INTRODUCTION -About mechanical watch-

Thank you very much for purchasing the Grand Seiko mechanical watch.

Take hold of your watch softly.

Hear the watch ticking.

tick tock, tick tock, tick tock,

soft and faint. a dignified sound can be heard.

The sound can be called

the crystal of the craftsmen's spirit and skill.

Handpicked parts assembled one by one,

carefully, with craftsmanship.

giving life to a mechanical watch.

This is proven by the sound.

Talking about accuracy.

mechanical watches cannot be compared to

quartz watches, that is for certain.

However, the accuracy of a mechanical watch

is pursued by human hands.

Full of spirit and know-how of craftsmen.

A mechanical watch-complicated, sensitive,

and having a human touch.

We would like to let all of you know

the charm of a mechanical watch, which has no bounds.

So we made this handbook, mainly detailing the accuracy.

Wishing you will have a nice time

with your Grand Selko for a long, long time.

SEIKO WATCH CORPORATION

Quartz watches and mechanical watches - what is the difference?

We will explain by example

Quartz watches that you have come to be

Tamar with.

These are just like appliance, controls by computers.

A battery, C, and crystal make quartz watches work accurately. electrically.

Some loss or gain may occur while the

watch is worn.

However, this will be too small to voice in your daily life.

a quartz watch resembles an airplane.

a mechanical watch is like a bicycle.

All watch parts work together mechanically

to make it up.

Thus, a mechanical water is easily affected by the outside environment.

It is hot, the watch tends to lose time.

When power driving the watch becomes

short (when the amount the spring is

wound to anony, accuracy, becomes unstable.

If the resting position of the watch is

changed, successfully is also affected.

The rate of loss/gain could be significant that you will notice in your daily fee.

The accuracy is shown by the daily rate

This is called the daily rate.

The accuracy of a mechanical watch

is usually shown in this daily rate.

or the outside environment.

This,

By only observing less/gain in one day,

You cannot judge how absolute the watch works.

If you check the average of the daily loss/gain rate,

you can judge the accuracy of the watch.

In the case of quality watches, the accuracy is usually

gain rate of quartz watches

Characteristics of a mechanical watch

Mean daily rate / Normal usage accuracy

The accuracy of a mechanical watch varies depending on many things.

such as the amount, the spring is wound by movements of your arm, temperature, or resting position of the watch.

Thus to show the accuracy of a mechanical watch every, not depending on the environment, lost/gain of a mechanical watch is measured

before the inside movement of the water are put in the case,

under controlled conditions

with many days of tests.

AND THE DESIGNED SALE IS CHERE, MENTLY SALE.

In both the 803159 and Grand Selco Standard,

the standard rate is mean daily rate.

⇒ "THE GRAND SEKCI STANDARD PAGE 52"

Grid of nine analog clocks showing 8 o'clock symbols, likely for digital clock display or reading exercise

This rate is the data measured in an environment that is artificially controlled.

in order to fairly evaluate/show the abilities of mechanical watches without being influenced by environmental changes.

So it is different from "normal usage accuracy"

when you are actually wearing the watch.

The accuracy of a mechanical watch varies delicately day by day, depending on the environment.

This is like a living thing.

one of the charms that a mechanical watch has.

Normal usage accuracy should be from -1 secondary to -10 seconds (-1 to -18 seconds for Cal. 9635 and 9635, -5 to +10 seconds for Cal. 9625/day). If the average of the daily mass exceeds the level, we would like the responsibility for adjusting it, according to The cost of adjusting the watch is free of charge or three years from the case of purchase.)

To adjust the security as security as possible, information such as the rate of loss/gain of your watch and how you use I, are very important. Please let us know the following when you ask for adjustment of your watch by our service person:

(1) The average daily loss/gain rates for one week to ten days

Ex. an average of 11 seconds

(2) Approximate hours of wearing the watch in one day in the above period.

Ex. Reprodentary to France

(3) The seeing position of the Xach while you don't need it.

