    Why is my Grand Seiko Watch gaining or losing time?
    • C
      Chad SnyderJul 29, 2025
      If your Grand Seiko Watch is temporarily gaining or losing time, it might be due to a few reasons. First, check if the watch has been exposed to extremely high or low temperatures for an extended period. If so, allow the watch to return to a normal temperature, and then readjust the time. Normal accuracy should resume. Another cause could be close contact with a magnetic object. Distance the watch from the magnetic source to recover accuracy, then readjust the time. If neither of these resolves the issue, consider whether the watch has been dropped, subjected to active sports, hit against hard surfaces, or exposed to strong vibrations. In this case, readjust the time. If accuracy is still not recovered after these steps, it is best to consult the retailer from whom the watch was purchased.

      If the date on your Grand Seiko Watch changes during the daytime, it's likely that the a.m./p.m. setting is not correctly configured. To resolve this, advance the hour hand by 12 hours and then reset the time and date accordingly.

      Steven WardAug 22, 2025
      If you notice persistent blur in the display of your Grand Seiko Watch, it suggests that a small amount of water has entered the watch, possibly due to the deterioration of the gasket or other components. In this situation, it is recommended to consult the retailer from whom the watch was purchased.
