NOTES ON OVERHAUL
The watch is a precision device with many moving parts lubricated with special
oils. If the parts run short of oil or get worn out, the watch may lose time or stop
operation. In such a case, have the watch overhauled.
PLACES TO KEEP YOUR WATCH
Do not leave the watch in a place where the temperature drops below 5 °C (41 ° F)
or rises above 35 °C (95 °F) for a long time.
Do not leave the watch in a place where it will be subjected to strong magnetism
(for example, near television sets, loudspeakers or magnetic necklaces) or static
electricity.
Do not leave the watch where there are strong vibrations.
Do not leave the watch in dusty places.
Do not expose the watch to chemical substances or gases.
(Ex.: Organic solvents such as benzine and thinner, gasoline, nail polish, cosmetic
sprays, detergents, adhesives, mercury, and iodine antiseptic solution.)
Do not leave the watch in close contact with hot spring water.
LUMIBRITETM
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.
