Frequently Asked Questions


Please take your watch to our service center once every three years for examining, cleaning and oiling of parts where needed.

To improve the accuracy of a mechanical watch, it is recommended that you wind up the mainspring every day, at a fixed time, even if the watch is a self-winding type.

Wind up your watch before you wear it
It is important that sufficient energy is supplied to each movement by the mainspring of the watch. The accuracy of a mechanical watch will be more stable if it is wound up sufficiently. If the spring unwinds causing the energy level to drop, the parts controlling accuracy become easily affected by environmental factors.

Wind the mainspring up fully to stabilize accuracy
If the watch is used without being fully wound up, a gain or loss of time may result. To avoid this, it is recommended that you wear the watch daily for more than 8 hours.

Mechanical watches have a mechanism that is moved by power generated as the mainspring unwinds, and small metal parts that work together to control accuracy. The fragile metal parts of a mechanical watch are easily influenced by environmental factors such as temperature, gravity, and shock. Also, conditions of use such as regular usage time, movements of your arm and winding state of the mainspring can influence the gain / loss of the watch.

Temperature : Do not place the watch where the temperature is extremely low / high (less than 5ºC or more than 35ºC)
Mechanical watch parts are metal and slightly expand and contract with changes in temperature, and this influences accuracy. Normally, under high temperatures, a watch tends to lose time, and under low temperatures, it tends to gain time.

Magnetism : Keep the watch away from magnetic fields
Watches can be adversely affected by magnetism and may gain or lose time. It is important not to leave a watch close to magnetic objects for a long time. In particular, cell phones, television and PC speakers, magnetic necklaces, handbag clasps, hair-driers, electric razors, magnetic parts of refrigerators are all magnetic. An affected watch remains magnetically charged even after being removed from the magnetic source.

Shock : Strong shock may affect accuracy
It is recommended that you remove your watch before playing any sport that involves strong impacts. Any direct impact to your wrists can affect the very small parts inside the watch. Dropping the watch may also cause damage.

Position : The accuracy of the watch is affected by its position when it is not worn on the wrist.
The rates of loss / gain of mechanical watches vary slightly depending on positions they are put in, such as being placed horizontally with its face or back turned up, or being laid on its 12:00 / 3:00 / 6:00 / 9:00 side respectively. This is because gravity affects the operation of the inside movement of the watch. Experiment with storing the watch in various positions for 7 to 8 hours when not in use and check the loss / gain of each position. By storing the watch in a resting position that minimizes loss / gain you may counteract the loss/ gain which occurs while the watch is being worn.

The accuracy written on the Grand Seiko Standard Inspection Certificate is the accuracy of the Grand Seiko mechanical watch movement at rest, which is measured before the inside movement of the watch is assembled in the case. Since the accuracy of a mechanical watch varies slightly depending on individual user conditions, the actual accuracy during use may differ from the numerical value specified in the certificate. The accuracy is affected by conditions such as winding state of the mainspring due to movement of the users’ arm, ambient temperature, and posture (direction of the watch).

The target accuracy range of Grand Seiko mechanical watches in use is -1 to +10 seconds per day. To determine accuracy in use, measure loss / gain under normal use conditions for approximately 7 to 10 days and calculate the average loss / gain per day.

The accuracy of mechanical watches varies slightly from day to day, depending on various conditions. Therefore, the loss / gain of mechanical watches is not measured by a daily rate, but by an average daily rate over a period of 7 to 10 days. For this reason, the accuracy of mechanical watches is indicated by "the mean daily rate."

The accuracy of the mechnical watch in use

The accuracy of a mechanical watch varies slightly depending on individual user conditions such as winding state of the mainspring due to movement of the users’ arm, ambient temperature, and posture (direction of the watch). Accordingly, actual accuracy of a watch in use may differ from specifications in the "Grand Seiko Standard."

The target accuracy range of Grand Seiko mechanical watches in use is -1 to +10 seconds per day. To determine accuracy in use, measure loss / gain under normal use conditions for approximately 7 to 10 days and calculate the average loss / gain per day.

