§3. SOLAR POWER WATCH
This watch is powered not by an ordinary battery, but by converting light energy into electrical
energy.
A secondary battery is used in this watch to store electrical energy. This secondary battery is a
clean energy battery which doesn’t use any toxic substances such as mercury. Once fully
charged, the watch will continue to run for about 6 months without further charging.
[Explain the following items to the user for comfortable use of this watch.]
<Good use of solar-powered watch>
•Since the energy source of this watch is light, expose it to light sufficiently to charge the battery
in it.
•The battery of this watch is never overcharged by exposing it to light.
•If the user wears long-sleeved clothes usually, the watch is covered and its battery may not be
charged sufficiently.
•The watch should be put on a well lit plance as long as possible for its normal operation while
it is not worn.
[Replacing the secondary battery]
Unlike ordinary silver-based batteries, the secondary battery used in this watch does not have to
be periodically replaced since it is able to be charged and discharged repeatedly.
§4. HANDLING OF WATCH

<Helpful hint for setting the time accurately>
After first stopping the second hand at the 0 seconds position, advance the minute hand 4-5 min-
utes past the correct time and then turn it back to the correct time. Then push in the crown in
synchronization with a telephone or other time service to accurately set the time.
■Setting the calendar
1. Pull the crown out to the 1st click (calendar setting position).
2. Set the desired date by turning the crown counterclockwise.
3. Set the desired day of the week by turning the crown clockwise.
•In the case of date display models, turning the crown clockwise will result in the loose play
of the crown.
4. After you have set the calendar, be sure to press the crown back to its normal position.
•Do not adjust the calendar when the watch is reading as below. Otherwise the calendar
may not change correctly.

B. Functions of the Solar Power Watch
If the charge becomes insufficient, a warning function will operate and the display changes, as
below.
■Insufficient Charge Warning Function This feature indicates that the watch has
become insufficiently charged when the sec-
ond hand changes from 1-second interval
movement to 2-second interval movement.
Even in such a case, the watch keeps correct
time, but about 4 days after two-second interval
movement begins, the watch will stop.
After exposing the watch to light, recharging
takes place and the watch returns to one-second
interval movement.
■Quick Start Function
The watch will stop if it is completely discharged.
It will begin to operate soon after (within 10 second) it is exposed to light.
(However, the time to start may vary according to the brightness of the light.)
■Overcharging Prevention Function
When the secondary battery becomes fully charged as result of light shining into the watch dial
(solar cell), the over charge prevention feature is activated automatically to prevent the sec-
ondary battery from being charged further. This prevents the secondary battery as well as time-
keeping accuracy, functions and performance of the watch from deteriorating no matter how
much the watch is charged.

D. Notes on Recharge
•Avoid charging the watch at high temperatures (about 60°C / 140°F or higher) since allowing
the watch to reach a high temperature during charging can cause deformation or discoloration
of external components as well as a malfunction of movement components.
Examples:
•Charging by placing the watch too close to a light source that may become hot such as an
incandescent lamp or halogen lamp.
•Charging by placing the watch on an automobile dashboard that can easily reach a high
temperature.
•When charging the watch with an incandescent lamp, halogen lamp or other light source that
may reach a high temperature, always make sure to place the watch at least 50 cm (20 in.)
away from the light source to prevent the watch from reaching a high temperature.
E. Replacing the Secondary Battery
This watch uses the secondary battery, which does not have to be periodically replaced
due to repeated charging and discharging, unlike ordinary batteries.
Caution
Never use a battery other than the secondary battery used in this watch.
The watch structure is so designed that a different kind of battery other than the specified cannot
be used to operate it. In case a different kind of battery such as a silver battery is used by some
chance, there is a danger that the watch will be overcharged to burst, causing damage to the
watch and even to the human body.
§5. PRECAUTIONS FOR DISASSEMBLY AND ASSEMBLY
A. How to Pull Out Setting Stem from One-piece Case

2. When removing the setting stem from the movement
•Pressing the base of the unlocking lever for setting stem (“PUSH →”position), pull out the set-
ting stem.
<Note>
When the movement has been removed from the case, do not press the end of the unlocking
lever for setting stem. If it is pressed in this case, it may be pressed too much to deform
itself, circuit unit supporter, etc. since there is not a stopper.
If the movement is installed to the case with any part deformed, the setting stem may not be
pulled out even if the unlocking lever for setting stem is pressed.
<Procedure>
(1) Set the crown at the normal position (Push it
in).
(2) Lightly press the base of the unlocking lever
for setting stem (“PUSH →”position) with a
screwdriver, etc. from above.
(3) With the lever pressed, pull out the setting
stem.
B. Procedure for Assembling Solar Cell
1. Precautions for handling of solar cell
•If the top of the solar cell is damaged, its charging capacity and other functions are lowered.
Accordingly, sufficiently take care not to damage the top of the solar cell when removing and
setting it.
•If the electrodes are stained or flaked off, a continuity trouble occurs. Since it is difficult to
clean the top of solar cell, do not touch them with a finger, etc.
<Procedure>
(1) Insert either side of the solar cell under the
hook of the solar cell supporter, and then
insert the opposite side under the hook simi-
larly.
(2) Similarly to the solar cell, insert either side of
the hour wheel guard under the hook, and
then insert the opposite side under the hook.
(3) After assembling the solar cell supporter,
solar cell, and hour wheel guard, install them
to the movement.

B. Función del reloj de energía solar
Si la carga se vuelve insuficiente, una función de aviso entra en operación y la indicación cambia
de la siguiente manera.
■Función de aviso de carga insuficienteEsta función indica cuando la manecilla de
segundos cambia desde el movimiento en
intervalos de 1 segundo a un movimiento a
intervalos de 2 segundos. Cuando esto
ocurre, cargue rápidamente su reloj.
Además, la funciones de cronógrafo y alarma
no funcionarán en esta condición.
Aun en tal caso, el reloj mantiene la hora correc-
ta, pero si pasan aproximadamente 4 días
desde que comienza el intervalo de dos segun-
dos, el reloj dejaráde funcionar.
Después de exponer el reloj a la luz, se realiza
la recarga y el reloj vuelve al movimiento a inter-
valos de un segundo.
■Función de inicio rápido
El reloj se detendrási estácompletamente descargado.
El reloj comenzaráa funcionar tan pronto después de exponerlo (unos 10 segundos) a la
luz.
(Sin embargo, el tiempo que tome para comenzar varía según la claridad de la luz.)
■Función de prevención de sobrecarga
Cuando la batería secundaria se carga completamente como resultado de que una luz brillante
estáincidiendo sobre el cuadrante del reloj (celda solar), la función de prevención de sobrecar-
ga se activa automáticamente para evitar que la batería secundaria sea cargada adicional-
mente. Esto evita que la batería secundaria asícomo también la precisión de indicación de
hora, funciones y rendimiento del reloj se deterioren sin considerar cuanto se carga el reloj.
