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)

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.

By distancing magnetism, 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.

 

For the solution of troubles other than above, contact the retailer from whom the watch