The accuracy of the mechanical watch movement at rest

To establish a benchmark accuracy of a mechanical watch which does not depend on usage environment, loss / gain of a mechanical watch is measured before the movement is assembled in the case. The accuracy of the movement is measured under controlled conditions over a certain number of days, and the result is called "the accuracy of a mechanical watch movement at rest."

The measurement result for each watch is written in the "Grand Seiko Standard Inspection Certificate," which is provided with the watch by the retailer at time of purchase. This result is an average loss / gain of time over a 17 day period, which was measured in the factory where the temperature and position of the movement are controlled in accordance with the "Grand Seiko Standard."

The accuracy of Grand Seiko differs according to the mechanism and caliber of your watch. For details on your watch, please refer to the instruction that came with your watch at the time of purchase.

Guidelines for the accuracy of Grand Seiko while in use:

QUARTZ : The annual accuracy is ±10 seconds when worn on the wrist within a normal temperature range (between 5 ºC and 35 ºC) for approximately 8 hours per day.

SPRING DRIVE : Average monthly loss / gain is ±15 seconds when worn on the wrist within a normal temperature range (between 5 ºC and 35 ºC).

MECHANICAL : Accuracy of Grand Seiko mechanical watches when worn is specified within the target range of -1 to +10 seconds per day. To properly judge the accuracy under normal use conditions, check the mean value of gain / loss over a period of seven to ten days.

For information on general factors that affect accuracy of mechanical watches, please refer to "Accuracy of mechanical watches."

Grand Seiko Standard

Accuracy of mechanical watches

The Grand Seiko Standard Inspection Certificate cannot be reissued.

The Grand Seiko Standard Inspection Certificate certifies that the measured values of a movement, which were measured in a scientifically controlled environment in the manufacturing plant, have passed the Grand Seiko Standard Inspection. The certificate is printed with the caliber number, movement serial number, and case serial number.

* Inspection of the movement for the Grand Seiko Standard Inspection Certificate is made prior to casing. Movement performance is carefully measured in the static position under scientifically controlled conditions.
* The accuracy of the watch may vary depending on the actual usage conditions and may differ from the certified accuracy.

For details, please refer to Grand Seiko’s Certificate and Inspection Process.

Grand Seiko Standard is a Seiko-exclusive accuracy standard for mechanical watches which has been established to ensure superior performance of Grand Seiko mechanical watches irrespective of the differences in environmental conditions in which a watch is used. "Grand Seiko Standard Inspection," which measures gain / loss (daily rate) under various environments, is carried out at the manufacturing plant for 17 days in total, and only mechanical watches that satisfy the standard are given the title of "Grand Seiko."

The Grand Seiko Standard differs from the other recognised chronometer standards in two important respects. While most accuracy standard testing is done for five positions at two temperatures, the Grand Seiko Standard tests six positions at three temperatures. This is because the Grand Seiko Standard seeks to replicate real world conditions. The sixth position, namely the 12 o’clock upright position, is the way many people place their watch when not wearing it. In addition, the extra temperature rating is closer to body temperature. The idea is simple - to test the watch under conditions similar to actual use.

* Inspection of the movement for the Grand Seiko Standard Inspection Certificate is made prior to casing. Movement performance is carefully measured in the static position under scientifically controlled conditions.
* The accuracy of the watch may vary depending on the actual usage conditions and may differ from the certified accuracy.

Resetting the system is not recommended. If you do reset the system, please go through the following procedures before usage, because the watch returns to the initial state after the system is reset.

After resetting the system (built-in IC):

  1. Make sure the watch is sufficiently charged until the indicator hand displays “F (full)” or in between "F" and "E (empty)."
  2. Adjust the preliminary position of the date and indicator hand. The hour / minute / second hand does not need to be adjusted, since the automatic hand position alignment function will activate.
  3. Adjust the hands of the sub-dial.
  4. Set to the correct time zone setting.
  5. Successfully receive the leap second data. (The leap second reception function activates when GPS signals are received after the system is reset. )

The preliminary position of the indicator hand may be misaligned and displaying charging status other than "E (low)" even though the charging status is actually low. Please adjust the premilinary position of the indicator to the correct position (the middle of “E” and "airplane mark") and check the charging status again. If the indicator hand displays "E," recharge the watch.

