Frequently Asked Questions - 7C17 SEIKO

How do I set the time on my Seiko 7C17 watch?

Pull the crown out to the second position (fully extended). Turn the crown clockwise or counterclockwise to set the correct time. Push the crown back in to the normal position.

How do I change the date on my Seiko 7C17?

Pull the crown out to the first position (one click). Turn the crown clockwise to adjust the date. Avoid setting the date between 9 PM and 3 AM to prevent damage to the movement.

What type of battery does the Seiko 7C17 use?

The Seiko 7C17 typically uses a SR920SW (or equivalent) silver oxide battery. Replaces every 2-3 years.

Is the Seiko 7C17 water resistant?

Yes, it is water resistant to 30 meters (3 ATM). Suitable for splashes and brief immersion, but not for swimming or diving.

How can I replace the battery myself?

Battery replacement should be done by a professional watchmaker to maintain water resistance. The case back needs to be opened carefully and the gasket should be checked.

What does the crown do on the Seiko 7C17?

The crown has three positions: normal (worn), first click (date adjustment), second click (time setting). It also serves to wind the watch if it is an automatic, but the 7C17 is quartz, so no winding.

How do I clean my Seiko 7C17?

Clean the watch case and metal bracelet with a soft, damp cloth. Avoid using chemicals or abrasives. For leather straps, use a leather cleaner.

Why did my Seiko 7C17 stop running?

The most common reason is a depleted battery. Replace the battery. If it still doesn't work, there may be a mechanical issue; consult a watchmaker.

Can I wear my Seiko 7C17 while showering?

It is not recommended. Although water resistant to 30m, showering may expose it to soap and steam, which can degrade the gaskets over time.

Where can I find a service manual for the Seiko 7C17?

Service manuals are typically available from Seiko distributors or online. You can also search for 'Seiko 7C17 service manual PDF' on the internet.

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.

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.

●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.

■TEMPERATURES

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

Temperatures over 60°C (140°F) may cause battery leakage or shorten the battery life. Do not leave your watch in very low temperatures below -10°C (+14°F) 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
