§2. SPECIFICATIONS

§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.]

•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

A. Setting the Time and Calendar

[1] Three-hand model without calendar display

* If your watch has a screw-type crown, lift up the crown to loosen it before operation. Be sure to

press the crown down firmly after operation.

■Setting the time

1. Pull the crown out to time setting position when the second hand reaches the 0 seconds posi-

tion.

2. Set the time by turning the crown.

3. Securely return the crown to normal position in synchronization with a telephone or other time

service.

[2] Models with calendar (date and day of the week) display

* If your watch has a screw-type crown, lift up the crown to loosen it before operation. Be sure to

press the crown down firmly after operation.

■Setting the time

1. Pull the crown out to the time setting position when the second hand reaches the 0 seconds

position.

2. Turn the crown to set the time.

•The date changes at 12:00 AM. Pay attention to AM and PM when setting the time.

3. Securely push in the crown to the normal position in synchronization with a telephone or other

time service.

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.

* Date display models ..... between 9:00 pm and 1:00 am

* Date, day of the week display models .... between 9:00 pm and 4:00 am

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.

C. Time Required for Recharge

Time required for recharge may vary according to the Caliber number, design (color of the dial,

etc.) and operating environment. The following table will serve you as rough reference.

“The recharging time is the time when the watch is continuously exposed to radiation.”

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

1. When removing the setting stem from the case

•Pressing down the end of the unlocking lever for setting stem from above, pull out the setting

stem.

(1) Set the crown at the normal position (Push it

in).

(2) Lightly press the end of the unlocking lever

for setting stem with a screwdriver, etc. from

above.

(3) With the lever pressed, pull out the setting

stem.

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.

(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.

(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.
