Why has my Seiko SSC141P1 stopped working?
- BBrandon DeckerAug 6, 2025
If your Seiko Watch stops operating, it is likely that the energy has been depleted. Recharge the watch sufficiently by exposing it to light.
Why has my Seiko SSC141P1 stopped working?
If your Seiko Watch stops operating, it is likely that the energy has been depleted. Recharge the watch sufficiently by exposing it to light.
Why does the date on my Seiko SSC141P1 Watch change during the day?
If the date on your Seiko Watch changes during the day, the time is likely set 12 hours ahead of or behind the correct time. Reset the time correctly, referring to “SETTING THE TIME AND ADJUSTING STOPWATCH HAND POSITION.”
What to do if Seiko SSC141P1 Watch doesn't resume normal after charging?
If your Seiko Watch has been charged for longer than required, but the second hand does not resume one-second interval movement, consider these possible causes: 1. The light the watch has been exposed to was too weak. Recharge the watch referring to "GUIDELINE OF CHARGING TIME/ACCURACY." 2. The built-in IC has fallen into an unstable condition. Reset the watch by following the instructions in “IMPROPER FUNCTION." 3. 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. 4. 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 the second hand on my Seiko SSC141P1 Watch 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 resolve this, recharge the watch sufficiently by exposing it to light.
How to fix Seiko SSC141P1 when stopwatch hands don't return to zero?
If the STOPWATCH hands on your Seiko Watch do not return to the "0" position when the stopwatch is reset, it may be affected by external sources, or because the internal IC had been reset, the stopwatch hand positions have moved out of correct alignments. To fix this, adjust the STOPWATCH hands to the "0" position by following the instructions in “SETTING THE TIME AND ADJUSTING STOPWATCH HAND POSITION.”
