Frequently Asked Questions - 4N30 SEIKO

How do I set the time on my Seiko 4N30 watch?

Pull the crown out all the way. For models with three hands, pull out when the second hand points to 12 o'clock. Turn the crown to adjust the time, then push the crown back in. For quartz watches, advance the minute hand a few minutes ahead and then turn back to exact time.

How do I set the date on my watch?

Pull the crown to the first click. Turn it until the previous day's date appears. Then pull to the second click and advance the hands until the desired date appears. Avoid setting the date between 8 PM and 4 AM.

What type of battery does the Seiko 4N30 use?

The watch uses a Seiko genuine battery. For replacement, contact an authorized Seiko dealer to ensure correct battery and prevent malfunction.

How do I know when the battery needs replacing?

If your watch has a second hand and it starts moving in two-second increments instead of one-second, the battery is low and should be replaced soon.

Is my Seiko 4N30 watch water resistant?

Water resistance varies by model. Check the case back inscription. If it says 'WATER RESISTANT', it can withstand splashes. If '5 BAR', suitable for swimming. Do not operate crown underwater.

How do I operate a screw-down crown?

To unlock, turn the crown counterclockwise until it pops out. To lock, push the crown in fully and turn clockwise until it tightens. Ensure it is locked before water exposure.

How often should I have my watch serviced?

It is recommended to have your watch checked every 2-3 years by an authorized Seiko dealer to maintain integrity of case, crown, gasket, and crystal.

Can I wear my watch in extreme temperatures?

Avoid temperatures above 60°C (140°F) or below -10°C (14°F) for extended periods, as it may affect battery life or accuracy. Normal function resumes when temperature normalizes.

How do I clean my Seiko watch?

Wipe the case and bracelet with a soft dry cloth regularly to remove dust and perspiration. Avoid contact with solvents, cosmetics, or detergents.

What should I do if my watch stops?

For mechanical models, swing the watch side to side for 30 seconds or wind the crown if applicable. For quartz models, replace the battery. If problem persists, consult an authorized dealer.

Notes on calendar setting:

1 Do not change the calendar between 8:00 P.M. and 4:00 A.M, as it may not change properly. If it is necessary to set the calendar during that time period, first change the time to any time outside those hours, set the calendar and then reset the correct time.
2 When the day shifts automatically to the next day, the other language will temporarily appear.

3 When setting the hour hand, check that AM/PM is correctly set. The watch is so designed that the calendar changes once every 24 hours.
Turn the hands past the 12 o'clock marker to determine whether the time is set for the A.M. or P.M. period. If the calendar changes, the time is set for the A.M. period. If it does not change, the time is set for the P.M. period.

CHANGING BATTERY IN ANALOGUE QUARTZ WATCH

Because the battery is inserted at the factory to check the function and performance of the watch, its actual service life once in your possession may be less than the specified period. When the battery expires, make 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 they only use a genuine SEIKO battery.

● Battery life indicator

If your analogue quartz watch has a second hand, the battery needs to be replaced when you see the second hand moving in two-second increments instead of the normal one-second increments. (Some calibres do not have this function.) The watch will, however, remain accurate while the second hand is moving in two-second increments.

LOSS/GAIN OF THE ANALOGUE QUARTZ WATCH

Loss/gain (monthly rate) is less than 15 seconds (20 seconds for some calibres) in the normal temperature range ( 5^ C \~ 35^ C or 41^ F \~ 95^ F).

TO PRESERVE THE QUALITY OF YOUR WATCH

WATER RESISTANCE

● Non-water resistance

If "WATER RESISTANT" is not inscribed on the case back, your watch is not water resistant, and

care should be taken not to get it wet as water may damage the movement. If the watch becomes wet, we suggest that you have it checked by an AUTHORIZED SEIKO DEALER or SERVICE CENTER.

● Water resistance (3 bar)

If "WATER RESISTANT" is inscribed on the case back, your watch is designed and

manufactured to withstand up to 3 bar, such as acci dental contact with splashes of water or rain, but it is not designed for wearing while swimming or diving.

● Water resistance (5 bar)\*

If "WATER RESISTANT 5 BAR" is inscribed on the case back, your watch is designed and

manu-factured to withstand up to 5 bar and is suitable for wearing while swimming, yachting and taking a shower.

● Water resistance

10 bar/15 bar/20 bar)\*

If "WATER RESISTANT 10 BAR", "WATER RESISTANT 15 BAR"

or "WATER RESISTANT 20 BAR" is inscribed on the case back, your watch is designed and manufactured to withstand up to 10 bar/15 bar/20 bar, respectively, and is suitable for wearing while taking a bath or shallow diving, but not for scuba diving. We recommend that you wear a SEIKO Diver's watch while scuba diving.

Before using a water resistant 5, 10, 15 or 20 bar watch in water, make sure the crown is pushed in completely.
Do not operate the crown when the watch is wet or in water. If used in sea water, rinse the watch in fresh water and dry it completely.
When taking a shower while wearing a water resistant 5 bar watch, or taking a bath while wearing a water resistant 10, 15 or 20 bar watch, make sure to observe the following:
- Do not operate the crown when the watch is wet with soapy water or shampoo.
- If the watch is left in warm water, a slight time loss or gain may be caused. This condition, however, will be corrected when the watch returns to normal temperature.

NOTE:

Pressure in bar is a test pressure and should not be considered as corresponding to an actual diving depth since swimming movements tend to increase the pressure at a given depth. Care should also be taken when wearing and diving into water.

■ TEMPERATURE RANGE

[for analogue quartz watches only]

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

Temperatures over 60°C or 140°F (50°C or 122°F for some calibres) may cause battery leakage or shorten the battery life.

Do not leave your watch in very low temperatures below -10^ or +14^ (-5°C or +23^ for some calibres) 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.

General 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

The watch will be adversely affected by strong magnetism. Keep the watch away from close contact with magnetic objects. (In the case of a

quartz watch, normal accuracy will return if t watch is moved away from the magnetic field.)

■ 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.

■ 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.

CHEMICALS

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

broken thermometer), cosmetic sprays, detergents, adhesives or paints, as the case, bracelet, etc. may become discolored, deteriorate or damaged.

■ PRECAUTION REGARDING CASE BACK PROTECTIVE FILM

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

before using your watch. Otherwise, perspiration getting under them may rust the case back.
