Unlike mechanical watches or con-
ventional quartz watches, LORUS
KINETIC®requires no windup springs
or batteries. Instead, it utilizes
the movement of the wearer as its
power source.

Notes:
1. For Cal. YT57, do not set the date between
9:00 p.m. and 1:00 a.m. For Cal. YT58, do
not set the day/date between 9:00 p.m.
and 3:00 a.m. Otherwise, the calendar
may not change properly. If it is neces-
sary to set the calendar during that time
period, first change the time to any time
outside it, set the calendar and then reset
the correct time.
2. When setting the hour hand, check that
AM/PM is correctly set. The watch is so
designed that the calendar changes once
a day.
3. When setting the minute hand, advance it
4 to 5 minutes ahead of the desired time
and then turn it back to the exact minute.
4. It is necessary to adjust the date at the
end of February and 30-day months.
■POWER RESERVE IN YOUR LORUS
KINETIC WATCH
•The electric energy generated while the
watch is worn on your wrist is stored in the
KINETIC ELECTRICITY STORAGE UNIT
(KINETIC E.S.U.). It is a power source
completelydifferentfromconventionalbatteries
for watches, and therefore, this watch does
not require battery replacement.
•The watch has been charged fully at the
factory. Normally, therefore, it is not nec-
essary to charge the watch by swinging it.
If you should find the second hand being at
a stop, however, charge the watch follow-
ing the procedure in “How to charge the
watch”.
1. When the watch stops completely, a few
swings will start the second hand moving
at two-second intervals. The watch, how-
ever, will run down shortly, if left untouched.
2. Swing the watch approximately 100 times.
There will be about 12 hours of power
reserve available.
3. Then, wear the watch on your wrist.
* Even if the watch is worn on your wrist, it
will not be charged while your arm is not in
motion.
* It is recommended that, before worn on
your wrist, the watch be swung further un-
til one day of power is reserved. As a guide-
line of recharging, an additional 200 swings,
about 300 swings in total, will reserve one
day of power. It is not necessary to charge
the watch fully, as it is charged automati-
cally while it is worn on your wrist.

■ FULL CHARGE OF THE KINETIC E.S.U.
•When the KINETIC E.S.U. is fully charged,
the watch will keep operating for a maxi-
mum of about 6 months without recharg-
ing the KINETIC E.S.U.
■REMARKS ON THE KINETIC E.S.U.
CAUTION
Never install a silver oxide battery
for conventional watches in place
of the KINETIC E.S.U. The battery
may burst, become very hot or
catch fire.
■ENERGY DEPLETION FOREWARNING
FUNCTION
•When the second hand starts moving at
two-second intervals instead of the normal
one-second intervals, the watch will run
down in approximately 12 hours. In this
case, swing the watch from side to side to
charge the KINETIC E.S.U. sufficiently.
* The watch remains accurate even while
the second hand is moving at two-second
intervals.
■INSTANT-START FUNCTION
•When a long time has passed since the
watch stopped, you can get it started quickly
with only a few swings.
•This function is available as long as the
watch has been stopped for less than a
year.
*When this function is activated, the sec-
ond hand will start moving at two-second
intervals. Swing the watch from side to
side to charge the KINETIC E.S.U. by re-
ferring to “How to charge the watch”.
* After the second hand starts moving at
one-second intervals, put the watch on your
wrist so that it will be charged further.
■PRECAUTION ON SEE-THROUGH
CASE-BACK MODELS
✩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.
■LUMIBRITE WATCH
(dial, hands, buttons, case, bezel, strap,
etc.)
•If your watch has a glass case back, do not
expose the case back to strong light such
as direct sunlight or an incandescent light
at close range, as this may temporarily
increase the power consumption of the watch
circuit, thus reducing the power reserve in
the KINETIC E.S.U. This condition, how-
ever, will be corrected when the case back
is turned away from the light.
*While you walk with your watch on your
wrist, swinging your arm will charge the
KINETIC E.S.U. more efficiently than merely
swinging the watch by hand.
If the watch is worn for 12 hours a day, about
36 hours (one and a half days) of power re-
serve will be newly accumulated every day.
Ex.:
If the watch is worn almost every day:
If the watch is worn for 12 hours a day
over a week, about 10 additional days of
power reserve is accumulated.

•The electric energy generated while the

Notes:
1. No additional benefit is obtained by swinging
the watch more quickly or with greater
vigor.
2. When the watch is swung, the oscillating
weight in the generating system rotates to
drive the mechanism. As it rotates, it
gives out a sound, which is not a malfunc-
tion.
3. The watch is equipped with a system to
prevent overcharge. Even if it is further
swung after being fully charged, no mal-
function will result.

•Swing the watch from side to side, making
an arc of about 20 cm.
•Swing rhythmically at a rate of twice a
second.
ies for watches, and therefore, this watch
does not require battery replacement.
•The KINETIC E.S.U. is a clean and envi-
ronmentally friendly power source.

When your LORUS watch requires repair
or servicing, please see the enclosed

indicated on the dial/case back.
•Do not operate the crown when the watch
is wet.
•If the watch is exposed to salt water, rinse
it in fresh water and then wipe it thoroughly
dry.
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
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.
