Lumibrite
If your watch has Lumibrite
Lumibrite is a luminous paint that is completely harmless to human beings and
the natural environment; containing no noxious materials such as radioactive
substance. Lumibrite is a newly-developed luminous paint that absorbs 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, 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.
※
In general, when you enter a dark place from a bright environment, your eye cannot
adapt to the change in light levels quickly. At first, you can hardly see anything, but as
time passes, your vision gradually improves. (Dark adaptation of the human eye)

Troubleshooting
Troubles
Possible Causes
Solutions
The watch stops
operating.
The battery runs down.
Consult the retailer from whom
the watch was purchased.
The watch
temporarily gains/
loses time.
The watch has been left in
e x t r e m e l y h i g h o r l o w
temperatures for a long time.
Normal accuracy will resume
when the watch returns to
normal temperature. Readjust
the time.
The watch was brought
into close contact with a
magnetic object.
B y d i s t a n c i n g m a g n e t i s m ,
accuracy is recovered. Readjust
the time. If accuracy is not
recovered, consult the retailer from
whom the watch was purchased.
The watch was dropped, worn
while playing active sports, hit
against hard surfaces, or
exposed to strong vibrations.
Readjust the time. If accuracy
is not recovered, consult the
retailer from whom the watch
was purchased.
The second hand
moves at two-second
intervals.
The battery nears its end. Consult the retailer from whom
the watch was purchased.
The date changes
during daytime.
A.m./p.m. is not correctly
set.
Advance the hour hand for 12
hours and reset the time and date.
Blur in the display
persists.
Small amount of water has got
inside the watch due to
deterioration of the gasket, etc.
Consult the retailer from whom
the watch was purchased.
