LUMIBRITE

LumiBrite is a newly developed luminous paint that is completely harmless to human beings

and the natural environment, containing no noxious materials such as radioactive substances.

LumiBrite absorbs the energy of sunlight or artificial light 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 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 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.

When you make a dive in dark water, LumiBrite may not emit light unless it has absorbed and

stored light sufficiently.

Before diving, therefore, be sure to expose the watch to light under the conditions specified

above, so that it fully absorbs and stores light energy. Otherwise, use the watch together with

an underwater flashlight.
