■TROUBLESHOOTING
Trouble
Possible cause
The watch stops operating.
(The chronograph hands do not move.)
The power supplied by the mainspring has been consumed.
Even though you wear the watch every day, the
power reserve indicator does not move up.
The watch is worn on your wrist only for a short period of
time, or the amount of arm movement is small.
The watch temporarily gains or loses time.
The watch has been left in extremely high or low tempera-
tures.
The watch has been left close to an object with a strong
magnetic field.
You drop the watch, hit it against a hard surface, or wear it while
playing active sports. The watch is exposed to strong vibrations.
The inner surface of the glass is clouded.
Moisture has entered the watch because the gasket has deteriorated.
The watch stops even though the power reserve
indicator is not showing "0."
The watch has been left at a temperature below 0℃ .
Right after starting the watch, it seems that the second
hand moves more quickly than usual when setting the time.
When starting the watch, it takes a little time before the
adjustment function starts working (this is not a malfunction).
The date changes during daytime.
AM/PM is not correctly set.
※ In the event of any other problem, please contact the retailer from whom the watch was purchased.
Solution
Wind the mainspring and reset the time. While you are wearing the watch or when you take it off, check the re-
maining power shown by the power reserve indicator and wind the mainspring if necessary.
Wear the watch for an extended period of time, or when taking off the watch, turn the crown to wind the main-
spring if the remaining power shown by the power reserve indicator is not sufficient for the next use.
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℃ and 35℃ .
Correct this condition by moving and keeping the watch away from the magnetic source. If this action does not
correct the condition, contact the retailer from whom the watch was purchased.
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.
Contact the retailer from whom the watch was purchased.
If the watch is left at a temperature below 0℃ , it may stop if the power reserve indicator is showing less than
one-sixth of the power reserve. In such a case, turn the crown to wind the mainspring.
It takes several seconds before the adjustment function starts working. Set the time after the second hand moves
for approximately 30 seconds to set the time correctly.
Advance the hour hands for 12 hours to correctly set the time and date.
Refer to "How to manually wind the mainspring by turning the crown" on page 54. Refer to "How to set the time" on page 57.
