Troubleshooting
Symptoms
Problems
Solutions
The watch stops.
The battery is weak or dead.
The hands are worn out.
The coil is burned out.
The wheels are soiled with dirt
and dust. The amount of oil is
excessive(wringing) .
Measure the battery voltage. Change the battery.
Change the hands.
Measure the coil block resistance. Change the
coil block.
Remove all dust or dirt. Clean up the relevant
parts. Be careful not to damage the teeth of the
plastic parts while cleaning.
The current consumption
for the whole movement
is excessive.
Dirt, dust or chips are adhere to
the movement.
The driving pulse is generated due
to the excessive load to the wheels.
(The oil is deteriorated, leaked or
ran out.)
Measure the current consumption for the circuit
block alone. If the result is within the standard
range, overhaul and clean the movement parts,
and then measure the current consumption for
the whole movement again.
The date or day hand
dose not move.
