How often should I replace the battery in my Seiko 4F32?

The battery (SR920SW) typically lasts 3 years. Replace it at an authorized service center to maintain water resistance.

Is the Seiko 4F32 suitable for swimming?

Yes, it has a water resistance of 10 bar (100 meters), making it suitable for swimming, snorkeling, and showering. Avoid hot water and pressing buttons underwater.

How do I set the date on my Seiko 4F32?

Pull the crown out to the first position and rotate it clockwise to set the date. Avoid setting the date between 9 PM and 4 AM to prevent damage.

The second hand moves in 2-second intervals. What does this mean?

This indicates the battery is low. Replace the battery as soon as possible to maintain accuracy.

Can I wear my Seiko 4F32 while playing sports?

Yes, it is designed for everyday wear and can withstand moderate impact. However, avoid high-impact sports like golf that may damage the movement.

How do I clean my Seiko 4F32?

Use a soft, lint-free cloth slightly dampened with water. Dry thoroughly. For metal bracelets, use a soft toothbrush with mild soap. Avoid abrasive cleaners.

What is the accuracy of the Seiko 4F32?

The quartz movement is accurate to within ±15 seconds per month under normal conditions.

How do I adjust the time?

Pull the crown to the second position (fully out) and rotate it to set the time. Push back in after setting to ensure water resistance.

What should I do if my watch stops?

First, check if the crown is fully pushed in. If it stops, the battery may be dead. Replace the battery at an authorized service center to avoid moisture entry.

PERPETUAL CALENDAR

• Once set, the calendar automatically adjusts for odd and even months including February of leap years up to February 28, 2100.
• It indicates the month, date, day of the week (Cal. 8F33) and the number of years since the last leap year.

HIGH ACCURACY

- Loss/gain: Annual rate of less than 20 seconds

Before using the watch:

• Because the calendar is preadjusted at the factory, you only need to set the time, date and day (Cal. 8F33), and the calendar will automatically update itself.
• Before using the watch, be sure to read "HOW TO CHECK THE CALENDAR", and then, set the time, date and day (Cal. 8F33) correctly following the procedures in "TIME/DATE SETTING" and "DAY SETTING".

* In case the calendar indication is not correct after the time/date setting is made, consult the retailer from whom the watch was purchased or an AUTHORIZED SEIKO DEALER.

1. Leap year indication

The second hand moves quickly at five-second intervals and stops to indicate the number of years that have passed since the last leap year. Before pulling out the crown to the first click, check and remember where the second hand is so that you can read how many seconds it has advanced.

NOTES ON USING THE WATCH

HOW TO OPERATE THE SCREW LOCK TYPE CROWN (for models with screw lock type crown)

• To unscrew the crown:

Turn the crown counterclockwise. (Then, pull it out for setting the time or checking the calendar)

• To screw in the crown:

With the crown at the normal position, turn it clockwise while pressing it.

TIME, DATE AND DAY SETTING

- When setting the date and day, turn the crown counterclockwise to advance the date and day and clockwise to move them back. The date and day change one day by turning the hour hand two full circles.

TIME/DATE SETTING

- The date changes between 11:45 p.m. and 0:30 a.m. while the watch is in operation and between 9:00 p.m. and 3:00 a.m. when it is changed manually by turning the hands. Therefore, note the following.

[AM/PM checking]

When setting the hour hand, check that AM/PM is correctly set.

* When setting the time by advancing the hands, turn the hour hand past the 3 o'clock marker. If the date advances, the time is set for the AM period. If it does not change, the time is set for the PM period.
* When setting the time by turning back the hands, turn the hour hand past the 9 o'clock marker. If the date moves back, the time is set for the PM period. If it does not change, the time is set for the AM period.

[Setting the time between 9:00 p.m. and 3:00 a.m.]

* If the time is adjusted to the time period between 9:00 p.m. and 3:00 a.m., the date may not change properly. The watch, however, will indicate the date properly after 3:00 a.m.
* To prevent this from occurring, first turn back the hour hand past 9:00 p.m., checking that the date moves back to the previous day, and then, advance the hands to the desired time.

- When setting the minute hand, advance it 4 to 5 minutes ahead of the desired time and then turn it back to the exact time.

DAY SETTING

• The day changes between 11:00 p.m. and 4:00 a.m. while the watch is in operation and also when it is changed manually by turning the hands.
• Do not change the day between 10:00 p.m. and 5:00 a.m. Otherwise, it may not change properly. If it is necessary to set the day during that time period, first change the time to any time outside it, set the day and then reset the correct time.

HOW TO CHECK THE CALENDAR

• If the crown is pulled out to the second click instead of the first click and pushed back in to the normal position, the watch will not show the calendar.
• Do not leave the crown at the first or second click when you use the watch, as this will shorten the battery life.

• Note on the leap second

One day normally is said to consist of 86,400 seconds. In fact, it can be longer or shorter than this because of irregular changes in the rotation cycle of the earth. When the accumulated fluctuations in the length of a day total plus or minus one second, one

second must then be added or subtracted as a correction factor. This is known as a "leap second".

The leap second correction is executed every year or two simultaneously throughout the world on the basis of information collected by astronomical observatories all over the world. The correction is effected between 11:59'59" p.m. and 0:00'00" a.m. GMT either on December 31 or on June 30, during which one second is added or subtracted.

When this happens, please adjust your watch accordingly.

Please refer to your newspaper for information on the leap second.

BATTERY CHANGE

[Cal. 4F32]

[Cal. 8F32, 8F33]

The miniature battery which powers your watch should last approximately 5 years (Cal. 4F32) / 10 years (Cal. 8F32 and 8F33). 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 CR1612 (Cal. 4F32) / SEIKO CR2412 (Cal. 8F32 and 8F33) battery.

* If the calendar checking function is used frequently, the battery life may be less than the specified period.

- Battery life indicator

When the second hand starts moving at two-second intervals instead of the normal one-second interval, replace the battery with a new one as soon as possible. Otherwise, the watch will stop operating in two weeks.

* The time accuracy is not affected even if the second hand is moving at two-second intervals.
* While the second hand is moving at two-second intervals, the watch will not show the calendar even if the crown is pulled out to the first click.

- Checking and adjustment of the calendar after battery change

The calendar function is not affected by battery changes. However, after the battery is replaced with a new one, be sure to check that the calendar is correct. (See "HOW TO CHECK THE CALENDAR")

If the watch does not indicate the leap year, month and date correctly, have the watch adjusted by an AUTHORIZED SEIKO DEALER.

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.

CAUTION

• Never short-circuit, heat or otherwise tamper with the battery, and never expose it to fire. The battery may burst, become very hot or catch fire.
• The battery is not rechargeable. Never attempt to recharge it, as this may cause battery leakage or damage to the battery.
