Lumibrite

［IF YOUR WATCH HAS LUMIBRITE］

LumiBrite is a luminous paint that is completely harmless to human beings and natural environment, containing no noxious materials such as radioactive sub- stance.

LumiBrite is a newly-developed 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 ex- posed to light and the distance from the light source to the watch.
