Problems Methods of repair and checking
The quickness of the
hand movement after
the activation of the
time relay function has
reduced a little.
1) Check the resistance of the coil for
detecting generation. Replace the hour
and minute coil block if the coil is broken.
Page 15
The oscillating weight
rotates at an abnormally
high rate, and no
charging is made.
1) Check the resistance of the generating
coil block. Replace the generating coil
block if the coil is broken.
2) Remove the broken piece of the
generating rotor, and replace and
lubricate the generating rotor. (Overhaul
and clean if necessary.)
Possible causes
1) The coil for detecting
generation of the hour and
minute coil block is broken.
1) The coil of the generating
coil block is broken.
2) The pivot of the generating
rotor is broken. (The pinion
of the generating rotor and
the gear of the intermediate
wheel for generating rotor
are out of mesh.)
The oscillating weight
will not rotate.
1) If the gear of the oscillating weight and
the pinion of the intermediate wheel for
generating rotor are intact, reassemble
them to the movement.
2) Remove the broken piece of the
generating rotor, and replace and
lubricate the generating rotor. (Overhaul
and clean if necessary.)
Page 101) The gear of the oscillating
weight and the pinion of the
intermediate wheel for
generating rotor are out of
mesh.
2) The pivot of the generating
rotor is broken. (The pinion
of the generating rotor and
the gear of the intermediate
wheel for generating rotor
engage with each other.)

The current consump-
tion for the whole of the
movement exceeds the
standard value.
1) After connecting the tester, move the
oscillating weight more quickly for a
longer period of time, and then, make
the measurement again.
2) If the current consumption for the circuit
block alone is within the standard value
range, overhaul and clean the movement
parts, and then, make the measurement
again.
Page 161) When the measurement is
made, the IC is still in the
quick start mode. (When the
current consumption
measures about 200 µA, it is
likely that the IC is in the
quick start mode.)
2) The load applied on the gear
train, etc. has increased, and
the driving pulse to compen-
sate it has been generated.

The current consump-
tion for the circuit block
alone exceeds the
standard value.
1) Shut out the light, and make the
measurement again.
2) Switch the IC to the normal mode, and
make the measurement again.
3) Replace the circuit block.
Page 171) The light from outside the
movement is affecting the
measurement.
2) When the measurement is
made, the IC is still in the
quick start mode. (When the
current consumption
measures about 200 µA, it is
likely that the IC is in the
quick start mode.)
3) The IC is out of order.

The manual power save
function cannot be
activated.
1) Swing the watch until the second hand
moves at one-second intervals, and then,
check if the manual power save function
is activated.
2) Check if the power save switch lead pin
is set in position. Check if the yoke
functions properly.
3) Check if the spring portion of the yoke
catches the pin of the movement while
making contact with it.
Page 181) The energy depletion
forewarning function is in
operation.
2) The power save switch lead
pin is not in contact with the
yoke.
3) The yoke and the movement
do not conduct electricity.
