      If your Seiko Watch stops, it might be because the mainspring's power is depleted. Try winding it by turning the crown or swinging the watch. If it still doesn't work after that, consider getting professional assistance.

      If your Seiko Watch stops, it might be because the mainspring's power is depleted. Try turning the crown or swinging the watch to wind it up. This should get it working again. If it still doesn't start, it is recommended to consult the retailer.

      If your Seiko Watch stops even when worn daily, it could be due to short wear times or minimal arm movement. Try wearing it for longer periods. Alternatively, wind the mainspring by turning the crown when you take it off.

    Why is my Seiko Watch gaining or losing time temporarily?

      Brandon CurryAug 11, 2025
      Temporary time gain or loss in your Seiko Watch can occur due to several reasons: - Exposure to extremely high or low temperatures for an extended period. Once the watch returns to a normal temperature, normal accuracy should resume. - Close contact with a magnetic object. Keep the watch away from magnetic sources, and normal accuracy should resume. - Dropping the watch, hitting it against a hard surface, or wearing it during active sports. - Exposure to strong vibrations. - Not overhauling the watch for more than 3 years.

      Kelly ClarkAug 15, 2025
      If the date on your Seiko Watch changes at noon instead of midnight, the AM/PM setting may be incorrect. To fix this, advance the hands by 12 hours. Also, if the glass is blurred for a long time, it may indicate water damage, in such case it is recommended to consult the retailer.

      If your Seiko Watch temporarily gains or loses time, it might be due to extreme temperatures. Once the watch returns to a normal temperature, normal accuracy should resume. If the watch was exposed to a magnetic object, keep it away from the magnetic source. However, if the condition persists, consult the retailer.