How do I adjust the preliminary position of the date, indicator hand, and hour / minute hands?

The preliminary position of the indicator hand may be misaligned. This occurs when the preliminary position of the indicator hand is misaligned due to external factors or system reset. Please adjust the premilinary position of the indicator to the correct position (the middle of “E” and "airplane mark").

How do I adjust the preliminary position of the date, indicator hand, and hour / minute hands?

The automatic leap second reception function has been activated. The indicator hand points to the right side of "4+" when GPS signals are received (time zone adjustment or time adjustment) around June or December. This indicates that the watch is ready for leap second data reception or receiving leap second data. At this time, the second hand points to any of the 0 to 18-second positions to indicate the waiting time in minutes until leap second data reception. The waiting time decreases each minute, and when the second hand points to the 0-second position, the leap second data reception begins. It is recommended you move to a place where it is easy to get a GPS signal reception.

* This function activates every time the watch receives GPS signals until it successfully receives leap second data.

The preliminary position may be misaligned due to a strong impact or magnetism. For detailed procedures, please refer to How do I adjust the preliminary position of the date, indicator hand, and hour / minute hands?

Please check the following:

  1. The last GPS signal reception result: The time adjustment / time zone adjustment may not have been successful. If reception was unsuccessful, please move to a place where it is easy to get a GPS signal reception or set the time zone manually.

  1. Push the crown back in, and wait for the second hand to start moving. It will start moving within 9 minutes.
  2. Start the operation again from the beginning.

This is a sign that the charging status of the watch is very low. The watch is unable to receive the GPS signals, and does not have sufficient energy to operate. Please recharge the watch until the second hand starts moving at 1-second intervals and the indicator hand points to “F (full)” or in between "F" and "E (empty)."

If the second hand starts moving at 2 or 5-second intervals even when the user wears the watch everyday, the watch may not be receiving sufficient light. For instance, the watch may be concealed under a long sleeve shirt and is not adequately exposed to light. In this case, try to place the watch in an environment where it will be exposed to light when not being worn.

How to prevent a solar watch from running out of energy

This indicates that the charging status of the watch is low. When the charging status is displayed as “E,” the watch is unable to receive the GPS signals even when the user performs manual GPS signal reception. Since GPS signal reception consumes a lot of energy, please remember to charge the watch on regular basis. To ensure optimal performance of the watch, it is advisable to have the indicator hand pointed to “F (full)” or in between "F" and "E (empty)" at all times.

Daylight Saving Time (DST) is individually set by the users depending on the area of residence. DST means "summer time," which is a system to lengthen daylight hours by advancing 1 hour when days are longer in summer. Currently, DST has been adopted in Europe and North America, and the adoption and duration vary depending on the country.

How to turn ON Daylight Saving Time:

  1. Press Button A (at 10 o’clock position) once and then release it. The indicator hand will move to indicate the current DST setting ("ON" or "OFF").
  2. Press Button C (at 4 o’clock position) for 3 seconds within 5 seconds after step 1.
  3. The indicator hand will move and point to “ON,” and the hour and minute hands will advance by one hour.
  4. The DST is turned ON when the hands stop moving, and the watch returns to the normal time display.

How to turn OFF Daylight Saving Time:

  1. Press Button A (at 10 o’clock position) once and then release it. The indicator hand will move to indicate the current DST setting ("ON" or "OFF").
  2. Press Button C (at 4 o’clock position) for 3 seconds within 5 seconds of step 1.
  3. The indicator hand will move and point to “OFF,” and the hour and minute hands will turn back one hour.
  4. The DST is turned OFF when the hands stop moving, and the watch returns to the normal time display.

