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 watches specifically designed for diving.

CAUTION

Do not pour running water directly from faucet.
The water pressure of tap water from faucitis high enough to degrade the water resistant performance of a water resistant watch for everyday life.

Mechanical watch characteristics (Hand-wound, auto-wound)

• This is amechanical watch powered by a spring.

• To use it from a stopped state, turn the crown 20 turns by hand to wind up the spring before starting the
  watch.

• Although the accuracy of quartz watches is measured indifferences over months or years, unmechanical watches it is measured in differences per day (i.e., the amount the watch speeds up or slows downing single day).

• Additionally, mechanical watches are subtly affected by the conditions in which they are used (e.g., duration worn, temperature, arm movement, the amount wound, etc.) ; thus, the amount of error is not
  constant.

• When affected by astrong magnetism rom outside, the mechanical watch may lose/gain time. The parts of the watch may become magnetized depending on the extent of the effect. In such a case, consult the retailer from whom the watch was purchased since the watch requires repair including demagnetizing.

Crown

There are two types of crowns, a normal crown and a screw down crown. 2 3 Please check the type of the crown of your watch.

• By locking the crown by screw, a screw down crown can prevent malfunction and increase water resistance. And Dat
• Be careful not to screw the crown in by force as it may damage the slots of the crown.

Screw lock type button

The screw lock type button features a mechanism that can securely lock the button when it is not being operated in order to prevent any operational errors.

• It is necessary to unlock the screw lock type button before operating it.
• Once you have finished operating the button, make sure to relock it.

[To unlock the button]

• Turn the button ring counterclockwise until it stops.
• • Now the button can be operated.

[To lock the button]

• Turn the button ring clockwise until it stops.
• Now the button can no longer be operated.

• If the screw or button get dirty, they may not operate properly. “Daly care”— P23
• Note that you turn the button fling more than you need to, the screw lock button may be difficult to fretum to its original position
• Do not use the buttons when the watch is wet or when you are underwater

How to wind the mainspring

• This is an automatic mechanical watch with a manual winding mechanism.
• When the watch is worn on the wrist, the mainspring is wound automatically through normal writs
• Tostart the watch after it stops completely, wind it up either by turning the crown or swinging it from side « Tum the button ring counterclockwise until it Bunion locked topside until the small seconds hand starts moving. Then, set the time and date before putting the watch stops. £37 (cannot be pressed) on the waist. To wind up the watch, turn the crown clockwise slowly. The watch cannot be wound by * Now the button can be operated. : turning the crown counterclockwise. In this way, the watch can be wound up fully. Furthermore, turning [To lock the button] ./ Button unlocked the crown further will not break the spring.
• For the watch with screw down crown, please inlock the crown before operating it and be sure to lock the crown Now the button can no longer be operated. after operating it
• Once the watch is wound up fully, it operates for about 45 hours.
• While the chronograph s used to measure a long period of time, however, the watch will stop operating before 45 hours
• If the watch is used without being wound up fully, gain or loss of time may result. To avoid this, wear the watch for more than 10 hours a day. If the watches used without being worn on the wrist, be sure to wind it up fully every day at fixed time.
• If you use a watch that has stopped with the mainspring unwound, winding the mainspring with the crown will not start the watch immediately. That is because the mainspring torque or force is low at the beginning of its winding due to the characteristics of mechanical watches. The small seconds hand will start to move when a certain degree of torque is reached after the mainspring has been wound up. However, swinging the watch from side to side to forcibly turn the balance can start the watch sooner.

Pull out the crown to the first click.
For models with screw down crown, please unlock the crown before operating it.

Pull out the crown to the first click

The date can be set by turning the crown.
Turn it until the previous day’s date appears. Ex.) To display the date as “6,” then set this to “5.” Turn the crown counterclockwise to set the date.

Pull out the crown to the second click and set the time
Pull out the crown to the second click when the small seconds hand is at the 12 o’clock position; the small seconds hand stops on the spot. Turn the crown to advance the hands until the date changes to the next. The time is now set for the A.M. period. Advance the hands to set the correct time.

Push the crown back in to the normal position in accordance with a time signal.
The small seconds hand will start moving. The telephone time signal service is helpful for setting the small seconds hand exactly. For models with screw down crown, please be sure to lock the crown after operating it.

How to set the time and date

The watch is provided with a date function and is so designed that the date changes once every 24 hours. The date changes around 12 o’clock midnight.
If AM/PM is not properly set, the date will change at 12 o’clock noon.

CAUTION
Do not amend the date when the watch is displaying between 8 PM and 2 AM. Amending the date during this time period may cause problems such as the date failing to change the next day.

