARY POSITION CHECKING AND SETTING FOR THE CALENDAR” on pages 58-59).

POWER SAVE FUNCTION
Whe n the wat ch is no t expo se d to an adequ at e ligh t sour ce , the powe r save func tio n is
automatically activated in order to reduce unnecessary energy consumption.
When this state continues for 72 hours or longer, the watch enters "the Power Save One” mode.
If the watch continues to be insufficiently charged, and the stored power falls below a certain level,
the watch automatically switches to "the Power Save Two” mode.
[POWER SAVE 1]
•When this state continues for 72 hours or longer, the watch enters
"the Power Save One” mode.
•When the w atch is in "the Power S ave One” mode, the second
hand rotates to point to the 15-second position and stops.
•In this state, mov em en t of the hou r and min ut e hand s and
cal end ar opera tio n will cea se , but the watch wi ll cont inu e to
conduct automatic reception.
•To rese t the watc h to disp la y the curr en t time , expo se it to
adequate light for five seconds or longer.
* When the watch returns to its normal movement, the watch hands rotate rapidly to display the current time. After
the watch hands are set to the current time, the correct date is displayed.
[POWER SAVE 2]
•If the watch continues to be insufficiently charged, an d the stored power fall s below a certain
level, the watch automatically switches to "the Pow er Save Two” mode, to limit further e nergy
consumption. When the watch is in "the Power Save Two” mode, the second hand rotates to point
to the 45-second position and stops.
•In this state, movement of the hour and minute hands and calendar operation will cease and the
watch will also stop conducting automatic reception.
•When the watch enters "the Power Save Two” mode, immediately
charge the watch.
* While the watch is b eing charged, the second hand moves at five-s econd
intervals. During the five-second interval movement, neither the buttons nor the
crown can be operated (this is not a malfunction).
* If “the Power Save Two” mode is prolonged, the amount of stored power drops
and the in ternal t ime sett ings wil l be lost. In s uch a case, after c ompleting
battery charging, conduct the manual reception to set the watch to the correct
time. After co mpleting th e radio signal r eception, when the date is incorrect
even if the c orrect time is d isplayed, chec k tha t the calen dar is set to the
preliminary position (refer to “RADIO SIGNAL RECEPTION” on page 20 and “ PRELIMINARY POSITION CHECKING
AND SETTING FOR THE CALENDAR” on pages 58-59).

WARNING
WARNING
The solar cell underneath the dial c onverts light into "e lectric al energy ” and stores the po wer
in a secondary battery. When the secondary battery is fully charged, the overcharge prevention
function is automa tically activated to avoid further charging. There is no need to wor ry about
damage caused by overcharging no matter how much the secondary battery is charged in excess
of the "time required for fully charging the watch.”
*Refer to “
STANDARD CHARGING TIME
(Notes on charging the watch)
When charging the watch, do not place t he watch in close proximity to an intense light
source such as lighting equipment for photography, spotlights or incandescent lights, as
the watch may be excessively heated resulting in damage to its internal parts.
When charging the watch by exposure to direct sunlight, avoid places that easily reach
high temperatures, such as a car dashboard.
Always keep the watch temperature under 60ºC.
” on page 11 to check the time required for fully charging the watch.
POWER SOURCEOVERCHARGE PREVENTION FUNCTION
•The battery used in this watc h is a special secondary battery, which is different from ordinary

WHAT IS A RADIO-CONTROLLED WATCH?
The radio-contro lled watch display s the precise time and d ate by auto matically rece iving and
synchronizing itself with the radio signal of an official standard frequency.
Time signal transmitted by a standard frequency is based on a super accurate "Ce sium Atomic
Clock” that may have a 1 second loss or gain per one hundred thousand years
AUTOMATIC HAND ALIGNMENT
Under normal operation, periodic checks of each hand position are performed once every one-
minute for the second hand position, and once every twelve hours for the hour and minute hand
positions.
<When the hand positions move out of alignment >
Strong shocks can cause misalignment of the hand positions
・
The hand positions may move out of alignment due to strong shocks to the watch when the watch is dropped or
hits against a hard surface.
Strong magnetism can cause misalignment of the hand positions.
・
The hand positions may move out of alignment due to strong magnetism generated by mobile phones, speakers,
magnetic therapy devices, or other magnetized objects.
When the watch is stopped due to complete depletion of stored power
・
The radio-controlled watch automatically sets itself to the precise time. However, if the preliminary
hand positions are misaligned when the time is set, the watch will be unable to display the precise
time even after it receives a radio signal properly. It is like a scale which cannot display the correct
weight because its hand is not set to the 0 position before weighing.
Be assured that all hand positions of this watch are automatically corrected as long as the watch
receives radio signals properly, omitting complicated procedures.

because of interference. The w atch may fail to receive radio signals depending on the
location or reception conditions. In such a case, change the location of the watch.
- Radio signals can easily be received during nighttime hours due to its characteristics.
- The watch moves depending on the quartz movement (loss/gain: ±15 seconds per month)
when it is unable to receive radio signals.
- The time signal transmission may be stopped during maintenance of the facilities of each
transmitting station or because of a lightning strike. In such a case, see each station’s
website for further information.