In order to avoid any interference with the operation of electronic devices in an airplane, please set the watch to the in-flight mode when boarding a plane. In the in-flight mode, the GPS signal reception function (time zone adjustment, manual time adjustment, and automatic time adjustment) will not work.

How to set ASTRON to the in-flight mode:

  1. Press Button B (at 2 o’clock position) and release it.
  2. Within approximately 5 seconds after pressing Button B, press Button C (at 4 o’clock position) for 3 seconds. The second hand will stop at the 40-second position, and the indicator hand will point to the"airplane mark."
  3. The watch is now set to the In-flight mode, and it will return to the normal time display after 5 seconds.

The dual time displayed by a sub-dial also keeps accurate time by using GPS signal reception. When the watch receives GPS signals, the time of the sub-dial is also adjusted.

However, since the sub-dial is designed to display the home time of the user, it will not adjust to local time even when the user performs time zone adjustment. The sub-dial will keep the precise home time unless the user changes it manually.

Respective times of two regions can be displayed by the dial and sub-dial.
Example: Honolulu time and Japan time are respectively displayed by the dial and sub-dial.

The watch can identify the time zone of its present location and adjust to local time by manually receiving the GPS signals. This adjustment can be made by performing a button operation.

Please note that the time of the sub-dial will not change along with the time of the dial, because the sub-dial moves independently of the dial. The sub-dial will display the precise home time (the time before performing time zone adjustment), unless the user changes it manually.

How to perform time zone adjustment:

  1. Make sure you are in a place where it is easy to get GPS signal reception.
  2. Press Button B (at 2 o’clock position) for 6 seconds, and then release it when the second hand moves to the 30-second position.
  3. Hold the watch with the face upward and wait for the watch to complete reception. During reception, the second hand will move and stop at several positions.
  4. The reception is completed successfully when the second hand points to "Y" (at 12-second position).
  5. If the second hand points to "N" (at 18-second position), please try again outdoors under an open sky.

In locations where GPS signals cannot be received, the time zone can be changed manually by button operation. Please refer to pg. 20 "Manual time zone setting" in the instruction manual for the details of the procedure.

7X52 (GPS Solar) Complete User Guide

When the watch is in an environment where it is unable to receive GPS signals for an extended period, you can adjust to the precise current time by receiving the signal manually. By performing a manual time adjustment, the watch will display the precise time of the currently set time zone. Please note that successfully receiving the the GPS signal depends on the reception environment.

How to perform manual time adjustment:

1. Make sure you are in a place where it is easy to get GPS signal reception.

2. Press Button B (at 2 o’clock position) for 3 seconds, and then release it when the second hand moves to the 0-second position.

3. Hold the watch with the face upward and wait for the watch to complete reception.

4. The reception is competed successfully when the second hand points to "Y" (at 12-second position). Please note, the reception may take maximum time of one minute.

5. If the second hand points to "N" (at 18-second position), please try again outdoors under an open sky.

Yes, ASTRON is equipped with "automatic time adjustment" function. The watch will automatically receive GPS signals and set itself to the precise current time of the currently set time zone once a day. The automatic time adjustment is performed when the watch is exposed to bright light outdoors under an open sky where GPS signals reception is good. For this time adjustment to take place however, it is essential for the watch to have sufficient charge. If the energy stored in the watch is insufficient, the automatic time adjustment function may be activated once in 3 days.

Please note that the automatic time adjustment will not be performed when the watch is concealed under a sleeve and the dial is not exposed to sufficient light, even outdoors under an open sky. In this case, the watch records the time of the previous successful manual time adjustment (or time zone adjustment), and automatically starts time adjustment at the recorded time.

GPS signals can be easily received under the open sky with good visibility. The less exposure to the sky, the more difficult it is to receive GPS signals. In addition, reception will also be difficult in places where there are objects or buildings that obstruct the GPS signals, particularly during "time zone adjustment". Furthermore, alignment of satellites, weather conditions or the sun’s turbulence can affect reception condition temporarily. Examples of places and conditions as are follows:

Easy to get reception:

- Outdoors under an open sky with good visibility

Difficult to get reception:

- Between tall buildings

- Near wooded areas

- At Stations / Airports

- Indoors with windows

No reception:

- Indoors without windows

- Underground

- While passing through tunnels

- Through special glass with thermal emission shield effect, etc.

