3. TROUBLESHOOTING
The watch stops operating.
1) The battery voltage has been
depleted.
2) The coil is broken.
3)
On e or m o r e whe e l s ha ve
been contaminated with dirt,
dust or other particles.
A
n excessive or insufficient
amount of lubricant has been
applied to the wheels.
Symptom Possible causes Solutions
The oscillating weight rotates
at an abnormally high rate,
and no charging is made.
1) The coil of the generating coil
block is broken.
2)
The pivot of the generating
rotor is broken.
(
The pinion of the generating
r o tor a n d th e ge a r o f t h e
i n t e r m e d i a t e w h e e l f o r
generating rotor are out of
mesh.)
1
)
Check the resistance of the
generating coil block. If the
coil is broken, replace the
generating coil block with a
new one.
2
)
R e move t h e br o ken p i e c e
of the generating rotor, and
replace the generating coil
bl o c k with a new one and
lubricate it appropriately.
(
O v e r h a u l a n d c l e a n t h e
relevant parts if necessary.)
1)
Charge the watch.
2) Replace the coil with a new
one.
3)
Remove dirt or dust and clean
the contaminate d w heels.
Lubricate the relevant wheels
with appropriate amount of
lubricant.
The oscillating weight does
not rotate.
1)
The gear of the oscillating
weight and the pinion of the
intermediate wheel are out of
mesh.
2)
The pivot of the generating
rotor is broken.
(
The pinion of the generating
r o tor a n d th e ge a r o f t h e
i n t e r m e d i a t e w h e e l f o r
generating rotor are out of
mesh.)
1) If the gear of the oscillating
weight and the pinion of the
intermediate wheel are intact,
reassemble them correctly.
2
)
R e move t h e br o ken p i e c e
of the generating rotor, and
replace the generating coil
bl o c k with a new one and
lubricate it appropriately.
(
O v e r h a u l a n d c l e a n t h e
relevant parts if necessary.)
The current consumption for
the movement exceeds the
standard value.
1)
When the measurement is
made, the IC is still in the
qui c k s t ar t mo de. (Whe n
th e c u r r e n t c o n s ump ti o n
measures about 200μA, it is
likely that the IC is in the quick
start mode.)
2)
The load applied on the gear
train has increased, and the
driving pulse to compensate
it has been generated.
1)
Af ter connecting the tester,
t u r n t h e c r o w n s e v e r a l
times, and then, make the
measurement again.
2 ) O v e r h a u l a n d c l e a n t h e
movement par ts, and then
make the measurement again.
The date star wheel does not
rotate.
The day star wheel does not
rotate.
1
)
The day starr wheel/the date
staar wheel and each jumper
are disengaged.
2

d a t e s t a r w h e e l an d e a c h
i n t e r m e d i a t e w h e e l a r e
disengaged.
Check the clearance of the date
star wheel and day star wheel.
Correct the defected parts.
