Why did my Seiko Watch stop working?
If your Seiko watch stops operating, it's likely that the energy has been depleted. To resolve this, recharge the watch sufficiently by exposing it to light.
What to do if my Seiko Prospex SSC813P Watch second hand doesn't move after charging?
If the stopped Seiko watch has been charged for longer than required, but the second hand doesn't resume one-second interval movement, it could be due to several reasons: the light the watch was exposed to was too weak (recharge the watch sufficiently by exposing it to light); the built-in IC has fallen into an unstable condition; the watch has been left or worn in extremely high or low temperatures (return the watch to a normal temperature so that it works accurately as usual, and then reset the time); or the watch has been left close to an object with a strong magnetic field (correct this condition by moving and keeping the watch away from the magnetic source).
Why is my Seiko Watch second hand moving at two-second intervals?
If the small second hand on your Seiko watch moves at two-second intervals, it indicates that the energy is running short. To fix this, recharge the watch sufficiently by exposing it to light.
Why does the date change during the day on my Seiko Prospex SSC813P Watch?
If the date on your Seiko watch changes during the day, it means the time is set 12 hours ahead of or behind the correct time. To solve this, reset the time correctly.
Why is the glass clouded on the inner surface of my Seiko Prospex SSC813P?
If the inner surface of the glass on your Seiko watch is clouded, it indicates that moisture has entered the watch because the gasket has deteriorated.
