Frequently Asked Questions - 4J27 ANALOG QUARTZ SEIKO

How to set the time on my SEIKO 4J27 watch?

Pull the crown to position 2 (click). Turn it in the desired direction to advance or reverse the hands. Push the crown back to the initial position (pushed) to start the watch.

My watch stops, what should I do?

The battery is probably dead. Replace the battery (type SR920SW) by a professional watchmaker. Do not open the case yourself.

Can I wear my watch in the shower?

The 3 bar (30 m) water resistance allows splash resistance, but it is not recommended to wear it in the shower or while swimming.

How to change the strap on my SEIKO watch?

Use a strap changing tool or a fine screwdriver to remove the spring bars. Insert the new spring bars into the case holes. If necessary, consult a watchmaker.

The watch is losing or gaining time, is this normal?

A variation of a few seconds per day is normal for a quartz movement. If the difference is significant, the watch may require adjustment by a watchmaker.

How to clean my SEIKO watch?

Use a soft dry cloth. For leather straps, avoid water. For metal straps, gentle cleaning with a damp cloth is possible, then dry thoroughly.

What to do if the second hand does not move?

Check that the crown is fully pushed in. If it is in the pulled position, the second hand may be stopped. If the problem persists, the battery may be drained or the movement damaged.

Is the watch antimagnetic?

Standard quartz watches are not specially antimagnetic. Avoid exposure to strong magnetic fields (magnets, speakers) as they can affect accuracy.

Where to find the full manual for the 4J27 watch?

You can download the manual in PDF format on our site notice-facile.com, or request a printed version from your dealer.

How to maintain my SEIKO watch in the long term?

Have the water resistance checked and the battery replaced every 2-3 years. Regularly clean the case and strap. Avoid shocks and extreme temperatures.

TIME SETTING

CROWN

1 Pull out.
2 Turn to set the hour and minute
hands.
3 Push back in to normal position.

Read the time.

Touch the hands with your fingers.

NOTES

1 When touching the hands, take care not to move or damage them.

REMARKS ON USING THE WATCH

This watch is not water resistant, and care should be taken not to get it wet.

Also, do not touch the hour and minute hands with wet fingers, as this will adversely affect the time accuracy.

If the watch becomes wet, have it checked by an AUTHORIZED SEIKO DEALER or SERVICE CENTER.

• As the front cover is opened and closed every time you read the time, we recommend that the push pin supporting it be replaced with a new one once a year.

BATTERY CHANGE

Cal.2A27& Cal.4J27

Cal. 7C17

The miniature battery which powers your watch should last approximately 2 years (Cal. 2A27 and Cal. 4J27) / 5 years (Cal. 7C17). However, because the battery is inserted at the factory to check the function and performance of the watch, its actual life once in your possession may be less than the specified period. When the battery expires, be sure to replace it as soon as possible to prevent any malfunction. For battery replacement, we recommend that you contact an AUTHORIZED SEIKO DEALER and request SEIKO SR621SW (Cal. 2A27) / SEIKO SR521SW (Cal. 4J27) / SEIKO SR43SW (Cal. 7C17) battery.

WARNING

• Do not remove the battery from the watch.
• If it is necessary to take out the battery, keep it out of the reach of children. If a child swallows it, consult a doctor immediately.
• Never short-circuit, tamper with or heat the battery, and never expose it to fire. The battery may burst, become very hot or catch fire.

CAUTION

• The battery is not rechargeable. Never attempt to recharge it, as this may cause battery leakage or damage to the battery.

TO PRESERVE THE QUALITY OF YOUR WATCH

TEMPERATURES

Your watch works with stable accuracy within a temperature range of 5^ and 35^ (41°F and 95°F).

Temperatures over 60^ (140^) may cause battery leakage or shorten the battery life. Do not leave your watch in very low temperatures below -10^ (+14^) for a long time since the cold may cause a slight time loss or gain.

However, the above conditions will be corrected when the watch returns to normal temperature.

SHOCKS & VIBRATION

Light activities will not affect your watch, but be careful not to drop your watch or hit it against hard surfaces, as this may cause damage.

MAGNETISM

Your watch will be adversely affected by strong magnetism. Keep it away from close contact with magnetic objects.

CARE OF CASE AND BRACELET

To prevent possible rusting of the case and bracelet caused by dust, moisture and perspiration, wipe them periodically with a soft dry cloth.

PERIODIC CHECK

It is recommended that the watch be checked once every 2 to 3 years. Have your watch checked by an AUTHORIZED

SEIKO DEALER or SERVICE CENTER to ensure that the case, crown, gasket and crystal seal remain intact.

CHEMICALS

Be careful not to expose the watch to solvents (e.g., alcohol and gasoline), mercury (i.e., from a broken thermometer),

cosmetic spray, detergents, adhesives or paints. Otherwise, the case, bracelet, etc. may become discolored, deteriorated or damaged.

PRECAUTION REGARDING CASE BACK PROTECTIVE FILM

If your watch has a protective film and/or a sticker on the case back, be sure to peel them off before using your watch.

Otherwise, perspiration getting in under them may rust the case back.
