3. SOLAR POWER WATCH
This watch is powered not by an ordinary battery, but by converting light energy into
electrical energy.
A rechargeable battery is used in this watch to store electrical energy. This secondary
battery is a clean energy battery that doesn't use any toxic substances such as mercury.
Once fully charged, the watch will continue to run for approximately 6 months without
further charging.
• 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
rechargeable battery may not be charged sufficiently. If so, additional charging
may be necessary when not worn.
• The watch should be put on a well-lit place as long as possible for its normal
operation while it is not worn.
The watch should be exposed to light each day to ensure the watch has a sufficient charge
for proper operation. Please note that if the user wears long sleeves, the watch can
easily become insufficiently charged as it is hidden from light. Be sure to expose your
watch to light daily for a period sufficient to maintain a proper charge.

4. Setting the Time
If your watch has a screw-type crown, unscrew the crown from the case loosen it before
operation. Be sure to press the crown down and screw in after setting the time and/or
date.
1. Stop the second hand by pulling the crown out to the 2nd click (time setting
position).
2. Turn the crown to set the time.
3. The watch will start after the crown is firmly pushed back into its normal position.
5. 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
• Quick Start Function
The second hand changes to two-second-
interval movement to indicate
insufficient recharging.
Even in such a case, the watch keeps
correct time, but about 1 week 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.
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.)
• Time Setting Warning Function
• Overcharging Prevention Function
If the watch stops, subsequent exposure to light
allows the 'quick start' function to start
again, and the second hand moves with a hitch to
indicate that the time incorrect.
In this case, quickly recharge the watch and
reset the time.
Even if the secondary battery is fully
recharged, the hitch movement will continue,
unless the time is reset and the crown is
returned to the normal position
Once the secondary battery is fully recharged, the overcharging prevention feature comes
into operation and prevents overcharging.

6. 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 an approximate
reference.

7. Notes on Recharge
Avoid recharging at high temperatures (over about 60"C/140'F), otherwise the watch will be
damaged during recharging.
(EG)
• Charging the watch near a light source that easily becomes hot, such as an
incandescent lamp or a halogen lamp.
• Charging in a place that easily becomes hot, such as a dashboard.
When you charge the watch by an incandescent lamp, take a distance about 50cm (20in.) from
the light source to prevent any damage to the movement or any components from the high
temperature radiated by incandescent light bulbs.
Please note that if the user wears long sleeves, the watch can easily become
insufficiently charged as it is hidden from light. Be sure to expose your watch to light
daily for a period sufficient to maintain a proper charge.

8. About the Eco Drive Rechargeable Battery
This watch uses the rechargeable battery, which does not have to be periodically replaced
due to repeated charging and discharging, unlike ordinary batteries.
However, certain maintenance, such as water testing and gasket checks should be performed
at regular intervals. The requirements will vary by model and features.
Caution
Never use a battery other than the Eco Drive Manganese Titanium rechargeable battery used
in this watch.
Installing a battery other than the original Eco Drive Manganese Titanium Rechargeable
battery may result in overcharging of the movement causing it to burst, which could result
in damage to the watch and even to the human body.

TEMPERATURE CARE
Avoid temperature extremes. Exposing your watch to high
temperatures, such as placing it on the dashboard of a vehicle
or use in a hot tub, may cause the watch to malfunction,
shorten battery life or damage certain components. Leaving
the watch in extreme cold temperatures may cause irregular
timekeeping until the watch returns to normal operating
temperature.
SHOCK-RESISTANT
The watch may be worn while playing golf or other activities,
but avoid severe shocks such as dropping it on a hard surface.
MAGNETIC-RESISTANT
No problem should occur from using the watch around
ordinary household electric appliances such as TV sets or
stereos. Keep away from magnets.
CHEMICAL/GAS RESISTANT
Do not expose the watch to chemicals or gases for long
periods.
WATCH CLEANING
Stains, waterspots and accumulated dirt on the case, crystal
or band should be removed with a soft cloth to prevent
damage and premature wear.
HANDLING OF WATER-RESISTANT WATCHES
Although water-resistant watches are warranted, steps should
be taken to avoid damage that may result from
accidents or mishandling:
■Do not operate the crown or push-button in the water or
while the watch is wet. Tighten screw lock crown completely.
■Should the watch become immersed in water, dry it off
right away. If the watch comes in contact with salt water, be
sure to rinse it thoroughly in warm fresh water to remove any
trace of salt.
■If a watch is wet from cleaning or by accident, never store it
in a closed container. It should be dried immediately or taken
to a watchmaker or jeweler if moisture is inside the case to
prevent damage from rust.
■Vital components necessary to resist the entrance of
moisture deteriorate with time and use. Gaskets, crowns and
other materials should be replaced every year or two to ensure
PRECAUTIONS ABOUT CARE AND
HANDLING OF WATCHES
that water resistant quality remains at factory specifications.
CARE FOR METAL BRACELETS
To extend the life and maintain the good appearance of the
metal watch bracelet, the following recommendations are
given:
■Be aware that since the watch and bracelet is worn next to
the skin, it collects dust and perspiration and becomes soiled if
not cleaned regularly. This is particularly true of the inner parts
of the links or mesh of the bracelet.
■Soil and rust, when present in a bracelet, are dissolved by
perspiration and can cause staining of cuffs and
irritation of the skin in some instances.
■Heavy perspiration should be wiped off the watch and
bracelet with a soft dry cloth. The bracelet should be cleaned
occasionally by using an old toothbrush and warm soapy
water after which the soap is thoroughly rinsed with clear water
and the bracelet dried completely. The foregoing manner of
cleaning should not be done if the watch is not water-resistant
but should instead be done by your jeweler.
CARE FOR STRAPS
LEATHER
■Heavy perspiration, if not removed from a leather strap, can
wash out the natural oils and cause the leather to become dry
and deteriorate. Any moisture should be blotted with a soft dry
cloth or paper towel and the strap allowed to dry naturally.
■Salt residue and soil can be removed from the leather by
cleaning with a dampened soft cloth and mild soap or saddle
soap.
■Occasionally, the inside surface of the strap should be
cleaned by using a soft cloth dampened with alcohol.
■The strap should always be worn a little loosely (one finger
space between wrist and strap) to allow air to circulate thus
causing any moisture to evaporate.
RUBBER
■Rubber straps should be washed frequently with mild soap
and warm water using a soft brush.
■Thorough cleaning, using the same method, should
especially be done after use in salt water.
■Solvents, oils, perspiration, tanning lotion and salt can cause
rubber to deteriorate if not removed.
