      If your Seiko Watch isn't charging, make sure it's getting enough light. The charging time depends on how much light it receives. Check the "Standard charging time" section for guidance.

      If your Seiko Watch isn't starting reception even after adjusting the time zone or manually adjusting the time, ensure the watch is sufficiently charged, until the charging status displays as the middle or full position. Also, if the in-flight mode is enabled, disable it after moving from a place where GPS signals are restricted, such as an airplane.

    What to do if Seiko 8X53 Watch time and date are wrong after GPS sync?

      Lawrence EverettAug 13, 2025
      If your Seiko Watch displays the wrong time and date after a successful GPS signal reception, it might be due to an incorrect time zone setting. Verify that the time zone corresponds to your current region and adjust it if necessary. Also, check the DST (Daylight Saving Time) setting to ensure it matches the DST conditions.

      If your Seiko Watch isn't receiving GPS signals, try charging it by exposing it to light until the indicator hand points to the middle or full position.

    Why did my Seiko 8X53 second hand stop at 45 and start again?
    • A
      Amanda PenningtonAug 21, 2025
      If the second hand on your Seiko Watch stops at the 45-second position and then starts moving again, it means the power save function 2 has activated. Charge the watch until the indicator hand points to the middle or full position. If the time is still incorrect after charging, adjust the time zone.

      If your Seiko Watch isn't receiving GPS signals, even when attempting GPS signal reception and the result is displayed as "N,", you may be in a location where GPS signals are weak or unavailable. Try moving to a place where GPS signals can be received more easily.