WHAT IS A TIME ZONE?
TIME ZONE AND TIME DIFFERENCE
Time zone means the region where the common standard time is used. There are 24 time zones
around the world based on time differences from UTC (Uni versal Coordinated Time). In some
regions daylight saving time (DST) is adopted.
[What is UTC (Universal Coordinated Time)?]
UTC is the universal standard time coordinated through international agreement. It is used as the
official time around the world. UTC is determined by adding a leap second to GMT (Greenwich
Mean Time), which is determined through astronomical measurement, in order to keep the precise
time.
[What is summer time (DST)?]
Summer time is daylight saving time. Advancing the watch one hour to prolong daytime during
longer daylight hours in summer. Daylight saving time has been adopted in about 80 countries,
mainly in Europe and North America. The adoption and duration of daylight saving time vary
depending on the country.

While summer time is in effect, select the time zone 1 hour
ahead.
Fol low the direc tio n of th e arrow ma rk (clo ck wis e) to
advance the second hand for the length of one arrow mark.
* Refer to “TIME ZONE DISPLAY” on pages 36-39.
* Refer to “HOW TO SELECT THE TI ME ZONE” on pages
40-41.
In an env ir on me nt wher e Ger man sta nd ar d ra di o
signals (DCF77) can be continuously received, SUMMER
TIME automatic change can be made (refer to “ SUMMER
TIME automatic change” ).
* T he time differen ces and use o f daylig ht savin g time in eac h
area are subject to change according to the governments of the
respective countries or regions.
SUMMER TIME AUTOMATIC CHANGE FUNCTION
As long as your watch is used in an environment where German standard radio signals (DCF77)
can be continuously received, the time zone can automatically be c hang ed by r ecei ving the
stand ard radio signals indicati ng "entering summer tim e” or "re turni ng to no rmal time from
summer time” to display the changed time.
*Refer to “●In the case where the summer time change function cannot be automatically reset" on page 44.
In the case where a summer time change automatically functions
<Ex. 1>
In Germany, your watch is used in an environment where the reception state is good. (Automatic reception, etc., can
be made.)
After automatically changing to summer time, reception was successful.
Your watch displays summer time for which 1 hour is added to normal time. Checking the time zone,
you find that it displays “CAIRO.”
Page 23

<Ex. 2>
During summer time in Germa ny, you used yo ur watch with the tim e zone adjusted for “ CAIRO.” As reception
failed and the time remained ind icating summer time when s ummer time h ad ended, whe n manual rece ption was
attempted, reception was successful.
The time indicates the correct time after summer time. Checking the time zone, you find that it
displays “PARIS/BERLIN.”
In the case where a summer time change cannot be automatically reset
<Ex.>
You move to Germa ny during summer tim e from an area that differs in tim e zone. After changing tim e zone and
selecting “PARIS/BELRIN,” reception was succe ssful by manual rec eption; howe ver, your watch did not display
summer time.
In the case of summer time, select “CAIRO” not “PARIS/BELRIN.”
QUESTIONS AND ANSWERS ABOUT THE TIME ZONE ADJUSTMENT FUNCTION
Q: When the watch is moved to a different time zone, is the time automatically changed to the time
of the area?
A: The watch will n ot be automatica lly set to the local time if it is j ust moved to a plac e in a
different time zone. Select the time zone where you are when you travel.
If you select the time zone, the watch is automatically set to the local time.
(Adjust the time zone by one hour units according to the original time.)
If the time zone is within the reception range of radio signals, you can leave the watch to receive
the radio signal to set it to the precise time.
(The receivable standard frequency can be changed by selecting a time zone.)
Q: Summer time information should be contained in a standard frequency. Isn’t it necessary to
set summer time manually if the time zone within the radio signal reception range is properly
selected?
A: Some areas or countries in a time zone may not have adopted summer time. Therefore, the
watch is designed so that summer time can be manually selected. However, a summer time
automatic change can be made as long as your watch is used in an environment where German
standard radio signals (DCF77) can be continuously received.