- Close to equipment that is generating noise or performing wireless communications

Please check whether the reception result of the last GPS signal reception was successful or not.

GPS signal reception consumes a lot of energy. Remember to recharge the watch by exposing it to light so that the indicator hand points to the "level position (middle)" or "F (full)."

We recommend that you contact an Authorized Seiko Service Center or a Seiko appointed dealer to have your watch strap adjusted. If it is not convenenient to visit a service center or a dealer, please consult staff at the store where the watch was purchased.

If you have an old watch to repair, please contact an Authorized Seiko Service Center or a Seiko appointed dealer.

However, for repair of old watches, there may be a depletion of the parts in stock, and sometimes a watch cannot be repaired due to the discontinuation of necessary parts. Should that be the case, we regret we will have to return your watch unrepaired. Nevertheless, be assured that we will do our utmost to return your watch to its best working order.

As with eye-glass frames or accessories, skin irritation may result from metal ions from the metal parts of a watch being extracted by perspiration. This kind of reaction is categorized as allergic skin dermatitis, which is caused by metals such as nickel, cobalt or chrome. These metals are included not only in metal bands but also in leather straps (chrome is used for tanning).

If you experience allergic reaction, stop wearing the watch immediately and consult a dermatologist. With a doctor’s assistance, clarify which metal caused the allergic reaction, and try to avoid selecting products which contain this metal. For those who are allergic to nickel or hyper-sensitive to stainless steel, we recommend that you use a titanium watch. For information on Seiko products made of titanium, please contact an Authorized Seiko Service Center. 

Seiko watches are designed to provide accurate and reliable service over a long period. However, like any sensitive precision instrument, a watch needs periodic servicing to ensure that it functions perfectly. Frequency of such work depends on the climate and the owner’s individual care of the watch, but in general, we recommend having your watch serviced about every three years at an Authorized Seiko Service Center.

 

Worn out movement parts and aged oil inside the movement may cause a watch to lose time or stop. Therefore, our technical specialists will inspect the watch for any worn out parts that need repair or replacement, and the disassembled parts will be cleaned and oiled again. Furthermore, a watch’s water resistance is not permanently guaranteed. It is affected by the ageing of gaskets or deformation of watch parts due to an accidental shock. Since deterioration of gaskets can cause rust or moisture inside the movement, we recommend that you have the water resistance of the watch checked regularly to ensure it’s functionality.

A mechanical watch, which is run by a spring is easily influenced by the environment or the conditions in which it is used. This affects the acuracy of mechanical watches. 

The accuracy of the mechanical watch varies slightly each day as it is influenced by various conditions of use, and is therefore unstable. It varies depending on several factors such as the amount the spring is wound, movements of your arm, temperature, and the position of the watch.

However, we will also accept a proof purchase from an authorised retail outlet to perform under guarantee repairs.

Shocks: Your watch is a precision measuring instrument. Treat it carefully, and it will serve you well. Avoid undue shocks (such as dropping on hard surfaces). The normal shocks caused by sports like tennis or golf present no threat, but "Twin Seiko" (extra-high precision) watches should not be worn while participating in such sports.

Perspiration: You should aim to protect your watch from heavy perspiration. Please remember to wipe it dry as soon as conveniently possible.

Temperature Extremes: Quartz watches are much less affected by extremes of temperature than mechanical watches, and are designed to keep good time if worn on the wrist for eight hours a day with ambient temperatures between -10°C and +35°C. If removed completely from the wrist, your watch may lose time during the winter, but will return to normal accuracy as soon as you start wearing it again.

If your watch is stored at temperatures outside the normal range (as low as -10°C or as high as +60°C) the electronic components may cease to function normally.

The response time of liquid crystals used in the displays on digital watches at temperatures below freezing is slow, and they tend to look very dark at high temperatures, but normal performance returns at normal temperatures.

