EN 4

b WARNING

HOW TO USE

Do not use the watch in scuba diving or saturation diving.
The various tightened inspections under simulated harsh environment, which are usually required for watches designed for scuba diving or saturation diving, have not been conducted on the water resistant watch with the BAR (barometric pressure) display. For diving, use watches specifically designed for diving.

b CAUTION
Do not pour running water directly from faucet. The water pressure of tap water from a faucet is high enough to degrade the water resistant performance of a water resistant watch for everyday life.

EN 6

b CAUTION

Please note that there is a risk of minor injury or material damage if the following safety regulations are not strictly observed.

HOW TO USE

Avoid the following places for wearing or keeping the watch:

Places where volatile agents (cosmetics such as polish remover, bug repellent, thinners etc.) are

vaporizing

Places where the temperature drops below Places affected by strong vibrations

5°C or rises above 35°C for a long time

Places of high humidity

Places affected by strong magnetism or static Dusty places

electricity

If you observe any allergic symptoms or skin irritation Stop wearing the watch immediately and consult a specialist such as a dermatologist or an allergist.

Other cautions
For adjusting the length of the metallic band, specialized knowledge and expertise are necessary. Therefore, in such a case, contact the retailer from whom the watch was purchased. If you attempt to adjust the metallic band, injury may occur to your hand or fingers, or parts of the band may be lost.
Do not disassemble or tamper with the watch. Keep the watch out of the reach of babies and children. Extra care should be taken to avoid risks
of any injury or allergic rash or itching that may be caused when they touch the watch. When disposing of used batteries, follow the instructions of your local authorities. If your watch is of the fob or pendant type, the strap or chain attached to the watch may damage
your clothes, or injure the hand, neck, or other parts of your body.

EN 5

b CAUTION

Please note that there is a risk of minor injury or material damage if the following safety regulations are not strictly observed.

HOW TO USE

Do not turn or pull out the crown when the watch is wet.
Water may get inside of the watch. * If the inner surface of the glass is clouded with condensation or water droplets appear
inside of the watch for a long time, the water resistant performance of the watch is deteriorated. Immediately consult the retailer from whom the watch was purchased or SEIKO CUSTOMER SERVICE CENTER.

Do not leave moisture, sweat and dirt on the watch for a long time.
Be aware of a risk that a water resistant watch may lessen its water resistant performance because of deterioration of the adhesive on the glass or gasket, or the development of rust on stainless steel.

Steam, soap or some components of a hot spring may accelerate the deterioration of water resistant performance of the watch.

EN 7

Characteristics

HOW TO USE

This solar watch is equipped with a stopwatch function. · A full-scale stopwatch, which can measure in 1/5-second increments (V172, V174, V175) or 1/20-second
increments (V176) with the center hand, is equipped. · A solar cell under the dial converts any form of light into "electrical energy" to operate the watch.
* "Chronograph" means a watch with a stopwatch function.

Stopwatch function.................. The stopwatch can measure up to 60 minutes in 1/5-second

P.22

increments (V172, V174, V175) or 1/20-second increments (V176).

After measuring 60 minutes, the stopwatch will automatically stop.

Alarm function.......................... The single-time alarm can be set to sound only once at a designated

P.34

time.

The alarm time can be set in one-minute increments to the time until

11 hours 59 minutes is reached.

(Only available for V172 and V174)

Solar Charging Function..........The watch charges by converting light that shines on the solar panel

P.37

on the dial into electrical energy. After the battery is fully charged,

the watch will operate for about six months even if the dial is not

exposed to light.

SOLAR CHARGING FUNCTION

The figures of "Time required for charging the watch to start moving at one-second intervals" are estimations of time required to charge the stopped watch by exposing it to light until it moves at steady one-second intervals. Even if the watch is partially charged for a shorter period, the watch will resume one-second interval movement. However, it may shortly return to two-second interval movement. Use the charging time in this column as a rough guide for sufficient charging time.
* The required charging time slightly varies depending on the model of the watch.

TO PRESERVE THE QUALITY OF YOUR WATCH

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.

b WARNING

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 40

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.

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.

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.