CAUTION
The mechanism of mechanical watches is different from that of quartz watches. ‘When setting the time, be sure to turn back the minute hand a little behind the desired time and then advance it to the exact time.

Date adjustment at the end of the month

It is necessary to adjust the date at the end of February and 30-day months.

Ex.) To adjust the date in the A.M. period on the first day of a month following a 30-day month The watch displays “31″ instead of “1.” Pull out the crown o the first click. Turn the crown counterclockwise to set the date to “1” and then push the crown back in to the normal position.

3. Stopwatch hour hand (Measures up to 12 hours) (8R48 only)
4. Button A Start/Stop
5. Button B Reset of the stopwatch
6. Tachymeter → P.21
   The position of the tachymeter display may differ depending on the design of the model.

• Accumulated elapsed time measurement Ex. Measuring the time for a soccer match
  

How to read the stopwatch minute hand

For 8R48, which can measure up to 12 hours, the stopwatch minute hand makes a full rotation every 30 minutes. The readout is determined by the correlation between the positions of the stopwatch minute hand and the stopwatch hour hand. To read the minutes correctly, refer to the instructions below.

(Between 0 and 29 minutes)

(Between 30 and 59 minutes)

(Between 30 and 59 minutes)

While the stopwatch hour hand is pointing in some direction within the second half of an hour (after a short line of graduation and before a long line of graduation), add 30 minutes to the minute that the minute hand is pointing: in the case above, the measured time should be read as “6 hours 50 minutes 10 seconds”.

How to measure the hourly rate of operation

1. Measure the time (within 1 minute) required to complete 1 job.
2. Read the tachymeter scale where the center stopwatch seconds hand points.
   Ex. : If intakes 20 seconds to complete one product…180 products/hour
   

How to use the tachymeter

The numbers on the tachymeter scale can be read to determine how many seconds it takes to 1km or to measure the time required to complete 1 job.

How to measure kilometers / hour

1. Measure the time (within 1 minute) it takes to run 1 km.
2. Read the tachymeter scale where the center stopwatch seconds hand points.
   Ex. If intakes 45 seconds to run 1 80 Khmu
   

Daily care

The watch requires good daily care

• Do not wash the watch when its crown is in 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. Do not pour running water directly from a faucet onto the watch. Put some water into a bowl first, and then soak the watch in the water to wash it.
  • If your watch is rated as “Non-water resistant” or “water resistant for daily use, please do not wash the watch. “Performance and type”→ P.24 “Water resistant performance” → P.26

Turn the crown from time to time

• IN order to prevent corrosion of the crown, turn the crown from time to time.

Lambrate

If your watch has Lambrate

Lambrate is a luminous paint that absorbs the light energy of sunlight and lighting apparatuses ins 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 10minutes, Lifibrate can emit light for 3to 5 hours. Please note, however, that, as Lumibiite 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 coming from a place that is bright to a place that s dark, it takes human eyes some time to adapt to the darkness making difficult to see objects initially. (Dark adaptation) Lambrate is luminous paint that stores and emits light, which is harmless to human beings and the environment, containing no toxic materials such as radioactive substances.

Indication on the case back|| Condition of use
---|---
No indication| Keep the watch more than 5 cm away from magnetic products. (JIS level-1 standard)
| Keep the watch more than 1 cm away from magnetic products. (JIS level-2 standard)

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

The reason why a watch is affected by magnetism
The built-in balance spring may be influenced by a strong external magnetic field.

Examples of common magnetic products that may affect watches

• Note that the band may become discolored due to friction when wet with sweat or rain and that color may transfer to other clothing.
• Beware of static electricity caused by friction with clothing material.
• If natural skin o or dirt adheres to the band, gently wipe it off immediately with a dry cloth, etc.
• When drying the band, dry item an airy place out of direct sunlight.
• The texture of the band may change it is washed in water for a long time. + Note that the band may discolor liftin direct sunlight.

Band

The band touches the skin directly and becomes dirty with 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 soil will cause rust even on a stainless steel band f they are left for a long time.
• Lack of care may result in a rash or cause a yellowish or gold stain on the lower sleeve edge of shirts.
• Wipe off moisture, sweat or Soil with a soft cloth as soon as possible.
• To clean the soil around the joint gaps of the band, wipe it outing 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.) Clean it off with a soft cloth.
• Because some titan bands use pins made of stainless steel, which has outstanding strength, may forming the stainless steel parts.
• If rust advances, pins may poke out or drop out, and the watch case may fall off the band, or the clasp may not open.
• If alpines poking out, personal injury may result. In such abase, refrain from using the watch and request repair.

