Lumibrite
If your watch has Lumibrite
Lumibrite is a luminous paint that absorbs the 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, 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.