Characteristics of a mechanical watch For lifelong use of your mechanical watch

For lifelong use of your mechanical watch rule No.1

Wind the mainspring of your mechanical watch at a fixed time.

As there are rules for everything

there same for wincing the song.

"You have not heard this before?"

Please keep it in mind

The mainspring - the source of energy for a mechanical watch

After it is fully worried, I can supply the most stable energy to every part of the watch movement, and the accuracy of the watch becomes most stable.

Even if your watch is a self-winding type, when you feel the accuracy is not stable, shake the watch or turn the crown to wind the mainspring further.

If you work at a desk, etc., and do not move too much,

the spring will not be wound sufficiently.

If your watch is a wind-up mechanical type, turn the crown every day, at a fixed time to wind the mainspring sufficiently.

To use the watch with better accuracy, wind the mainspring every day, at a fixed time.

Please keep to this rule as best as possible.

For instance, You may make it a rule to win the spring When you wake up, or at lunchtime.

Which position should be seen to call it?

The loss/gain of a mechanical watch

devends on the rating position of the watch. In one position, the watch lands to gain another position, it doesn't.

For instance, while you are sleeping at night

For lifelong use of your mechanical watch rule No.3

Accuracy will vary depending on the temperature.

A piece of metal of about 0.1 mm, as thin as a hair, is wound.

That is the key that controls the accuracy of all mechanical watches.

Metals expand and contract depending on the temperature.

This characteristic of all metals also applies to the balance spring.

in other words.

When it is not, the balance spring exceeds and the watch tends to lose. When it is cold, the balance spring contracts and the watch tends to gain. This is typical.

For lifelong use of your mechanical watch rule No.4

Keep your mechanical watch away from magnetic objects.

After you take off your watch.

do you leave it by your call phone?

Or put it on a television or next to your PC?

Do you put it in your bag with your cell phone?

Watches do not like magnetism.

They may lose or gain when affected by magnetism.

To make your mechanical watch work more accurately.

it is important, not to leave the watch close to magnetic objects for a long time.

In particular, cell phones, televisions and speakers of PCs have strong magnetism.

■CAUTIONS FOR ACCURACY

Normal usage accuracy of a mechanical watch varies depending on individual customer's use conditions such as winding state of the mainspring by movement amount of the customer's arm per day, temperature environment, and position orientation of a watch. Accordingly, the actual normal usage accuracy when the watch is used by a customer may differ from the numerical value of each item specified in the Grand Save Standard.
The target range of normal usage accuracy when the watch is actually used by a customer is set to -1 to +10 seconds (-1 to +8 seconds for Cal. 9S86 and 9S85, -5 to +10 seconds for Cal. 9S25) per day.
To correctly judge the normal usage accuracy, please use the watch for not only one day, but also approximately one week to 10 days under normal use conditions to check one or gain of time. If the average value per day exceeds the target range, we will adjust the watch. (Adjustment is provided Free of charge for three years after purchase, then charged thereafter. For more deals, please refer to the instruction manual.)
The enclosed Grand Seiko Standard Inspection Certificate certifies the values of a movement single unit before assembly in a case which are measured under an artificially controlled environment in the production factory passed the Grand Seiko Standard Inspection.
Should the certificate be lost or after repair or adjustment, it cannot be released.

■ CAUTIONS ON WATER RESISTANCE

CAUTIONS

Do not turn or pull out the crown when the watch is wet.

Water may get inside of the watch. ※ If the inner surface of the glass is clouded with condensation or water droplets appear inside of the watch for a long line, the water resistant performance of the watch is deteriorated. Immediately consult the retailer from whom the watch was purchased or Grand Seiko international service network mentioned on CERTIFICATE OF GUARANTEE or our website.

Do not leave moisture, sweat and dirt on the watch for a long time.

Be aware of a risk that a water resistant watch may lessen its water resistant performance because of deterioration of the adhesive on the glass or gasket, or the development of rust on stainless steel.

Do not wear the watch while taking a bath or a sauna.

Steam, soap or some components of a hot spring may accelerate the deterioration of water resistant performance of the watch.