Silicone band

• As for material characteristics, the band is easily dirtied, 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.

After sales service

Notes on guarantee and repair

• Contact the retailer from whom the watch was purchased or SEIKO CUSTOMER SERVICE CENTER for repair or overhaul.
• Within the guarantee period, present the certificate of guarantee to receive repair services.
• Guarantee coverage is provided in the certificate of guarantee. Read carefully and retain it
• For repair services after the guarantee period has expired, if the functions of the watch can be restored by repair work, we will undertake repaid services upon request and payment.

Replacement with functional parts

• Please keep unmind that f original parts are not available, they may be replaced with substitutes whose outward appearance may differ from the originals.

Inspection and adjustment by disassembly and cleaning (Overhaul)

• Periodic inspection and adjustment by disassembly and cleaning (overhaul) is recommended approximately once every 2 to 3 years in order to maintain optimal performance of the watch for along time.
• The power transmission gear of the movement of this watch constantly receives force. To ensure that this mechanism works properly all the time, washing parts, changing oil, adjusting accuracy, checking functions and replacing consumable parts on a regular basis are important. The first overhaul after the purchase of your watch is particularly important for preserving long-time use of your watch. According tousle conditions, the oil retaining condition of your watch mechanical parts may deteriorate, abrasion of the parts due to contamination of oil may advance or delay the time significantly, or the watch itself may stop. As the parts such as gasket may deteriorate, water resistant performance may be impaired due to intrusion of perspiration and moisture. Inspection and adjustment by disassembly and cleaning (overhaul) should be performed by the retailer from whom the watch was purchased, and who specifies ‘SEIKO GENUINE PARTS.” At this time, also request replacement of the gasket and the spring bar.
• When your watch is inspected and adjusted by disassembly and cleaning (overhauled), the movement of your watch may be replaced.

Accuracy of mechanical watches

• The accuracy of mechanical watches is indicated by the “daily rate.”
• The accuracy of mechanical watches may not fall within the specified range of time accuracy because loss/gain changes according to the position of the watch, which is dependent on the conditions of use, such as the length of time during which the watch is worn on the wrist, arm movement, and whether the mainspring is wound up fully or not, etc.
• The loss/gain of mechanical watches is not measured by a daily rate, but by daily rates of one week or so.
• Accuracy variation according to temperature

The parts that compose the accuracy of mechanical watches are made of metals. It is well known that metals expand or contract depending on temperatures due to metal properties. This exerts an effect on the accuracy of the watches. Mechanical watches tend to lose time at high temperatures while they tend to gain time at low temperatures.

Mainspring wound condition and accuracy
In order to improve accuracy, it is important to regularly supply energy to the balance that controls the speed of the gears. The driving force of the mainspring that powers mechanical watches varies between when fully wound and immediately before it is unwound. As the mainspring unwinds, the force weakens. Relatively steady accuracy can be obtained by wearing the watch on the wrist frequently for the self-winding type and winding up the mainspring fully everyday at a fixed time to move it regularly for the wind-up mechanical type.

Effect of magnetism
When affected by a strong magnetism from outside, the mechanical watch may lose/gain time. The parts of the watch may become magnetized depending on the extent of the effect. In such a case, consult the retailer from whom the watch was purchased since the watch requires repair including demagnetizing.

Advance the hands by 12 hours.
Blur in the display persists.| A small amount of water has got inside the watch due to deterioration of the gasket, etc.| Consult the retailer from whom the watch was purchased.

For a solution to a problem other than listed above, contact the retailer from whom the watch was purchased.

Troubleshooting

Wind up the watch as per “How to wind the mainspring” → (P.11), and set the time. If the watch still does not operate, consult the retailer from whom the watch was purchased.
The watch gains/loses time.| The watch has been left in extremely high or low temperatures for a long time.| Return the watch to a normal temperature so that it works accurately as usual, and then reset the time. The watch has been adjusted so that it works accurately when it is worn on your wrist under a normal temperature rang between 5°C and 35°C.
The watch has been left close to an object with a strong magnetic field.| Accuracy cannot be recovered. Restoring the original accuracy requires demagnetization (repair). Consult the retailer from whom the watch was purchased.
You drop the watch, hit it against a hardsurface, or wear it while playing active sports. The watch is exposed to strong vibrations.| If accuracy does not return after setting the time, consult the retailer from whom the watch was purchased.
The watch has not been overhauled for more than 3 years.| Consult the retailer from whom the watch was purchased.
