Lumibrite

If your watch has Lumibrite
Lumibrite is a luminous paint that absorbs the light energy of sunlight and lighting apparatuses 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, that, as 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 coming from a place that is bright to a place that is dark, it takes human eyes some time to adapt
to the darkness making it difficult to see objects initially. (Dark adaptation)
* Lumibrite is luminous paint that stores and emits light, which is harmless to human beings and the environment,
containing no toxic materials such as radioactive substances.

Magnetic resistant performance
Affected by nearby magnetism,
a watch may temporarily gain or lose time or stop operating.
b DANGER
Indication on the case back
No indication
Keep the watch more than 5 cm away from magnetic products.
Keep the watch more than 1 cm away from magnetic products.
If the watch becomes magnetized and its accuracy deteriorates to an extent exceeding the specified rate
under normal use, the watch needs 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 a watch is affected by magnetism
The built-in balance spring may be influenced by a strong external magnetic field.
