LUMIBRITE
〔IF YOUR WATCH HAS LUMIBRITE〕
LumiBrite is a luminous paint that is completely to human beings and natural
environment, containing no noxious materials such as radioactive substance.
LumiBrite is a newly-developed luminous paint that absorbs the light in the dark.
For example, if exposed to a light of more than 500 lux for approximately 10 minutes,
LumiBrite can emit light 5 to 8 hours. Please note, however, that, as LumiBrite emits the
light it stores, the luminance level of the light decreases gradually over time. The dura-
tion of the emitted light may also differ slightly depending on such factors as the bright-
ness of the place where the watch is exposed to light and the distance from the light
source to the watch.
<Reference data on the luminance>

[Fine weather]: 100,000 lux [Cloudy weather]: 10,000 lux
（B）Indoor（Window-side during daytime）
[Fine weather]: more than 3,000 lux [Cloudy weather]: 1,000 to 3,000 lux
[Rainy weather]: less than 1,000 lux
（C）Lighting appartures（40-daylight fluorescent light）
[Distance to the watch: 1m]: 1,000 lux
[Distance to the watch: 3m]: 500 lux（average room luminance） [Distance to the watch: 4m]: 250 lux
