FEATURES  
SEIKO KINETIC Cal. 7L22 is an analogue quartz watch equipped with an Autom atic  
Generating System developed by SEIKO. It generates the electric energy to power the  
watch, utilizing the m ovem ent of the arm , and stores it in the KINETIC ELECTRICITY  
STORAGE UNIT (KINETIC E.S.U.), which requires no periodical replacem ent unlike  
conventional button-type batteries.  
HOW TO CHARGE AND S TART THE WATCH  
Swing the watch from side to side approxim ately 500 tim es.  
1
*
Swing rhythmically at a rate of twice a second.  
*
500 swings will start the watch and the second hand will move at one-second intervals.

3
Swing the watch approxim ately 200 tim es further to reserve one day of power.  
Set the tim e/calendar and put on the watch.

P OWER RES ERVE IN YOUR S EIKO KINETIC WATCH  
The electric energy generated while the watch is worn on your wrist is stored in the  
KINETICELECTRICITYSTORAGEUNIT(KINETICE.S.U.). It is a power source completely  
different from conventional batteries for watches, and therefore, does not require any  
periodical replacem ent.  
The KINETIC E.S.U. is a clean and environm entally friendly power source.  
Pow er reserve guidelines for the KINETIC E.S.U.  
You can estimate the power reserve accumulated in the KINETICE.S.U. from the manner  
in which you wear the watch.  
Wearing the watch continuously for 12 hours will accum ulate approxim ately two  
additional days of power reserve.  
If you wear the watch every day for 12 hours for a m onth, for exam ple, two additional  
m onths of power will be reserved.  
Full charge  
When the watch is fully charged, the watch will keep operating for approxim ately  
5 months. The duration ofcharge decreases gradually over time. The extent ofdecrease,  
however, varies depending on the environm ent and condition of use.  
Precautions for those only w earing the w atch occasionally  
If you use the watch only occasionally, it is likely that you will find the watch running  
down when you decide to use it. Before wearing the watch,be sure to charge it sufficiently  
following the procedure in “HOW TO CHARGE AND START THE WATCH”.

REMARKS ON THE KINETIC E.S .U.  
Do not pull the crown out to the second click with the intention of stopping the second  
hand just to save energy. By doing so, a large am ount of current flows through the  
built-in IC. Therefore, pulling out the crown to the second click will not save energy  
but, in fact, consum e m ore energy than usual.  
CAUTION  
Never install a silver oxide battery for conventional w atches in place of the KINETIC  
E.S.U. The battery m ay burst, becom e very hot or catch fire. Even if the battery  
is installed, electricity w ill not be conducted.  
ENERGY DEP LETION FOREWARNING FUNCTION  
When the second hand starts m oving at two-second intervals instead of the norm al  
one-second intervals, the watch will run down in approxim ately 12 hours.  
*
If the second hand starts moving at two-second intervals while the stopwatch is in use, the watch will  
run down in approximately 45 minutes assuming the stopwatch remains in use. (Refer to HOW TO  
CHARGE AND START THE WATCH.)  
In this case, swing the watch from side to side to sufficiently charge the KINETIC E.S.U.

The stopwatch can m easure up to 45 m inutes in 1/5 second increm ents.  
The m easured tim e is indicated by two STOPWATCH hands that m ove independently  
of the hands for tim e indication.  
After 48 m inutes, the stopwatch will stop autom atically.  
TIP S ON READING THE HANDS  
The STOPWATCH second hand turns a full circle in 60 seconds.  
The STOPWATCH m inute hand m oves in one-m inute increm ents up to 45 m inutes. It  
m oves accordingly as the STOPWATCH second hand m oves. Please note that the

S TOP WATCH OP ERATION  
Before using the stopw atch, be sure to reset the STOPWATCH hands to “0” position.  
1) Check that the watch is operating norm ally.  
* If the watch has stopped completely or if the second hand is moving at two-second intervals, charge  
the watch sufficiently. (See “HOW TO CHARGE AND START THE WATCH)  
2) Press button B to reset the STOPWATCH hands to “0” position.  
* When using the stopwatch for the first time after the watch has been charged to start operation, be  
sure to reset the stopwatch even if the STOPWATCH hands are at “0” position.

NOTES FOR US ING THE WATCH  
HOW TO CHARGE AND START THE WATCH  
To charge the KINETIC E.S.U. efficiently, swing the watch from side to side rhythmically at a rate of twice  
a second, making an arc of about 20 cm.  
No additional benefit is obtained by swinging the watch more quickly or with greater vigor.  
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 malfunction.  
If you find the second hand moving at two-second intervals after swinging the watch approximately 500  
times, swing it further until the second hand moves at the normal one-second intervals.  
The watch is equipped with a system to prevent overcharge. Even if it is further swung after being fully  
charged, no malfunction will result.  
It is not necessary to charge the watch fully, as it is charged automatically while it is worn on your wrist.  
Wear the watch daily for at least 10 hours.  
Even if the watch is worn on your arm, it will not be charged while your arm is not in motion.  
POWER RESERVE IN YOUR SEIKO KINETIC WATCH  
Precaution on see-through case-back m odels:  
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, however, will be  
corrected when the case back is turned away from the light.  
ENERGY DEPLETION FOREWARNING FUNCTION  
The watch remains accurate even while the second hand is moving at two-second intervals.  
If the stopwatch continues to be used after the second hand starts moving at two-second intervals, the  
movement of the stopwatch hands may become unstable immediately before the watch stops  
completely.  
 
13  
TIME/ CALENDAR SETTING  
Do not set the date between 9:00 p.m. and 1:00 a.m. Otherwise, it may not change properly. If it is  
necessary to set the date during that time period, pull out the crown to the second click and turn it  
counterclockwise to advance the time ahead of 1:00 a.m., and push the crown to the first click to set  
the date and then reset the correct time.  
When setting the hour hand, check that AM/PM is correctly set. The watch is so designed that the  
calendar changes once in 24 hours.  
Turn the hands past the 12 oclock marker to determine whether the watch is set for the A.M. or P.M.  
period. If the date changes, the time is set for the A.M. period. If the date does not change, the time  
is set for the P.M. period.  
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.  
When setting the time, make sure that the second hand is moving at one-second intervals.  
It is necessary to adjust the date at the end of February and 30-day months.  
In this case, pull out the crown to the first click and turn it counterclockwise until the desired date appears.  
STOPWATCH  
You may feel that the buttons of the watch are harder to press compared with those of conventional  
watches. This is due to the special construction needed for the stopwatch function, and, therefore, is  
not a malfunction.  
While the stopwatch is being used, the watch consumes 5 to 6 times the amount of energy required by time  
indication alone. Before using the stopwatch, therefore, make sure that the watch is charged sufficiently.  
If the stopwatch continues to be used while the second hand is moving at two-second intervals, the  
watch will run down within 45 minutes.  
After operating for 48 minutes, the stopwatch will stop automatically. If the stopwatch minute hand  
stops at the position over 45 minutes indicator, reset the stopwatch before next use.  
While the stopwatch is measuring, pressing button B will reset the stopwatch. Be careful not to press  
button B by mistake.  
Do not press buttons A and B at the same time, nor press one of the two buttons while keeping the other  
pressed. Otherwise, a malfunction will result.
