■INTRODUCTION - Spring Drive watch -

Thank you for purchasing the Grand Seiko Spring Drive watch.

The Spring Drive is Seiko's unique mechanism in which the mainspring is wound by the natural motions of the user and accuracy is controlled by a microelectronics quartz mechanism while using the unwinding power of the mainspring to move the hands.

The Spring Drive powered by natural motions of the user can be called a watch that strongly combines and connects the user with the latest advancements in technology.

A mechanical watch of taste and refinement with an accuracy equivalent to a quartz watch, this sophisticated and innovative watch ticks in step with the pace of a person's life. This is a watch that creates a lifestyle for modern individuals who seek influence and convenience in their life. That is what the Grand Seiko Spring Drive watch is all about.

SEIKO WATCH CORPORATION

History of Spring Drive

Decades-long dream lives in the Grand Seiko

Grand Seiko's history symbolizes the culmination of efforts and development aiming for better practical watches. The Grand Seiko watch was born in 1960, reached the very top in the mechanical watch field around the world at the end of the 1960's. After a hiatus of dozen years or so, in 1993, the Grand Seiko 9F series equipped with world-class quartz movement was released. In 1998, the 9S series mechanical movement that combined traditional craftsmanship and advanced technology was developed to reintroduce the Grand Seiko mechanical caliber. While using the unwinding power of the mainspring as its sole power source, the new mechanism Spring Drive realizes an average monthly rate of ±15 seconds (For Cal. 9R96 9R16 and 9R15, ±10 seconds), substantially exceeding the accuracy of conventional mechanical watches. The watch also embodies the concepts of Grand Seiko that continues the challenge of creating the best practical watch.

Spring Drive Mechanism ① Spring Dr

Taste of a Mechanical Watch

[Non-Text]

High accuracy equivalent to a Quartz Watch

That is the concept of the Spring Drive.

Let's start from the drive method of a watch.

The method for driving a watch is divided into two types.

They are mechanical type and quartz type.

In a mechanical watch, the mainspring is wound and its unwinding

power moves the hands.

Amazing mechanism created by high quality workmanship,

and admiration goes to skilled craftsmen with passion.

You can feel the appreciation and personal touch of the craftsmen in

the ticking sound.

On the other hand, with quartz watches, the quartz is oscillated by a

battery and the hands are turned by a motor.

It is characterized by accuracy using state-of-the-art technology.

What is the Spring Drive like?

This is not a mechanical watch or a quartz watch.

In one word, this is a *mechanical watch having accuracy equivalent

to a quartz watch."

The Spring Drive is a self-contained drive system that realizes

accuracy equivalent to a quartz watch with only the power of the

mainspring and has no battery, motor, or secondary battery.

Accuracy of monthly rate of ±15 seconds (daily rate of ±1 second)

equivalent to a quartz watch is achieved while using a mainspring.

The Spring Drive is Seiko's proprietary mechanism which is made

available only by SEIKO's unique combination of skills in both

mechanical and electronic micro-engineering.

Then, how could it be possible to achieve such a degree of

accuracy?

That is explained on the next page.

※ For Cal. 9R96, 9R16 and 9R15, the average monthly rate is ±10

seconds

(equivalent to daily rate of ±0.5 second).

②

The power of the mainspring is regulated by electronic control. That is the essence of the Spring Drive.

What controls the accuracy of a mechanical watch is

the balance spring, a part of the speed-regulating unit, called the balance.

This part influences the accuracy to some extent

because it is made of metal which expands and contracts with charges in temperature.

The Spring Drive is

completely different from a mechanical watch in this speed-regulating unit.

The Spring Drive is powered by a mainspring.

but adopts an electronic speed-regulating unit comprising a generator, IC circuit, and crystal oscillator.

In a little more detail,

at the end of the train wheel that moves the hands, a series of speed increasing wheels with a glide wheel are provided.

The unwinding power of the mainspring rotates the glide wheel,

generating electricity in the coil to drive the crystal oscillator and IC.

The IC controls the spinning speed of the glide wheel by applying

and releasing the electromagnetic brake, while comparing the

accuracy of the electric signals generate

and the spinning speed of the glide wheel.