If water-resistant level of your watch is defined as "WATER RESISTANT"

WARNING

Do not use the watch in scuba diving or saturation diving.

The various tightened inspections under simulated harsh environment, which are usually required for watches designed for scuba diving or saturation diving, have not been conducted on the water-resistant watch with the BAR (barometric pressure) display. For diving, use special watches for diving.

CAUTION

Do not pour running water directly from the faucet.

The water pressure of tap water from a faucet is high enough to degrade the water resistant performance of a water resistant watch for everyday life.

HOW TO USE (FOR CAL. 9S85, 9S68, 9S65, 9S25)

How to wind the mainspring

- This watch is an automatic winding type (with manual winding function). - The mainspring can be sufficiently wound automatically by natural movement: of the arm while normally worn on the wrist. In addition, it can be wound by turning the crown.

☐ A stopped watch can be started by arm movement when it is worn on the wrist, however, before wearing the wosten, wind the mansping sufficiently and set the time and date. When winding the mansping, turn the crown at the normal position clockwise (12 o'clock direction) slowly. If you turn the crown counterclockwise (6 o'clock direction), it will turn free. The mansping is sufficiently wound when the crown is turned approximately 45 times (50 times for Cal. 9808 and 9805, 30 times for Cal. 9929). When the mansping is in the full-winding state, it is designed so that the mairspring slips IT is overwound. Therefore, it is not necessary to worry about breaking the mairspring, however, please retain from excessive operation.

It is recommended that you wear the watch on your wrist more than 10 hours a day to keep the mainspring wound up. If the mainspring is not wound up sufficiently, the watch may lose or gain time. If you do not wear the watch on your wrist, wind the mainspring up sufficiently by turning the crown by hand every day at a fixed time.

CAUTION

Do not set the date between 10:00 p.m. and 1:00 a.m. (between 11:00 p.m. and 1:00 a.m. for Cal. 9825). If the date is set during this period of time, the date may not change when the next day comes, or this may cause damage.

Due to its gear train mechanism, for setting the time of the mechanics watch correctly, the hands should be set back once slightly and then set forward to the correct time.

How to set the time and date

This watch is equipped with the date display function. The date changes once every 24 hours at around 12:00 a.m. Therefore, if the a.m./p.m. is incorrectly set, the date will change around 12:00 p.m.

③ Pull out the crown to me first click. If the watch is equipped with the screw down crown, unscrew the crown before pulling it out.)

(2) The date can be set by turning the crown clockwise (12 o'clock direction). First turn the crown clockwise until the previous day's date from the desired date appears.

[Ex.] If you want to set the date to "6," set the date to "5" by turning the crown dockwise.

③ Pull out the crown to the second clock when the second hand is at the 12 o'clock position. (The second hand stops.) Turn the crown counterclockwise to rotate the hands clockwise until the desired date appears. When the date changes, the time is a.m. Further turn the crown to set the current time.

④ Push the crown back into the normal position in accordance with a time signal. The watch starts operating.

CAUTION For modes with a screw down order, remember to screw the crown in.

Date adjustment at the end of the month

It is necessary to adjust the date after February (which has 28 days, 29 days in a loop year) and a 30 day month.

[Ex.]

To adjust the date in the a.m. period on the first day of a month following a 30-day month

On the first day, "31" is displayed. Pull out the crown to the first click. Turn the crown clockwise to set the date to "1", and push the crown back in to the normal position.

CAUTION For models with a screw down crown, remember to screw the crown in.

HOW TO USE (FOR CAL. 9S86, 9S66)

○ The mshaping can be sufficiently wound automatically by natural movement of the arm, while animals were on the walls. In andling it can be wound by turning the crown.
A stopped wissic can be started by arm movement when it was won't a wrist, however, before stopping the wissic, wind and the spring sufficiently and time and date. When wissing the spring, turn the crown at the normal position clockwise (12 o'clock direction) slowly, if you turn the crown count or six times (6 o'clock direction), it will turn free. The spring is sufficiently wound when the crown is turned approximately 45 times (50 times for Cal. 9860). When the spring is in the full-winding state, it is designed so that the spring slots if it is overswound. Therefore, it is not necessary to worry about breaking the mainspring, however, please return from excessive operation.

