1. Pull out the crown to the second click
when the small second hand is at the 12
o’clock position.
* If the stopwatch is measuring or stopped, it is
automatically reset to “0”.
2. Turn the crown to set the hour and minute

■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 battery SEIKO SR927SW, Maxell
SR927SW, SONY SR927SW or EVEREADY 395,
which powers your watch should last approximately
3 years. However, because it is inserted at
the factory, the actual life of the battery once
in your possession may be less than the specified
period.
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.
Notes:
1. If the stopwatch is used for more than 3
hours a day, the battery life may be less
than the specified period.
2. After the battery is replaced with a new
one, set the time/calendar and adjust
the stopwatch hand position.
Battery life indicator
•When the battery nears its end, the small
second hand moves at two-second intervals
instead of normal one-second intervals. In
that case, have the battery replaced with a
new one as soon as possible.
•The watch remains accurate, however, while
the small second hand is moving at two-
second intervals.

■CARE OF YOUR LORUS WATCH
CAUTION
Do not expose the old battery to
fire or recharge it. Keep it at a
place beyond the reach of chil-
dren. If a child swallows it,
consult a doctor immediately.

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
Your watch will not be affected by mag-
netism generated by household electric
appliances.
• SHOCKS AND VIBRATIONS
Your watch may be worn for normal sports
activities, but be careful not to drop it or
hit it on hard surfaces.
• TEMPERATURE
Your watch is preadjusted so that constant
accuracy may be insured at normal tem-
perature.