In addition, by making the energy transfer of the train wheel efficient

and adopting an IC that drives with low power consumption, power

reserve of more than 72 hours far exceeding normal mechanical

watches is realized.

An unprecedented drive system which offers quartz accuracy.

This is the Spring Drive.

Spring Drive Mechanism ③

Here is the step-by-step description of the Spring Drive in an easy-to-understand manner. This is how the Spring Drive works.

Mainspring

The mainspring is wound by rotation of the oscillating weight (or by turning of the crown), and its unwinding power is the sole power source.

Gear train • hands

The unwinding power of the mainspring is transmitted via the gear train to move the hands. No motor or battery is mounted.

Tri-synchro regulator

The unwinding power of the mainspring also rotates the glide wheel. This generates small electricity in the coil to drive the IC and crystal oscillator. At the same time, an electric magnetic field is generated on the glide wheel. The IC detects the spinning speed of the glide wheel based on the accuracy of the electric signals of the crystal oscillator, and adjusts the spinning speed of the glide wheel while applying and releasing the electromagnetic brake.

Oscillating Weight Mainspring Glide Wheel IC Crystal Oscillator Coll Tri-Synchro Regulator

Differences between the Spring Drive and mechanical watch

For the Spring Drive, the mainspring is wound and the unwinding power of the mainspring moves the hands in the same manner as the mechanical watch. It differs from the mechanical watch only in the speed-regulating unit (mechanism for controlling accuracy).

Temperature change

Accuracy of mechanical watches depends on a balance spring attached to a part called the balance. This part has properties for expanding and contracting with temperature changes, and influences the accuracy of a watch. Accuracy of the Spring Drive is never largely influenced by temperature changes like that of mechanical watches since the crystal oscillator controls it. (Note) Accuracy of the Spring Drive

Average monthly rate of +15 seconds (equivalent to daily rate of +1 second) is the accuracy of a watch when it is worn on a wrist at a temperature range between 5°C and 35°C.

* For Cal. 9R35, 9R16 and 9R15, the average monthly rate is ± 10 seconds (equivalent to daily rate of ±0.5 second).

Difference in position

For mechanical watches, the accuracy is influenced even by a difference in position or direction of a watch. This is also caused by the balance that controls the accuracy of mechanical watches. Due to the difference in position, the area where the shaft of the balance contacts with other parts differs, and such differences in resistance influence the accuracy. As the Spring Drive adopts a crystal oscillator not a balance, the accuracy is not influenced by a difference in position.

Impact

Mechanical watches are susceptible to impacts. If a mechanical watch was subject to impact, amplitude of vibration of the balance (angle for which the balance rotates right and left) is changed, and even the form of the balance spring is changed. In this regard, the Spring Drive is superior to mechanical watches in impact resistance because it adopts a crystal oscillator not a balance.

Overhaul

Parts that become worn or severely damaged are the balance, pallet fork, and escape wheel & pinion which are collectively called the speed-regulating unit or escapement. These parts come into contact or collide mutually and control unwinding of the mainspring. For the Spring Drive, wear and damage occur less than mechanical watches since the spinning speed of the glide wheel is adjusted by a "contact tree" (the motor) to be used in the car of a train is the same as mechanical watches, abrasion powder may be generated by contact of the wheels & pinions. An overhaul is recommended every three to four years.

■HANDLING CAUTIONS (applicable to all models)

■ 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 at 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 Seko 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.

If water-resistant level of your watch is defined as "DIVER'S WATCH 200m" or "AIR DIVER'S 200m"

WARNING

Never use the watch in saturation diving using helium gas.

While diving, never operate the watch in any other manner than described in this instruction manual.

When looking the crown, turn it slowly with care, ensuring that the screw is properly engaged. Be careful not to push it in forcefully, as doing so may damage the screw hole in the case.

Power reserve indicator

The power reserve indicator lets you know the winding state of the mainspring.

Before removing the watch from your wrist, observe the power reserve indicator to check if the watch has stored enough power to keep running until the next time you wear it. If necessary, wind the mainspring. (To prevent the watch from stopping, wind the mainspring to store the excess power that will allow the watch to run for extra time.)