※ 1. It is recommended that you wear the watch on your wrist more than 10 hours a day to keep the mainspring wound up. If the mainspring is not wound up sufficiently, the watch may lose or gain time. If you do not wear the watch on your wrist, wind the mainspring up sufficiently by turning the crown by hand every day at a fixed time.

How to set the time and date

To set the time and date, set the 24 hour hand and minute hand first, and then set the hour hand and date.
When setting the time, make sure that the mainspring is sufficiently wound.

How to use the 24-hour hand

This watch has two different types of 24-hour hand usage.

24 hour "end as an a.m./p.m. indicator

Simply using the 24-hour hand to show the 24-hour time as an a.m./p.m. indicator. (This is the standard usage type for the 24-hour hand.)

Both the hour hand and the 24 hour hand are indicating the Japan time 10:00 a.m.

24-hour hand as a dual line indicator. Using the time difference adjustment function, set the 24-hour hand to indicate a time different from the time that the hour and minute hand indicate, which is of a place in a different time zone area with at least one hour of time difference from where you are.

Hour hard: Japan time 10:00 a.m.

24-hour hand: New York time 8:00 p.m.

Time difference adjustment function

For example, while traveling abroad and staying in a plane with a different time from where you live, you can conveniently set the watch to indicate the local time in the different time zone area without shopping for watch.

The hour hand indicates the time of the place where you currently are, while the 24-hour hand indicates the time of the place of origin.

The date works in conjunction with the movement of the hour hand. If the time difference is correctly adjusted, the watch displays the correct date of the place where you are staying.

How to use the time difference adjustment function

① Make sure that the mainspring is sufficiently wound and the watch is working.

* When selling the hour hand to use the time difference adjustment function, ensure that the watch is working.

② Unlock the crown.

→ "Scre down down" page 17.

③ Pull out the crown to the first click.

④ Turn the crown to set the hour hand to indicate the time of the place where you are staying. Make sure that a.m./p.m. and date are correctly set.

※ The date is designed to work in conjunction with the movement of the hour hand, therefore, incorrect setting of a m.p.m. will cause the date to change at room.

→ "I list of time zones differences in major regions of the world" page 26.

Turning the door CLDN Cuts is towards. The hour hand is advanced on foot. Turning the door counter, double (crown) hands. The hour hand is set back one hour.

The crown can be turned in either direction to set the time, however, it is recommended to turn the crown in the direction which enables you to set the date with a smaller adjustment.

※ Turn the crown slowly, choosing that the four hand moves in one-hour increments. ※ While turning the crown, the moment the case changes is midnight.

※ When setting the hour hand, the other hands may move slightly. However, this is not a malfunction.

⑤ Upon completion of setting, make sure that the time indicated is correct, and then push the crown back in. The setting procedure is now completed. Reck the crown. → "Screen down crown" page 17.

- if you set the time during any time between 8:00 p.m. and 1:00 a.m., temporarily set the hour hand back to 8:30 p.m., and then set the time.

Selectable display mode

With the time difference adjustment function, the watch features a dual time display which shows time in two different time zones. It offers two display modes which you can select to suit your needs and preference.

HOW TO USE (FOR CAL. 9S64)

How to wind the mainspring

○ This watch is a manual winding type.
○ In order to wind it up completely, please refer to the following table:

In case the watch is supposed to be wound up every day.	About 20 turns of the crown will wind up the watch fully.
In case the watch was not wound up more than three days.	About 50 turns of the crown will wind up the watch fully.

From the state of the mainsoring being sufficiently wound, it continuously operates for approximately 72 hours or more.
☐ If the manspring is not wound up sufficiently, the watch may lose or gain time. To attain a high accuracy we suggest that the manspring is wound up fully once a day at a fixed time.