Battery life can be significantly reduced at high temperatures (above 40°C), and battery fluid may even leak out.

Chemicals: Chemical substances, gases, mercury, etc., may change the color of cases, bracelets and straps. Mercury (for instance, from a broken thermometer) can cause particularly unsightly grey discoloration of gold plating.

SEIKO Australia provides a service network around Australia. Please call SEIKO Service on 1300 363 575 for the service agent in your state. If you are taking or sending your timepiece to a service centre/agent please:
a.) Include a small note outlining the problem or symptoms you are having with the watch or clock.
b.) Include your original guarantee or proof of purchase if the timepiece is still within the warranty period.
c.) If mailing, please ensure that your name and address are shown both on the outside of the package as a return address and on the correspondence inside describing the problem. Also, keep a record of the case number (hyphenated) and the serial number from the back of your watch for reference.
d.) Always send the timepiece using registered mail to protect yourself in case of a loss in transit and to make tracing possible if necessary.
e.) Package the timepiece well in bubble wrap to protect it in transit.

SEIKO quartz watches are designed to provide a lifetime of accurate and reliable service. However, every three to five years, or when you replace the battery, it is recommended that you visit a SEIKO service agent to have your watch serviced. They will inspect your watch for any worn parts that may need replacement, check whether it needs lubrication, and whether perspiration or water, dust, etc., have entered the watch.

Please note that Kinetic and digital watches should also be regularly checked, for the effects of perspiration, dust, etc., and may need to be taken apart and cleaned.

Metal bracelets should be washed carefully in water. If really dirty, use a soft toothbrush with soap and water to brush away the dirt. Finally, rinse with water and dry carefully with a soft cloth. If your watch is not water resistant, be careful not to get water on the case. Cases should be wiped gently with a slightly moistened soft cloth and then dried carefully.

Leather straps should be slightly loosened in the summer, when they may absorb perspiration. A tight strap not only prevents the passage of air over the strap undersurface but can also cause a perspiration rash on the wrist.

If the strap ever becomes wet with perspiration, wipe it dry with a soft cloth.

When you take off your watch, leave it in a well-ventilated spot. Never put it in a sealed container when it is still damp with perspiration.

Avoid leaving your watch in direct sunlight. The strap color may fade.

If you request a quote, one will be given. If your timepiece is out of warranty, and the warranty details have been sent, you will receive a written estimate outlining all repair costs. You can reply to the estimate by returning the postcard or calling the appropriate service centre. If you give instructions in your letter that no estimate is necessary, no estimate will be given and the repair will be initiated.

Watch accuracy depends on the movement used in the watch, as to whether it is quartz battery or automatic mechanical operated. Please refer to the information in your instruction booklet. If the accuracy of your watch is outside the standard range, we recommend you contact the service network to have the accuracy adjusted.

A repair completed by a SEIKO service centre has a repair warranty of SEIKO (12) months; Pulsar (6) months and Lorus (6) months. This warranty covers the parts used and labour expended in the repair. It excludes any other faults that may occur, including accidental damage or use other than normal, fair wear and tear.

It doesn't usually affect digital quartz watches, but it can affect analogue watches, which use a tiny electric motor to turn the hands. Powerful magnetism can affect the performance of this motor.

The good news is that although analogue watches may gain time, lose time, or even stop under the influence of powerful magnetic fields, they will usually return to normal time-keeping as soon as they leave the source of magnetism. (You may need to reset your watch, of course.)

Avoid putting your watch near medical equipment, headphones, loudspeakers, or refrigerator door magnets. Electric mixers and blenders and a wide range of other electrical equipment may also have strong enough magnetism to affect timekeeping.

The best way to identify a watch is to look on the caseback at the back of the watch. The calibre number is the first four alphanumeric numbers e.g. V732. The case number is the next four numbers e.g. 5A30.

You should have received an instruction booklet when you purchased the watch. However, if you do not have one, instruction booklets can be downloaded from our SEIKO website.
