■LUMIBRITE WATCH
(dial, hands, buttons, case, bezel,
strap, etc.)
✼If your watch is a LORUS LUMIBRITE watch, it
has following features.
LORUS LUMIBRITE watches absorb and store light
energy from natural and artificial light sources and
emit light in the dark. They are made of
environmentally friendly material, and therefore, are
harmless to human beings and the environment.
•With a full charge, LORUS LUMIBRITE watches
glow in the dark hours longer than conventional
luminous watches of this type. If exposed to a
light of more than 500 lux (i.e., the brightness
of a typical office) for approximately 10 minutes,
or direct sunlight for 2 minutes, they will glow
for hours.
•Since LORUS LUMIBRITE watches emit the
light they store, the brightness will decrease
gradually over time. The length of time they will
glow may also differ slightly depending on such
factors as the brightness of and distance from
the light source used to charge the watch.
■BATTERY CHANGE
The miniature lithium battery SONY, Maxell or
Panasonic CR2016, which powers your watch,
should last approximately 2 years. However,
because it is inserted at the factory, the actual life
of the battery once in your possession may be less
than 2 years. Be sure to replace the battery to
prevent any possible malfunction as soon as it runs
down. To replace the battery, we recommend taking
the watch to a local watch repair shop.
■ CARE OF YOUR LORUS WATCH
This watch contains precise electronic components.
Never attempt to open the case or remove the back cover.
•BATTERY
CAUTION
Do not expose the old battery to fire
or recharge it. Keep it at a place
beyond the reach of children. If a
child swallows it, consult a doctor
immediately.
•WATER RESISTANT
*If your watch is 200 M/20 BAR, 100 M/10 BAR
or 50 M/5 BAR water resistant, it is so indicated
on the dial/case back.

•Do not operate the buttons when the watch is wet.
•If the watch is exposed to salt water, rinse it in
fresh water and then wipe it thoroughly dry.
•Should you find any water or condensation inside
the watch, immediately have it checked. Water
can corrode electric parts inside the case.
Caution:
Leather straps are not water resistant except so
indicated, even if the watch head is water resistant.
•ALLERGIC REACTION
Because the case and band touch the skin directly,
it is important to clean them regularly. If not, shirt
sleeves may be stained and those with delicate skin
may develop a rash. Please wear the watch with
some play to avoid any possible allergic reaction. If
you develop a rash on your wrist, stop wearing and
consult a physician.
•MAGNETISM/STATIC ELECTRICITY
Your watch will not be affected by magnetism
generated by household electric appliances but keep
your watch away from a place where the watch is
subject to strong electric field and static electricity.
•SHOCKS AND VIBRATIONS
Your watch may be worn for normal sports activities,
However, be careful not to drop it or hit it on hard
surfaces and avoid any severe impacts.
•TEMPERATURE
Your watch works with stable accuracy within a
temperature range between 0˚C and 50 ˚C. Do not
expose the watch to a place exceeding this
temperature range.
•CLEANING
Use only a soft cloth and clean water for cleaning
your watch. Never use chemicals, especially soap.
■SERVICE
When your LORUS watch requires repair or sevicing,
please see the enclosed WARRANTY/GUARANTEE.
