Support
Each and every Grand Seiko watch is designed and manufactured with reliability and durability in mind. The same dedication to the long-term satisfaction of all Grand Seiko owners guides our policies in after-sales care, which we are committed to improving.
The after-sales service network of Grand Seiko is designed to be global, in which technicians with advanced expertise and high-technology equipment are dedicated to meeting the needs of our customers. The global Grand Seiko service network hold extensive inventories of all the components required to maintain all Grand Seiko watches for the longest possible period, and in many cases, even many years after a watch has ceased to be produced.
We do not set any definitive limit to the repair period for any Grand Seiko watch and we intend to give our utmost attention to each watch brought to our authorized service center. It is our aim to ensure that every Grand Seiko watch can be worn and enjoyed for a longest possible time, ideally a lifetime or longer. Of course, we cannot guarantee that every original component will be available for ever but our aim is to offer industry-leading levels of after-sales care and to ensure the complete satisfaction of our customers in the long term.
Grand Seiko Complete Service
“Grand Seiko Complete Service” is a repair service in which an interior/overhaul is performed together with a “Light polish” in a set. A “Light polish” burnishes the surface of a watch case and metal band to make them look shiny.

FAQs
The 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.
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.
The Grand Seiko Standard Inspection Certificate cannot be reissued.
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.
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 mechanical 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 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.
To ensure that your watch remains in perfect working order, please take the following simple procedures:
- Avoid putting the watch too close to strong magnetic fields such as those generated by large TV sets or other large electronic devices.
- When you take the watch off, wipe away any moisture with a soft cloth. This will help enhance the life of the case and gaskets.
- If the watch is exposed to salt water, wash it in fresh water.
- Do not leave your watch in a place where the temperature drops below 5°C or rises above 35°C for prolonged periods.
- If your watch has a mechanical movement, try not to leave the watch unworn for too long. Your Grand Seiko watch performs best when worn for at least 10 hours a day.
- We recommend that you have your watch checked and overhauled periodically. Optimally, this should be done every three to four years.
As time goes by, it is possible that you may scratch your watch slightly. We hope this never happens, but if it does, we have a special polishing service available.
You might like to have your watch polished when it is with us for a normal service. Please consult your Grand Seiko retailer for details.
This Grand Seiko polishing service is performed by our very best craftsmen and women. Please take note of the following points:
- Polishing of certain parts may not be possible due to their special construction or material.
- If the damage is severe, it may not be possible to remove it by polishing alone.
- The finish may be very slightly different from the original, as the polishing is done by hand.
- The crown, pushers, case back and the emblem on the band cannot be polished.
