LUMIBRITE
If your watch has Lumibrite
Lumibrite is a 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 lumi-
nance level of the light decreases gradually over time. The duration of the
emitted light may also dier slightly depending on such factors as the
brightness of the place where the watch is exposed to light and the dis-
tance from the light source to the watch.
※ In general, when coming from a place that is bright to a place that is dark, it takes hu-
man eyes some time to adapt to the darkness making it dicult to see objects initially.
(Dark adaptation)
※ Lumibrite is luminous paint that stores and emits light, which is harmless to human be-
ings and the environment, containing no toxic materials such as radioactive substances.

■ Inspection and adjustment by disassembly
and cleaning (overhaul)
・ Periodic inspection and adjusment by disassembly and
cleaning (overrhaul) is recommended approximately once
every 2 to 3 years in order to maintain optimal performance
of the watch for a long time. According to use conditions,
the oil retaining condition of your watch mechanical parts
may deteriorate,abrasion of the parts due to contamination
of oil may advance or delay the time significantly, or the
watch itself may stop. As parts such as a gasket may dete-
riorate, water-resistant performance may be impaired due
to intrusion of perspiration and moisture. Please contact the
retailer from whom the watch was purchased for inspection
and adjustment by disassembly and cleaning (overhaul). For
replacement of parts, please specify SEIKO GENUINE
PARTS. When asking for inspection and adjustment by dis-
assembly and cleaning (overhaul), make sure that the gas-
ket and push pin are also replaced with new ones.
・ When your watch is inspected and adjusted by disassem-
bly and cleaning (overhaul), the movement of your watch
may be replaced.