Generally speaking, the crown of the manual winding mechanical watch cannot be turned further when it is wound up fully. However, the crown of CAL 9864 can be turned endlessly even after the watch is fully wound up. If you keep turning the crown, that gives no effect to winding, but the watch is so designed as to make the winding a little lighter and not to damage the watch. However, please refrain from excessive operation.

* When the watch is used from a state, in which the manspring is unwound to a stop, it does not move immediately even if the manspring is wound with his winding crown. This is because of the mechanical watch's feature that the manspring torque (force) is weak at the beginning, or mainspring winding. The second hand stems moving when the manspring is wound to much a certain degree of torque strength, while the watch can be made to move advance by sharing it to rotate the balance wheel forcibly.

Do not pull out the crown.

(if the watch is equipped with the screw down crown, unscrew the crown before pulling it out.)

Slowly turn the crown clockwise (12 o'clock direction) to wind the mainspring.

For models with a screw clean clean, remember to screen the crown in.

How to set the time

Pull out the crown when the second hand is at the 12 o'clock position. (The second hand stops.) Turn the crown to set the current time.

② Push the crown back in to the normal position in accordance with a fine signal. The watch starts opening.

HOW TO USE (FOR CAL. 9S61)

How to wind the mainspring

• This watch is an automatic winding type (with manual winding function).
• The mainspring can be sufficiently wound automatically by natural movement of the arm while normally worn on the wrist. In addition, it can be wound by turning the crown.
  A stopped watch can be started by arm movement when it is worn on the wrist, however, before wearing the watch, wind the mainspring sufficiently and set the time and date. When winding the mainspring, turn the crown at the normal position clockwise (12 o'clock direction) slowly. If you turn the crown counterclockwise (6 o'clock direction), it will turn free. The mainspring is sufficiently wound when the crown is turned approximately 50 times. When the mainspring is in the full-winding state, it is designed so that the mainspring slips if it is overwound. Therefore, it is not necessary to worry about breaking the mainspring, however, please retrain from excessive operation.

It is recommended that you wear the watch on your wrist more than 10 hours a day to keep the mainspring wound up. If the mainspring is not wound up sufficiently, the watch may lose or gain time. If you do not wear the watch on your wrist, wind the mainspring up sufficiently by turning the crown by hand every day at a fixed time.

CAUTION

☐ For models with a screw down crown, remember to screw the crown in.
Due to its gear train mechanism, for setting the time of the mechanical watch correctly, the hands should be set back once slightly and then set forward to the correct time.

How to set the time

① Pull out the crown when the second hand is at the 12 o'clock position. ( The second hand slope, ) I am the crown to set the current time.

② Push the crown back in to the normal position in accordance with a three signal. The watch seats operating.

HOW TO USE (For Cal. 9S64)

FUNCTIONS OF DIVER'S MODEL

Unidirectional rotating bezel

By using the rotating bezel, you can measure t elapsed time since the start of an event or an activity such as diving.

This watch has a unidirectional rotating bezel. As the evaluation of the remaining air in your cylinder is based on the information of the elapsed time of the dive, the rotating bezels for a cover's watch is designed to rotate only counter-clockwise, so that the watch is prevented from dislaying the elapsed time shorter than it actually

CAUTION

Make sure that you check the correct remaining amount of air in your cylinder before diving. Use the display of the elapsed time by the rotating bezel only as a guide during diving.

How to use the rotating bezel

① At the start of the activity, for which you want to measure the elapsed time (for example, when you start diving), rotate the bezel so that the mark on the bezel is aligned with the minute hand.
② Read the graduation on the rotating bezel to which the minute hand is coiling.

[Ex.] When you start diving at 10:10. Start of the dive

Align the ▼ mark with the minute hand has elapsed Rotating direction of the bell Read the graduation on the rotating bell to which the minute hand is pointing Elapsed time

Slide adjuster

If your watch has a metal bracelet equipped with a slide adjuster mechanism, you can easily adjust the bracelet length by yourself. This is very useful when you wear the watch over a wetsuit or a heavy winter clothing.

