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.