Power reserve indicator

※ The continuous operating time of the watch may vary depending on the condition of use, such as the number of hours you wear the watch or the claim of your movement while wearing it.

※ In a case where you wear the watch for a short period of time, observe the power reserve indicator to check the level of the remaining power. If necessary, manually wind the mainspring.

To prevent the main spring from being overwound, the crown can no longer be wound forward once the spring is fully wound. Do not force the crown to turn any further at this point; doing so could damage the watch.

HOW TO USE (For Cal. 9R31)

How to wind the main spring

○ This watch has a manually wound spring drive.
You can wind the crown to wind the main spring to drive the watch.
Please see the power reserve indicator to check the level of the remaining power.
→ "How to read the power reserve indicator" page 19.
To wind 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. Seven full rotations of the crown will provide the power to run the watch for approximately ten hours.
When starting to use a watch after it has stopped, wind the mainspring sufficiently (so it is fully wound).
※ Under a low-temperature condition (below 0°C), always keep at least one-sixth of the watch power shown by the power reserve indicator.

How to set the time

① Pull out the crown to the first click when the seconds hand is at the 0 position. (The seconds hand stops.)
② Turn the crown counterclockwise (6 o'clock direction) to advance the hands to set the current time.
③ Push the crown back in to the normal position in accordance with a time signal. The watch starts operating.

Tips for more accurate time setting

To ensure effective operation of the Spring Drive mechanism, observe the following instructions when you set the time.

① Before setting the time, make sure to wind the mainspring sufficiently. (Ensure that the power reserve indicator is showing a full wound state.)
② When starting to use a watch after it stops, wind the mainspring sufficiently. To set the time after that, wait for approximately 30 seconds after the seconds band starts moving, then pull the crown out to the first click.
③ The seconds hand will stop moving when the crown is pulled out to the first click. Do not stop the movement of the seconds hand for longer than 30 minutes. If the stoppage of the seconds hand movement exceeds 30 minutes, push the crown back in, and wait for approximately 30 seconds after the seconds hand restarts moving, and then set the time.

HOW TO USE (For Cal. 9R84, 9R15, 9R65)

For the instructions on how to use the chronograph (stopwatch function) of Cal. 9R84, refer to "Chronograph (For Cal. 9R96, 9R86, 9R84)" on page 24.

How to wind the main spring

○ 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 it is worn on the wrist. In addition, the mainspring can be wound by turning the crown. Please see the power reserve indicator to check the level of the remaining power. ⇒ "How to read the power reserve indicator", page 18
When starting to use a stopped watch, it is recommended that you turn the crown to wind the mainspring. To wind 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. Five full rotations of the crown will provide the power to run the watch for approximately ten hours.
○ If you wear the watch for twelve hours per day consecutively for three to five days, the watch will be fully wound.
※ Under a low-temperature condition (below 0°C), always keep at least one-sixth of the watch power shown by the power reserve indicator.

CAUTIONS

Do not adjust the date when the time the watch indicates is between 9 p.m. and 1 a.m. If the date is adjusted in this condition, the date may not change properly the following day, or a malfunction may occur.
If you set the date when the time the watch indicates is between 9:00 p.m. and 1:00 a.m., pull out the crown to the second click, and turn it counterclockwise (6 o'clock direction) to advance the hour hand until it passes 1:00 a.m. temporarily, and then set the date.

How to set the time and date

This watch is equipped with the date display function. The date advances one day once every 24 hours around midnight. Therefore, if AM/PM is incorrectly set, the date will change around noon. When setting the date and time, ensure that the watch is working.

① Pull out the crown to the first click. (If the watch is equipped with a screw-lock type crown, unscrew the crown before pulling it out.)

② The date can be adjusted by turning the crown counterclockwise (6 o'clock direction). First turn the crown 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.

③ Pull out the crown to the second click when the seconds hand (or the small seconds hand) is at the 0 position. The seconds hand (or the small seconds hand) stops. Turn the crown counterclockwise (6 o'clock direction) to advance the hands until the desired date appears. If the

date changes, it means that the watch is set in the morning. Turn the crown further until the watch is set to the current time.