How to use the slide adjuster

Lift up the flap approximately 90° and press it down further approximately 20°, and hold it there.
※ You may feel slight resistance, but doing this requires only a light force. Please do not push the tan down forcibly.
② Lightly pull the bracelet on the 6 o'clock side of the watch along the curved line of the bracelet.
※ Again, doing this requires only a light force. Please do not put the bracelet forcibly. ※ The slider can be pulled out approximately 30 mm. Be careful not to pull it out beyond the limit mark inscribed on it.

Rap 1 2 Rapallet on the 6 c'clock side of your watch Bracelet on the 12 o'clock side of your watch

③ Holding down the push button, lift up the clasp to release the buckle, and strap the watch on your wrist.
④ Close the clasp first and then, the flap.
⑤ With the hand which is not wearing the watch, adjust the length of the slider so that the watch fills well around your wrist.

THE GRAND SEIKO STANDARD

Your Grand Seiko watch is built to the very highest standards to ensure that it keeps time as accurately as possible. In this section, we define the Grand Seiko Standard, what it means and how your watch is tested against it.

The "Grand Seiko Standard" is our own accuracy standard. Your watch has been tested individually and has met this standard. All Grand Seiko calibers are tested in the same way and for the same period but there are two standards, one for Grand Seiko men's watches and another for Caliber 9S25 which is used in Grand Seiko's women's watches. This is because the smaller size of Caliber 9S25 results in a different level of precision.

The movement in your Grand Seiko watch has been tested in our facilities for a period of 17 days, in six different positions and at three different temperatures. It has achieved or surpassed the standards of accuracy shown on page 75, with the accuracy being defined as a gain or loss per day (the "mean daily rate").

We specify "target values" for actual use and these are -1 second to +10 seconds for all callbers except 9S85 and 9S86 (-1 to +8) and -5 to +10 for 9S25. To judge the precision of your watch against these values, please measure the gain or loss over a week to ten days, and not just for one day, and in normal conditions. If the mean daily rate is outside these levels, we will adjust the watch free of charge within three years of purchase. After that period, such adjustments will be chargeable. Equally, the adjustment will be chargeable if the watch has been subject to any of the conditions below.

The watch has been used in ways that are not in line with the recommendations in this booklet, such as allowing it to be magnetized.
○ It has been opened or tampered with by anyone other than a Grand Selko repair center.
It has been damaged as a result of a natural disaster such as a flood, fire or earthquake.
○ Guaranteed conditions have been altered.

The Grand Seiko Special Standard

The Grand Seiko Special Standard is a precision standard even higher than the Grand Seiko Standard.
Watches that meet this standard are designated by the word "Special" printed on the dial.

Description of Grand Seiko Standard Terminology

Item Meaning
Position in inspection	Five orientations are specified by the International Standard ISO3159 so as to carry out various kinds of tests for time keeping. In addition there, in the CS inspection, 12 o'clock Up position in the state where a watch taken off the wrist is placed, is added, six orientations are specified (Dial Up, Dial Down, 12 o'clock Up, 3 o'clock Up, 6 o'clock Up, and 9 o'clock Up).
Mean daily rate	Mean value of a total of 12 daily rates measured in six different positions, respectively, for two days. This is a target value indicating basic gainloss per day of a watch, however, it is required to comprehensively judge the actual accuracy performance in consideration of other items.
Mean variation of daily rate	Mean value or a total of six variations of daily rates between the first day and second day when measured in six different positions for two days each. It indicates the degree which daily accuracy stabilizes in each position.
Maximum daily rate between two consecutive daily rates in the same position	Maximum value of a total of six variations of daily rates between the first day and second day when measured in six different positions for two days each. It indicates the degree which accuracy per day changes at maximum according to positions.
Variation of rate between positions horizontal and vertical	Indicates gain/loss in two positions at which a watch is most frequently used in daily life. It is a difference between mean daily rates for two days when a watch is placed in the dial Up position and mean daily rates for two days when a watch is placed in the 6 o'clock Up position.
Maximum daily rate between mean daily rate and any individual rate	Maximum difference value between daily rates for 12 days in the test initial stage and mean daily rates. It indicates the degree at which the daily rate varies according to the manner for placing a watch.
Variation of daily rate per 1°C between 8°C and 38°C	Variation in daily rates per 1°C between 38°C and 8°C in the same position (Dial Up position). It indicates gain/loss in the temperature environment taken-off state from the wrist where a watch is used.
Variation of daily rate per 1°C between 33°C and 38°C	Variation of daily rates per 1°C between 38°C and 29°C in the same position (Dial Up position). It indicates gain/loss in the temperature environment (won state of the wrist) where a watch is used.
Rate resumption	Value obtained by subtracting mean daily rates of initial two days from daily rate of the last inspection day. It indicates the degree at which daily rate stabilizes after usage for a predetermined period.

