Remarks on the battery

The battery used in this watch is a special secondary battery, which is totally different from ordinary silver oxide batteries.

Unlike other disposable batteries such as dry-cell batteries or button cells, this secondary battery can be used over and over again by repeating the cycles of discharging and recharging.

However, for various reasons such as long-term use or usage conditions, the capacity or recharging efficiency of the secondary battery may gradually deteriorate. Worn or contaminated mechanical parts or degraded oils may also shorten recharging cycles. If the efficiency of the secondary battery decreases, have the watch repaired.

WARNING

Remarks on replacing the secondary battery

- Do not remove the secondary battery yourself. Replacement of the secondary battery requires professional knowledge and skill. Please ask a watch retailer for repair. - Installation of an ordinary silver oxide battery can generate heat that can cause bursting or ignition.

乘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".

※Refer to "Guideline of charging time" on page 54 to check the time required for fully charging the watch.

WARNING

Notes on charging the watch

- When recharging the watch, do not place it too close to incandescent light or other light sources as the watch temperature will become extremely high, causing damage to the parts inside the watch.

- When exposing the watch to sunlight to recharge it, do not leave it on the dashboard of a car, etc. for a long time, as the watch temperature becomes extremely high.

· Always keep the watch temperature under 50°C.

■ To preserve the quality of your watch

WARNING

- Immediately stop wearing the watch in the following cases :

○ if corrosion appears on the watch body or band, etc.

○ if the pins protrude from the band

※ Immediately consult the retailer from whom the watch was purchased or a SEIKO CUSTOMER SERVICE CENTER.

- Keep the watch and accessories out of the reach of babies and children.

Care should be taken to prevent a baby or a child accidentally swallowing any accessories.

· Do not remove the secondary battery from the watch.

※ About the secondary battery → Please refer to ■ REMARKS ON THE BATTERY

Replacement of the secondary battery requires professional knowledge and skill.

No Indication	Keep the watch more than 10 cm away from magnetic products.
	Keep the watch more than 5 cm away from magnetic products.(JIS level-1 standard)
	Keep the watch more than 1 cm away from magnetic products.(JIS level-2 standard)

If the watch becomes magnetized and its accuracy deteriorates to an extent exceeding the specified rate under normal use, the watch needs to be demagnetized. In this case, you will be charged for demagnetization and accuracy readjustment even if it happens within the guarantee period. The reason why watch is affected by magnetism. The built-in motor is provided with a magnet, which may be influenced by a strong external magnetic field.

●Daily care

The watch requires good daily care.

- Do not wash the watch when the crown is pull out.

· 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

※If your watch is rated as "non-water resistant" or "water resistant for daily use," do not wash the watch.

●Turn the crown

• To prevent rusting of the crown, please sometimes turning the crown.

- Please do the same for screw-lock type crown

●Water resistance

Refer the table below for the description of each degree of water resistant performance of your watch before using.

Indication on the case back	Water resistant performance	Condition of use
No indication	Non-water resistance	Avoid drops of water or sweat
WATER RESISTANT	Water resistance for everyday use	The watch can withstand accidental contact with water in everyday life.	Not suitable for swimming
WATER RESISTANT 5 BAR	Water resistance for everyday use at 5 barometric pressures.	The watch is suitable for sports such as swimming.
WATER RESISTANT 10(20)BAR	Water resistance for everyday use at 10 (20) barometric pressures.	The watch is suitable for diving not using an air cylinder.

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 a sleeve cuff. 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 cause a yellowish or gold stain on a sleeve cuff 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 and then brush it off with a soft toothbrush.

(Protect the watch body from water splashes by wrapping it in plastic wrap, etc.)

Because some titanium bracelets 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 bracelet, 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.

.eather band

A leather band is susceptible to discoloration and deterioration from moisture, sweat and direct sunlight.
Wipe off moisture and sweet as soon as possible by gently blotting with a dry cloth.
Do not expose the watch to direct sunlight for a long time.
Please take care when wearing a watch with a light-colored band.

as dirt or stains are likely to show.

- 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 water resistant).

Polyurethane band

A polyurethane band is susceptible to discoloration from light, and it 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 off dirt in water and clean the band with a dry cloth.
(Protect the watch body from water splashes by wrapping it 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.

Note on skin irritation and allergy:

Skin irritation caused by a band has various reasons such as an allergy to metals or leather, or skin reactions against friction or 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.