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

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 leap year) and a 30-day month.

[Ex.] To adjust the date in the morning on the first day of a month following a 30-day month.

On the first day of a 30-day month, "31" is displayed. Pull out the crown to the list click. Turn the crown counterclockwise to set the date to "1," and push the crown back in to the normal position.

CAUTION

For models with a screw-lock type crown, remember to screw the crown in.

Tips for more accurate time setting

To ensure effective operation of the Spring Drive mechanism, observe the following instructions when you set the time.

① Before setting the time, make sure to wind the mainspring sufficiently. (Ensure that the power reserve indicator is showing a full-wound state.)
(2) When starting to use a watch after it stops, wind the mainspring sufficiently. To set the time after that, wait for approximately 30 seconds after the seconds hand (or the small seconds hand) starts moving, then pull the crown cut to the second click.
③ The seconds hand (or the small seconds hand) will stop moving when the crown is pulled out to the second click. Do not stop the movement of the seconds hand (or the small seconds hand) for longer than 30 minutes. If the stoppage of the seconds hand (or the small seconds hand) movement exceeds 30 minutes, push the crown back in, and wait for approximately 30 seconds after the seconds hand for the small seconds hand restarts moving, and then set the time.

CAUTION

For models with a screw-lock type crown, remember to screw the crown in.

How to wind the main spring

☐ This watch is an automatic winding type (with manual winding function).
☐ Themainspring can be sufficiently wound automatically by natural movement of the arm while it is worn on the wrist. In addition, the mainspring can be wound by turning the crown. Please see the power reserve indicator to check the level of the remaining power. → "How to read the power reserve indicator" page 18.
When starting to use a stopped watch, it is recommended that you turn the crown to wind the mainspring. To wind 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. Five full rotations of the crown will provide the power to run the watch for approximately ten hours.
☐ If you wear the watch for twelve hours per day consecutively for 3 to 5 days, the watch will be fully wound.
※ Under a low-temperature condition (below 0°C), always keep at least one-sixth of the watch power shown by the power reserve indicator.

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.

Tips for more accurate time setting

To ensure effective operation of the Spring Drive mechanism, observe the following instructions when you set the time.

① Before setting the time, make sure to wind the mainspring sufficiently. (Ensure that the power reserve indicator is showing a full-wound state.)
② When starting to use a watch after it stops, wind the mainspring sufficiently. To set the time after that, wait for approximately 30 seconds after the seconds hand (or the small seconds hand) starts moving, then pull the crown out to the second click.
The seconds hand (or the small seconds hand) will stop moving when the crown is pulled out to the second click. Do not stop the movement of the seconds hand (or the small seconds hand) for longer than 30 minutes. If the stoppage of the seconds hand (or the small seconds hand) movement exceeds 30 minutes, push the crown back in, and wait for approximately 30 seconds after the seconds hand (or the small seconds hand) restarts moving, and then set the time.
④ If you set the time when the time the watch indicates is between 9:00 p.m. and 1:00 a.m., set the hour hand back to 8:00 p.m. temporarily, and then set the time. (This procedure is required to ensure the proper engagement of the date driving wheels.)

How to use the 24-hour hand

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

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

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

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 hand: 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 place 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 stopping the 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 setting the hour hand to use the time difference adjustment function, ensure that the watch is working.
② Unlock the crown. → "Screw-lock type crown" 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 slaying. Make sure that AM/PM and date are correctly set. ⑤ The date is designed to work in conjunction with the movement of the hour hand, therefore, if AM/PM is incorrectly set, the date will be off by 12 hours.

Turning the crown clockwise (12 o clock direction) The hour hand is set back one hour.

Turning the crown coumerclockwise [5 o'clock direction] The hour hand is advanced at hour.

The crown can be turned in either direction to adjust the line, 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, checking that the hour hand moves in one-hour increments.

※ While turning the crown, the moment the date changes is midnight. ※ When adjusting 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. Relock the crown. → 'Screw-lock tree crown', page 17.

※ If you set the time when the time the watch indicates is between 9:00 p.m. and 1:00 a.m., set the hour hand back to 8:00 p.m. temporarily, 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.

