Lumibrite; Troubleshooting - Seiko QUARTZ 9F83 Operating Instructions Manual

Lumibrite

If your watch has Lumibrite
Lumibrite is a luminous paint that is completely harmless to human beings and
the natural environment; containing no noxious materials such as radioactive
substance. 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)
