LUMIBRITETM English LumiBrite is a luminous paint that is completely harmless to human beings and the natural environment, containing no noxious materials such as radioactive substances. LumiBrite is a newly-developed luminous paint that absorbs the light 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. < Reference data on luminance > (A) Sunlight [Fine weather]: 100,000 lux [Cloudy weather]: 10,000 lux (B) Indoor (Window side during daytime) [Fine weather]: more than 3,000 lux [Rainy weather]: less than 1,000 lux [Cloudy weather]: 1,000 to 3,000 lux (C) Lighting apparatus (40-watt daylight fluorescent light) [Distance to the watch: 1 m]: 1,000 lux [Distance to the watch: 3 m]: 500 lux (average room luminance) [Distance to the watch: 4 m]: 250 lux * "LUMIBRITE" is a trademark of SEIKO HOLDINGS CORPORATION. 22 English SPECIFICATIONS 1 Frequency of crystal oscillator 2 Loss/gain (monthly rate 3 Operational temperature range 4 Driving system 5 Power supply 6 Additional function 7 IC (Integrated Circuit 32,768 Hz (Hz = Hertz ...