[Ex. 1] [Ex. 2] Hour hand and date: Area A Hour hand and date: Area B (New York) (Japan) 24-hour hand: Area B (New York)

Set the 24-hour hand first, and then set the hour hand.

How to use the bi-directional rotating bezel

Some models may have a bi-directional rotating bezel, the rim of the glass. By utilizing the 24-hour indicators imprinted on the rotating bezel, the watch can independently display the time in one or two different time zones in addition to the time indicated by the hour hand.

[Ex.] To set the 24-hour hand to indicate the time in Paris and Bangkok which are located in two different time zones, while setting the hour hand to display 10:00 a.m., Japan time. *To use the 24-hour indicators on the rotating boxel to indicate the hour in Bangkok.

① First, set the "▽" mark on the rotating bezel to the 12 o'clock position.

⑨ Refer to "Time difference adjustment function" page 33, and set the hour and minute hands to 10:08 a.m. and align the 24-hour hand with "2" on the rotating bezel. Time in Paris is 8 hours behind Japan except for summer seasons when daylight saving time is observed.

③ There is a 6-hour time difference between Paris and Bangkok; the time in Bangkok is 6 hours ahead of the time in Paris (when daylight saving time is not in effect). Turn the rotating bezel counterclockwise to move the "7" mark back 6 hours on the 24-hour indicators. The hour in Paris is shown by the 24-hour hand pointing to "2" (2:00 a.m.) of the 24-hour indicators on the dial (or the outer frame of the dial), while the hour in Bangkok is shown by the 24-hour hand pointing to "8" (8:00 a.m.) of the 24-hour indicators on the rotating bezel.

■ FUNCTIONS OF DIVER'S MODEL

Unidirectional rotating bezel

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

This watch has a undirectional 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 diver's watch is designed to rotate only counterclockwise, so that the watch is prevented from displaying 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 pointing.

[Ex.] When you start diving at 10:10.

The reason why this watch is affected by magnetism

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

Lumibrite

If your watch has Lumibrite

Lumibrile is a luminous paint that is completely harmless to human beings and the natural environment; containing no noxious materials such as radioactive substance. Lumibrile 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 lux for approximately 10 minutes, Lumibrile can emit light for 3 to 5 hours.

Please note, however, Lumibrite 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)

Reference data on the luminance

	The watch has been left close to an object with a strong magnetic field.	Correct this condition by moving and scoping the watch away from the magnetic source, and reset the time. If this action does not correct the condition, contact the retailer from whom the watch was purchased.
	You drop the watch, hit against a hard surface, or wear it while playing active spots. The watch is exposed to strong vibrations.	Reset the time, if the watch does not return to its normal accuracy after resetting the time, contact the retailer from whom the watch was purchased.
The date changes during daytime.	The time is set 12 hours ahead or behind the correct time.	When you set the time move that the moment the date changes is midnight. When setting the hour hand, he sure that AM/PM is correctly set.
Even though you rest the watch every day, the power reserve indicator does not move up.	The watch is worn on your wrist only for a short period of time, or the amount of arm movement is small.	Wear the watch for an extended period of time. Or turn the crown to wind the mainspring.
Right after starting the watch, it seems that the seconds hand moves more quickly than usual when setting the time.	When the watch starts moving, it takes a little time before the speed regulating unit starts operating. (This is not a malfunction.)	It takes several seconds before the speed-regulating unit starts operating. To set the time correctly, wait for approximately 30 seconds after the seconds hand starts to move, and set the time.
Blur in the display persists.	Small amount of water has got inside the watch due to coloration of the gasket, etc.	Consult the retailer from whom the watch was purchased.

※ For the solution of troubles other than above, contact the retailer from whom the watch was purchased.

*1: The average rate is estimated in a condition when the watch is worn on your wrist within a temperature range between 5°C and 35°C.

*2 Under a low-temperature condition (below 0°C), always keep at least one-third of the watch power shown by the power reserve indicator.

- When the power search indicator shows the answer supplied by the engineering is full, the continuous operating time may become shorter during on the condition of use.
