Troubleshooting
Troubles Possible causes Solutions
The watch stops operating.
The mainspring has not been
wound.
Turn the crown to wind the mainspring and
reset the time. While you are wearing the
watch or when you take it off, check the
remaining power shown by the power
reserve indicator and wind the mainspring
if necessary.
The watch stops even though
the power reserve indicator is
not showing “0”.
The watch has been left at a low
temperature (below 0°C).
Turn the crown to wind the mainspring.
Under a low-temperature condition (below
0°C), the watch may stop when the power
reserve indicator shows less than one-sixth
of the power reserve.
The watch temporarily loses/
gains time.
The watch has been left in
extremely high or low
temperatures for a long time.
Return the watch to a normal temperature
so that it works accurately as usual, and
then reset the time. The watch has been
adjusted so that it works accurately when it
is worn on your wrist under a normal
temperature range between 5°C and 35°C.
The watch was brought into
close contact with a magnetic
object.
Correct this condition by moving and
keeping the watch away from the magnetic
source, and reset the time. If this action
does not correct the condition, contact the
retailer from whom the watch was
purchased.
The watch was dropped, worn
while playing active sports, hit
against hard surfaces, or
exposed to strong vibrations.
Reset the time. If the watch does not return
to its normal accuracy after resetting the
time, contact the retailer from whom the
watch was purchased.
The watch hands move quicker
than usual.
This is not a malfunction.
1. Conduct the following crown operation.
Normal position → first click → normal
position
2. Reset the time.
Right after starting the watch, it
seems that the seconds hand
moves more quickly than usual
when setting the time.
When the watch starts moving,
it takes a little time before the
speed-regulating unit starts
operating. (This is not a
malfunction.)
It takes several seconds before the speed-
regulating unit starts operating.
To set the time correctly, wait for
approximately 30 seconds after the
seconds hand starts to move, and set the
time.
Blur in the display persists.
This condensation temporarily
occurs due to a temperature
difference between the inside of
the watch and the outside
environment.
Condensation will clear when the
temperature difference is reduced. No
repair is needed.
Moisture has entered the watch.
Consult the retailer from whom the watch
was purchased.

The time indicated by the
number of times the gongs are
struck is not the same as the time
indicated by the hour and minute
hands.
As the minute repeater is a
mechanically-actuated time
announcing device, an error of
approximately one minute may
occur between the time
indicated by the number of times
the gongs are struck and the
time indicated by the hands of
the watch.
If an error of a few minutes is observed,
consult the retailer from whom the watch
was purchased.
The mainsprings cannot be
wound.
The crown cannot be pulled out.

chiming, the mainsprings are
completely unwound,
preventing the safety device
from being released.
Release the safety device following the
instructions in this booklet. (P. 15)
The minute repeater does not
chime.
