What is "Grand Seiko Standard"?

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.

  • * 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.
What is "Grand Seiko Standard Inspection Certificate"?

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.
Can I get my Grand Seiko Standard Inspection Certificate reissued?

The Grand Seiko Standard Inspection Certificate cannot be reissued.

How accurate is Grand Seiko?

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.
What is the accuracy of the mechanical watch in use / the mechanical watch movement at rest?

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."

Why doesn’t the accuracy of my Grand Seiko mechanical watch match the rate written on the Grand Seiko Standard Inspection Certificate?

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.

How to take care of my Grand Seiko watch?

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.
What is the polishing service?

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.
