Why does my Seiko Cal. V198 gain or lose time?

  Your Seiko Watch may gain or lose time because it has been exposed to extremely high or low temperatures. Return the watch to a normal temperature so that it works accurately as usual, and then reset the time. It can also happen if the watch has been left close to an object with a strong magnetic field; move the watch away from the magnetic source. Also, check if you have dropped the watch, hit it against a hard surface, or exposed it to strong vibrations; if so, reset the time.

  If the date on your Seiko Watch changes during the day, it means that the time is set 12 hours ahead of or behind the correct time. Reset the time correctly, referring to 'TIME SETTING AND HAND POSITION ADJUSTMENT'.

  If the small second hand on your Seiko Watch is moving at two-second intervals, it indicates that the energy is running short. To resolve this, recharge the watch sufficiently by exposing it to light.

  Kim KhanAug 21, 2025
  If the STOPWATCH hands on your Seiko watch do not return to the '0' position when the stopwatch is reset, it may be that the stopwatch hand positions have moved out of correct alignments. Adjust the STOPWATCH hands to the '0' position by following the instructions in 'TIME SETTING AND HAND POSITION ADJUSTMENT'.

What to do if charged Seiko Watch second hand does not resume one-second interval movement?
- N
  nfloresAug 27, 2025
  If your Seiko watch has been charged for longer than the time required for full charge, but the second hand does not resume one-second interval movement, the light the watch has been exposed to may have been too weak, so recharge the watch sufficiently by exposing it to light. Alternatively, the built-in IC may have fallen into an unstable condition, so reset the watch by following the instructions in 'IMPROPER FUNCTION'.