The Grand Seiko Standard Inspection Certificate

This certificate accompanies your watch. It shows the precision values achieved by the movement before the watch was ceased and that the movement met the Grand Selko Standard. The precision tests were conducted in an artificially controlled environment in our facility. The certificate shows the caliber number, the movement's individual number and the case's individual number.

It is important to note that, in actual use, the precision of all mechanical watches varies according to changes in ambient temperature, the position of the watch and the extent to which the mainspring is wound. As a result, the precision of your watch in actual use may show variations from the Grand Seiko Standard.

Your Grand Seiko Inspection Certificate is unique and cannot be replaced or reissued if lost or after maintenance or adjustment.

Cautions for accuracy of mechanical watch

Mechanical watches have a mechanism that is moved by power generated when the mainspring is unwound, and small metal parts physically work together to control the accuracy. Fragile metal parts of a mechanics watch are easily influenced by external environment such as temperature, gravity, and shock. Also, conditions of use such as normal usage lime and winding state of the mainspring can, influence the gain/loss of the watch.

① Accuracy of mechanical watch is "mean daily rate."

Accuracy of the quartz waton is indicated monthly or annually such as a monthly rate of ±15 seconds or annual rate of ±10 seconds. This indicates the degree of total difference in accuracy when the quartz watch is continuously used for a month or a year. To the contrary, accuracy of the mechanical watch is normally indicated as a "mean daily rate." Accuracy of the mechanical watch slightly varies each day as it is influenced by various conditions of use, and it is normally unstake. Then it is required to judge whether the accuracy is satisfactory or not by checking the mean value in the case of use for a week to ten days, but not only one time point. The average duration of Grand Seiko mechanical watch is 1 to 10 seconds (±8 seconds for Cal. 9S86 and 9S87s, as to 1 to 10 seconds for Cal. 9S23) per day are specified as target values. If the mean value exceeds the abandonment target value in the normal usage condition when the watch is used for a week to ten days, we will adjust it.

* Adjustment is provided time of charge within three years after purchase. After the three-year period, adjustments are charged. However, please note that the parts that are age-deteriorated due to long duration of use may not be adjusted to your desired accuracy. For details, refer to pages 32 and 37.

② Factor influencing accuracy -1: Wound amount of the mainspring In order to use the mechanical watch at better secureties, it is required to supply a constant strong energy whenever possible to respective parts. In the state where the mainspring is fully wound, accuracy is stable, however, when the mainspring is unwound to weaken energy to be supplied, the parts controlling accuracy tends to be externally influenced, and accuracy becomes unstable. In order to use a mechanical watch at a steady accuracy, it is recommended to use it in a condition where the mainspring is sufficiently wound.

③ Factor influencing accuracy -2: Temperature influence

Mechanical watch parts are metal which slightly elongate and contract by change in temperature, and this influences accuracy. Normally, under high temperatures, it tends to lose time, and under low temperatures, it tends to gain time.

④ Factor influencing accuracy -3: Difference by position (orientation of a watch) Paris related to accuracy of a mechanical watch are also influenced by the earth's gravity. For example, gain or loss differs when a watch is horizontally placed and when it is vertically placed in the 12 o'clock up position. When the watch is not worn on the wrist, accuracy errors that occur while wearing can also be compensated to some extent according to the position. Try to place it in various positions to find the position appropriate to your watch.

