      The power save function has been activated because the watch was not exposed to enough light for a certain period, which limits energy consumption. When taking off the watch, place it in as bright a location as possible.

      If the hands on your Seiko Watch are advancing rapidly unless a button is pressed, the power save function and the automatic hand position alignment function have been activated. Wait until the current time is displayed.

      Lucas HolmesAug 28, 2025
      If the second hand position on your Seiko Watch is not correctly aligned in 'the reception results display' or 'the reception level display' due to external influence, the automatic hand position adjustment function will activate to align the hand positions. No crown or button operation is needed.

    How to fix Seiko C-20 second hand moving at two-second intervals?
    • W
      wongjustinAug 27, 2025
      If the second hand on your Seiko Watch is moving at two-second intervals, it indicates that the energy is running short. Fully charge the watch to restore the second hand movement to one-second intervals.

    Why won't my Seiko C-20 Watch resume normal movement after charging?
    • E
      Eric BullockAug 25, 2025
      If your Seiko Watch doesn't resume its normal one-second interval movements after being exposed to light, the amount of light may be too weak, or the charging time may not be sufficient. Refer to the 'GUIDELINE OF CHARGING TIME' to ensure adequate charging.

    Mr. Grant AguirreAug 23, 2025
    Why does my Seiko C-20 Watch gain or lose time?
    • T
      Tamara BooneAug 23, 2025
      Your Seiko Watch may be gaining or losing time because it is not receiving a radio signal correctly due to external influences. Try placing the watch in a location where it can receive a radio signal more easily.
