Frequently Asked Questions - 6N43 SEIKO

How do I set the date on my Seiko 6N43?

Pull the crown to the first position (one click). Turn it clockwise to set the date. Push the crown back in when done. Avoid setting the date between 9 PM and 4 AM to prevent damage.

How do I set the time on my watch?

Pull the crown to the second position (two clicks). Turn it to set hour and minute hands. Push the crown back in after setting. Ensure the crown is fully pressed to maintain water resistance.

What battery does the Seiko 6N43 use?

It uses a SR626SW or equivalent silver oxide battery. Replace every 2–3 years or when the watch stops or runs slow.

Is my Seiko 6N43 water resistant?

Yes, it has a water resistance rating of 30 meters (3 ATM). It can handle splashes and rain but not swimming or diving. Always ensure the crown is pushed in.

How do I replace the battery?

Battery replacement is recommended by a professional. Open the caseback carefully (usually snap-off or screw-down). Replace with SR626SW and check gasket for water resistance. Improper handling may damage the movement.

Why is my watch losing time?

Low battery is the most common cause. If replacing the battery doesn't help, the watch may need servicing due to contamination or worn parts. Quartz watches are very accurate; a sudden loss typically signals battery end-of-life.

Can I wear my Seiko in the shower?

No, showering is not recommended. Even though it is water resistant to 30 meters, steam and soap can degrade seals and cause moisture ingress. The watch is only splash-proof.

How do I clean my watch?

Use a soft, lint-free cloth to wipe the case and crystal. For metal bands, use a damp cloth and mild soap. Avoid abrasive cleaners. Ensure the crown is pushed in to prevent water entry.

What does the crown position 0, 1, 2 mean?

Position 0 (pushed in) is normal running. Position 1 (first click) allows date quick-set. Position 2 (second click) allows time setting. Always push back to position 0 after adjustments.

Where can I get spare parts for my Seiko 6N43?

Spare parts such as straps, crystals, and batteries are available through authorized Seiko service centers. Third-party vendors may also offer compatible parts. Check the manual for part numbers.

HOW TO USE THE WATCH

Set the time/calendar following the instruction pertaining to your watch type.

TIME SETTING FOR MODELS WITHOUT CALENDAR

1. Pull out the crown all the way.
   * If your watch has three hands, pull out the crown when the second hand is pointing to 12 o'clock.
2. Adjust the time by turning the crown in the desired direction.
3. Push the crown back in to the normal position.
   * If your watch has three hands, push the crown back in to the normal position in accordance with a time signal for "00" seconds.

Note: When setting the minute hand of a quartz watch, advance it to a few minutes ahead of the time and then turn it back to the exact time.

TIME/CALENDAR SETTING FOR MODELS WITH CALENDAR

The date will change gradually between 9:00 P.M. and 4:00 A.M. (See note 1 on calendar setting.) For some models, however, it will change instantly when the hands pass the 12 o'clock marker at midnight.

● For models with date calendar

1. Pull out the crown to the first click.
2. Turn the crown until the previous day's date appears in the calendar frame.
3. Pull out the crown to the second click, and advance the hour and minute hands until the desired date appears.

Notes on calendar setting:

1 Do not change the calendar between 9:00 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.
