Magnetic resistance (Magnetic influence)
Affected by nearby magnetism, a watch may temporarily gain or lose time or stop operating.
Indication on the case back Conditions of use Certified level
Keep the watch more than 5 cm away from
magnetic products.
4,800 A/m
Keep the watch more than 1 cm away from
magnetic products.
16,000 A/m
* A/m (ampere meter) is the international unit (SI unit) for indicating the magnetic field.
If the watch becomes magnetized and its accuracy deteriorates to an extent exceeding the specified rate under normal
use, the watch may need to be demagnetized. In this case, you will be charged for demagnetization and accuracy
readjustment even if it happens within the guarantee period.

The reason why this watch is affected by magnetism
The built-in speed-regulating mechanism is provided with a magnet, which may be influenced by a strong external
magnetic field.

Lumibrite
If your watch has Lumibrite
Lumibrite is a newly-developed luminous paint that absorbs light energy of the sunlight and lighting apparatus in a
short time and stores it to emit light in the dark. For example, if exposed to a light of more than 500 lux for approximately
10 minutes, Lumibrite can emit light for 3 to 5 hours. Please note, however, Lumibrite emits the light it stores, the
luminance level of the light decreases gradually over time. The duration of the emitted light may also differ slightly
depending on such factors as the brightness of the place where the watch is exposed to light and the distance from
the light source to the watch.
* In general, when you enter a dark place from a bright environment, your eye cannot adapt to the change in light
levels quickly. At first, you can hardly see anything, but as time passes, your vision gradually improves. (Dark
adaptation of the human eye)
* Lumibrite is a luminous paint that is completely harmless to human beings and the natural environment; containing
no noxious materials such as radioactive substance.

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. If this action does not correct the condition,
consult the retailer from whom the watch was
purchased.
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 and reset the
time. At a temperature below 0°C, the watch may stop
if the power reserve indicator is showing 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 has been left close to an
object with a strong magnetic field.
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.
You drop the watch, hit it against a
hard surface, or wear it while playing
active sports.
The watch is exposed to strong
vibrations.
If accuracy does not return after setting the time, consult
the retailer from whom the watch was purchased.
