SOLAR CHARGING FUNCTION

Power Source
The battery used in this watch is a special secondary battery, which is different from ordinary
batteries.
Unlike an ordinary silver oxide battery, the secondary battery does not require periodic
replacement.
The capacity or charging efficiency may gradually lower due to long-term use or operating
environment.
In addition, long-term use may shorten the charge duration due to wear, contamination, lubricant
deterioration of mechanical parts, etc. Request repair when the performance lowers.
bWARNING
■ Notes on replacing the secondary battery
• Do not remove the secondary battery from the watch.
Replacement of the secondary battery requires professional knowledge and skill.
Please ask the retailer from whom the watch was purchased for replacement of the
secondary battery.
• Installation of an ordinary silver oxide battery can generate heat that can cause
bursting and ignition.
EN 21
3
TO PRESERVE THE QUALITY OF YOUR WATCH
* Overcharge prevention function
When the secondary battery is fully charged, the overcharge prevention function is automatically
activated to avoid further charging.
There is no need to worry 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.”
* For the required time to fully charge the battery, see “Guide to charging times” → P.18.
bWARNING
■ Notes on charging the watch
•When charging the watch, do not place the 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 50°C.
EN 22

TO PRESERVE THE QUALITY OF YOUR WATCH
Daily care
●The watch requires good daily care
• Do not wash the watch when its crown is in the extended position.
• Wipe away moisture, sweat or dirt with a soft cloth.
• After soaking the watch in seawater, be sure to wash the watch in clean pure water and wipe it dry
carefully.
Do not pour running water directly from a faucet onto the watch. Put some water into a bowl first, and
then soak the watch in the water to wash it.
* If your watch is rated as “Non-water resistant” or “water resistant for daily use,” please do not wash the watch.
“Performance and type” → P.24
“Water resistant performance” → P.26

TO PRESERVE THE QUALITY OF YOUR WATCH

Lumibrite
If your watch has Lumibrite
Lumibrite is a luminous paint that absorbs the light energy of sunlight and lighting apparatuses in a short
time and stores it to emit light in the dark. For example, if exposed to a light of more than 500 lux for
approximately 10 minutes, Lumibrite can emit light for 3 to 5 hours. Please note, however, that, as Lumibrite
emits the light it stores, the luminance level of the light decreases gradually over time. The duration of the
emitted light may also differ slightly depending on such factors as the brightness of the place where the
watch is exposed to light and the distance from the light source to the watch.
* In general, when coming from a place that is bright to a place that is dark, it takes human eyes some time to adapt
to the darkness making it difficult to see objects initially. (Dark adaptation)
* Lumibrite is luminous paint that stores and emits light, which is harmless to human beings and the environment,
containing no toxic materials such as radioactive substances.

Band
The band touches the skin directly and becomes dirty with sweat or dust. Therefore, lack of care
may accelerate deterioration of the band or cause skin irritation or stain on the sleeve edge.
The watch requires a lot of attention for long usage.
●Metallic band
•Moisture, sweat or soil will cause rust even on a stainless steel band if they are left for a long time.
•Lack of care may result in a rash or cause a yellowish or gold stain on the lower sleeve edge of shirts.
• Wipe off moisture, sweat or soil with a soft cloth as soon as possible.
• To clean the soil around the joint gaps of the band, wipe it out in water and then brush it off with a soft
toothbrush.
(Protect the watch body from water splashes by wrapping it up in plastic wrap etc.)
Clean it off with a soft cloth.
• Because some titan bands use pins made of stainless steel, which has outstanding strength, rust may
form in the stainless steel parts.
• If rust advances, pins may poke out or drop out, and the watch case may fall off the band, or the clasp
may not open.
• If a pin is poking out, personal injury may result. In such a case, refrain from using the watch and request
repair.
EN 29
3
TO PRESERVE THE QUALITY OF YOUR WATCH
●Leather band
•A leather band is susceptible to discoloration and deterioration from moisture, sweat and direct sunlight.
• Wipe off moisture and sweat as soon as possible by gently blotting them up with a dry cloth.
• Do not expose the watch to direct sunlight for a long time.
• Please take care when wearing a watch with light-colored band, as dirt is likely to show up.
•
Refrain from wearing a leather band watch other than Aqua Free bands while bathing, swimming, and
when working with water even if the watch itself is water resistant enforced for daily use (10-BAR/20-BAR
water resistant).
●Polyurethane band
• A polyurethane band is susceptible to discoloration from light, and may be deteriorated by solvent or
atmospheric humidity.
• Especially a translucent, white, or pale colored band easily adsorbs other colors, resulting in color smears
or discoloration.
• Wash out dirt in water and clean it off with a dry cloth.
(Protect the watch body from water splashes by wrapping it up in plastic wrap etc.)
• When the band becomes less flexible, have the band replaced with a new one. If you continue to use
the band as it is, the band may develop cracks or become brittle over time.
Notes on skin
irritation and
allergy
Skin irritation caused by a band may result from various factors such as allergy to
metals or leathers, or skin reactions against friction on dust or the band itself.
Notes on the
length of the band
Adjust the band to allow a little clearance with your wrist to ensure proper
airflow.
When wearing the watch, leave enough room to insert a finger between
the band and your wrist.

●Inspection and adjustment by disassembly and cleaning (Overhaul)
• Periodic inspection and adjustment by disassembly and cleaning (overhaul) is recommended
approximately once every 3 to 4 years in order to maintain optimal performance of the watch for a long
time. According to use conditions, the oil retaining condition of your watch mechanical parts may
deteriorate, abrasion of the parts may occur due to contamination of oil, which may ultimately lead the
watch itself to stop.
As the parts such as gasket may deteriorate, water-resistant performance may be impaired due to
intrusion of perspiration and moisture.
Please contact the retailer from whom the watch was purchased for inspection and adjustment by
disassembly and cleaning (overhaul). For replacement of parts, please specify “SEIKO GENUINE
PARTS.” When asking for inspection and adjustment by disassembly and cleaning (overhaul), make
sure that the gasket and push pin are also replaced with new ones.
• When your watch is inspected and adjusted by disassembly and cleaning (overhauled), the movement
of your watch may be replaced.

clothing when you wear it and it is not
sufficiently exposed to light.
Sufficiently charge the battery until it
reaches stable hand movement.
When you wear the watch, try to make
sure that the watch is not hidden by
your sleeves or other clothing.
Additionally, when you take the watch
off, try to place it in a bright place.
