FEATURES

SEIKO KINETIC Cal. 5M85 is an analogue quartz watch equipped with the Kinetic technology developed by SEIKO. It generates the electric energy to power the watch, utilizing the movement of your body, and stores it in the rechargeable battery, which requires no periodical replacement unlike conventional button-type batteries.

The wat ch is equipped with a 24 -hour hand and features an hour-hand independent adjustment function (for time difference adjustment), offering several typ es of 24 -hour hand usa ge. For instance, if you set the 24-hour hand to show your home time, you c an inde pendently s et the hour hand to display the time of the place you are staying at as well as ea sily check your home tim e with the 24hour hand. Alte rnatively, you can set the 24-hour hand to display the time in a different time zone.

HOW TO SET THE TIME AND DATE, HOW TO USE THE TIME DIFFERENCE ADJUSTMENT FUNCTION

How to set the time

•

When setting the time, ensure that the watch is working: the second hand is

moving at one-second intervals.

•

In a case that the watch is completely stopped due to a shortage of stored elec-

trical energy, recharge the watch until the second hand resumes the normal one-second interval movement, and then reset the time and calendar. (Refer to "IF THE SECOND HAND STARTS MOVING AT TWO-SECOND INTERVALS" on page 28.)

•

The 24-hour hand can be used in two ways. Since the time setting procedure

differs according to the usage, please choose the method before setting the time.

<Me thod 1 > Simply using th e 24-hour hand to show

the 24-hour time as an AM/ PM indi cator.

• This is the standard usage for the 24-hour hand.

<Method 2> Using the 24-hour hand to indicate the time in a different time zone.

• For instance, by setting the 24-hour hand to

GMT while setting the hour and minute hands to indicate the time in your area, you can easily check GMT with the 24-hour hand at any time.

PRECAUTIONS ON USING THE COMPASS

USING 24-HOUR HAND TO INDICATE DIRECTIONS (ONLY FOR MODELS WITH THE ROTATING COMPASS bEzEL OR RING)

•

Please use the compass in places where the sun is visible or its location is known.

•

Before using the compass, it is necessary to set the 24-hour hand to the current time of

your area.

•

The compass is so designed to provide only a rough indication of directions, and

should not be used where accuracy is critical.

•

If daylight saving time (summer time) is in effect in your area, be sure to set your watch

one hour behind the current time before using the rotating compass.

How to use the compass bezel (ring)

1 Set "N (North)" on the rotating compass bezel (ring) to the 12 o’clock marker. The

direction marks on the bezel (ring) are set as follows; 3 o’clock position: E (East) 6 o’clock position: S (South) 9 o’clock position: W (West)

2 While keeping the dial level, point the 24-hour hand in the direction of the sun. The direction

marks indicate the corresponding directions.

[In the Northern Hemisphere]

[In the Southern Hemisphere]

1 Set "S (South)" on the rotating compass bezel (ring) to the 24-hour hand. 2 While keeping the dial level, point the 12 o’clock marker in the direction of the sun.

The direction marks indicate the corresponding directions.

IF THE SECOND HAND STARTS MOVING AT TWO-SECOND INTERVALS (ENERGY DEPLETION FOREWARNING FUNCTION)

When the seco nd hand s tar ts moving at two-second intervals whether it is worn or left un touched, the watch may run dow n within approx imately 24 hours.

In such a c ase, swing the watch f rom sid e to side to sufﬁciently charge the rechargeable battery (refer to "HOW TO CHARGE AND START T HE WATCH" on page 6 ), and t hen reset the time and c alendar.

INSTANT-START FUNCTION

When a long time has passed since the watch stopp ed, you c an get i t star ted

quick ly with only a few swing s.

The in stan t-start function will remain a ctive for approximately 3 years af ter a

fully-charged wa tch stops wor king.

Never install a silver oxide battery for conventional watches in place of the rechargeable battery. The battery may burst, become very hot or catch ﬁre.

CAUTION

REMARKS ON THE RECHARGEAbLE bATTERY

The elec tric energy genera ted while the watch is worn on your w rist is stored

in the rechargeable b attery. It is a power source c ompletely different f rom conven tional batteries for watches an d does not require any periodi c replacement.

W hen the r echargeable bat ter y. is fully charged, the watch will keep operating

for approximately 6 months without recharging the rechargeable battery.

The duration of charge decrease s gradually over time. The extent of de crea se,

however, varies depending on the environment and conditions of use.

The r echargea ble b at tery is a cle an an d environmenta lly f rie ndly power

sourc e.

* When this functio n is activated, the se cond hand wi ll start moving at two -sec ond interval s.

Swing the watch from si de to side to cha rge the rechargeabl e battery by referring to " NUMBER OF SWIN GS AND POW ER RESERVE" on pa ge 7.

* After th e second han d starts moving at on e-sec ond interval s, put the watch on you r wrist so that

it will be charg ed further.

* The w atch remains ac curate even while the se cond hand is m oving at two- second i ntervals.

NOTES FOR USING THE WATCH

HOW TO CHARGE AND START THE WATCH

To charge the rechargeable battery efﬁciently, swing the watch from side to side, 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.

When the watch has been left untouched for more than one year after it has completely stopped, the second hand may not start moving at normal one-second intervals even if the watch is swung the number of times indicated in "NUMBER OF SWINGS AND POWER RESERVE" on page 7. In this case, swing the watch further until the second hand starts moving at 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.

The watch is equipped with an instant-start function, and it may start operating after it is swung several times. For details, see "INSTANT-START FUNCTION".

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 when the watch is worn on your arm, it will not be charged if your arm is not in motion.

POWER RESERVE INDICATOR

The power reserve indicator provides only a general guideline of the duration within which the watch keeps operating without needing to be charged.

You can immediately press the button again to recheck the power reserve one more time. To do so a third time, however, wait until the second hand resumes normal movement before pressing the button again.

When the second hand moves at two-second intervals, the power reserve is very low and the indicator

does not function.

Immediately after the watch is swung to charge the rechargeable battery, the second hand may not properly indicate the power reserve. Please check again after 10 to 15 minutes have elapsed.

Precaution on see-through case-back models:

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 rechargeable battery. This condition, however, will be corrected when the case back is turned away from the light.

TIME/CALENDAR SETTING

To set the exact time, pull out the crown all the way when the second hand is at the 12 o'clock

position and push it back in to the normal position in accordance with a time signal.

When setting the hour hand, pull out the crown to the ﬁrst click, turn it to set the hour hand to the current hour, and then check that AM/PM is correctly set. The watch is designed so that the calendar changes once in 24 hours. Turn the hand past the 12 o'clock marker to determine whether the watch is set for the A.M. or

P.M. period. If the calendar changes, the time is set for the A.M. period. If the calendar does not change, the time is set for the P.M. period. Turn the crown slowly, checking that the hour hand moves at one-hour intervals.

When setting the minute hand, pull out the crown all the way to turn the minute hand. Advance the hand 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.

When setting the date, pull out the crown to the ﬁrst click and turn it to rotate the hour hand until the

date changes. The date advances one day by turning the hour hand two full rotations clockwise, while the date is set back one day by turning the hour hand two full rotations counterclockwise.