Daily care

The watch requires good daily care

Do not wash the watch when its crown is at the extended position.

○ Wipe away moisture, sweat or dirt with a soft cloth.

○ After soaking the watch in seawater, be sure to wash the watch in clean pure water and wipe it dry carefully.

※ If your watch is rated as "non water resistant" or "water resistant for daily use", do not wash the watch.

"CHECK THE CALIBER NUMBER AND WATER-RESISTANT LEVEL" page 10.

Turn the crown from time to time

○ In order to prevent corrosion of the crown, turn the crown from time to time.

○ The same practice should be applied to a screw down crown. ⇒ "Crown" page 17.

Band

The band touches the skin directly and becomes dirty from sweat or dust. Therefore, lack of care may accelerate deterioration of the band or cause skin irritation or stain on the sleeve edge. The watch requires a lot of attention for long usage.

Metallic band

○ Moisture, sweat or salt will cause rust even on a stainless steel band if they are left for a long time.

☐ Lack of care may cause a yellowish or gold stain on the lower sleeve edge of shirts.

○ Wipe off moisture, sweet or cool with a soft cloth as soon as possible.

To clean the soil around the joint gaos of the band, wipe it cut in water and then brush it off with a soft toothbrush (Protect the watch body from water splashes by wrapping it up in plastic wrap etc.).

Because some titanium bracelets use pins made of stainless steel, which has outstanding strength, rust may form in the stainless steel parts.

☐ If rust advances, pins may poke out or drop out, and the watch case may fall off the bracelet, or the class may not open.

○ If a pin is poking out, personal injury may result. In such a case, refrain from using the watch and request repair.

Leather band

○ A leather band is susceptible to discoloration and deterioration from moisture, sweat and direct sunlight

☐ Wipe oil moisture and sweat as soon as possible by gently blotting them up with a dry cloth.

○ Do not expose the watch to direct sunlight for a long time.

Please take care when wearing a watch with light-colored band, as dirt is likely to show up.

☐ Refrain from wearing a leather band watch other than Aqua Free bands while bathing, swimming, and when working with water even if the watch itself is water-resistant enforced for daily use.

Silicone band

As for material characteristics, the band is easily dirted, and may be stained and discolored. Wipe off dirt with a wet cloth or cleaning tissue. Unlike bands of other materials, cracks may result in the band being cut. Take care not to damage the band with an edged tool.

Notes on skin irritation and allergy

Skin irritation caused by a band has various reasons such as allergy to metals or leathers, or skin reactions against friction on dust or the band itself.

Notes on the length of the band

Adjust the band to allow a little clearance with your wrist to ensure proper airflow. When wearing the watch, leave enough room to insert a finger between the band and your wrist.

If the watch becomes magnetized and its accuracy deteriorates to an extent exceeding the specified rate under normal use, the watch may need to be demagnetized. In this case, you will be charged for demagnetization and accuracy readjustment even if it happens within the guarantee period.

The reason why watch is affected by magnetism.

The built-in balance spring is provided with a magnet, which may be influenced by a strong external magnetic field.

Lumibrite

If your watch has Lumibrite

Lumibrite is a luminous paint that is completely harmless to human beings and the natural environment; containing no noxious materials such as radioactive substance. Lumibrite is a newly-developed luminous paint that absorbs light energy of the sunlight and lighting apparatus in a short time and stores it to emit light in the dark. For example, if exposed to a light of more than 500 lx for approximately 10 minutes. Lumibrite can emit light for 3 to 5 hours.

Please note, however, Lumbrillo emits the light it stores, the luminance level of the light decreases gradually over time. The duration of the emitted light may also differ slightly depending on such factors as the brightness of the place where the watch is exposed to light and the distance from the light source to the watch.

※ In general, when you enter a dark place from a bright environment, your eye cannot adapt to the change in light levels quickly. At first, you can hardly see anything, but as time passes, your vision gradually improves. (Dark adaptation of the human eye)
