� FEATURESThis watch is a multi-hands analog solar watch withalarm and chronograph functions, and a solar powerfunction as its base which provides the powersource for the watch’s hands movement and alarmsound by converting solar energy into electricalpower with the solar cell fitted on its face.

� BEFORE USINGA secondary battery is used in this watch to storeelectrical energy. This secondary battery is aclean energy battery which does not use anytoxic substances such as mercury. Once fullycharged, the watch will continue to run for about80 days (using the alarm sound for 15 seconds/dayand the chronograph timer for 60 minutes/day)without further charging.

How to use this watch properlyFor the comfortable use of this watch and itsadditional alarm and chronograph functions, takecare to keep it sufficiently recharged.

There is concern of overcharging this watch.(Overcharging Prevention Feature is included)We recommend that you recharge the watchevery day.

Please refer to the diagram on the left whenreading this instruction manual.

Before usingWhen the watch does not operate according tothe instruction manual, it is insufficientlycharged.Charge the secondary battery of the watch formore than 6 hours, approximately 20cm (8in.)away from the fluorescent or incandescent lamp(30W) as light sources.When charging thesecondary battery, do not put it too close to thelight source.* When charging the watch under direct rays

of the sun, charge for more than an hour.

IMPORTANT

� FUNCTIONS OF SOLAR POWERED WATCHThese functions are only found in the solar powerwatch. If the watch becomes insufficiently charged,a warning comes into operation and the displaychanges, as below.

Insufficient Charge Warning FunctionIf the watch is put in the undercharged state duringany display mode, it switches to the time displaywhen in the other display modes, then the secondhand moves to the � CHARGE position, indicatingthe shortage of electricity. (Electric power shortagewarning display) Even then, the time (hour, minuteand 24-hour hands) runs accurately.* The alarm does not ring even if it is set.* If the chronograph is being used, measurement

stops and it is reset.* The push button does not function.

Refer to, “� In These Cases”.

Stop Warning FunctionIf the watch is left intact in the undercharged state,about 5 days later the second hand will move to the� STOP position, indicating that the watch hasstopped due to electric power shortage. (Stopwarning display) The other hands (hour, minute and24-hands) also stop.* In this condition, all functions stop.

Refer to, “� In These Cases”.

Time Setting Warning FunctionWhen the watch is recharged by exposing it to lightafter once stopped, the second hand moves to the� SET position, indicating that the watch does notkeep correct time. (Time setting warning display)* The hour, minute and 24-hour hands run at the

incorrect time.Refer to, “� In These Cases”.

Overcharge Prevention FunctionYou can recharge without worry.When the secondary battery is fully recharged, theovercharging prevention function works so that thesecondary battery is not overcharged.

� NOTES ON USEPlease take care to charge your watch during use.Please note that if you wear long sleeves, the watchcan easily become insufficiently charged because itis hidden and not exposed to light.• When you take off the watch, try to place it in as

bright a place as possible, and it will alwayscontinue to run properly.

CAUTIONNever use another battery apart from the secondarybattery (Titanium Lithium Ion Battery) used in thiswatch.The watch structure is so designed that a differentkind of battery other than that specified cannot beused to operate it. However, in case a differentbattery such as a silver battery is used by somechance, there is a danger that it will be overchargedto burst, causing damage to the watch and even thehuman body.When you replace the secondary battery, be sure touse a designated secondary battery.

NOTES ON CHARGING• The watch will be damaged during recharging if it

gets too hot (over about 60�C/140�F). Avoidrecharging at high temperatures.(eg) Charging the watch near a light source that

easily becomes hot, such as an incandescentlamp or a halogen lamp.Charging in a place that easily becomes hotsuch as a dashboard.

• Note that full charging is difficult in a placeirradiated by only weak light.

• When you charge the watch by an incandescentlamp, take a distance about 50cm (20in.) from thelight source to prevent extremely high temperature.

� NAMES OF PARTSPlease see the watch illustration at the beginning.

* The hour, minute and 24-hour hands show thepresent time.

2. Each time button �A is pressed, it repeatedlystarts or stops the chronograph, along with aconfirmation sound.

How to read each chronograph hand if themeasured time when the chronograph is stopped isover 1 minute.➀ Read the number of minutes with the function

hand➁ Read the number of seconds with the second

hand.➂ While pressing button �B continuously, the function

hand switches to 1/20 (0.05) second handmeasurement, so read the value at that time.When button �B is released, the function handresumes showing chronograph minutes.

3. While the chronograph is stopped state, pressingbutton �C resets the function hand and thesecond hand to the 0 position.

Chronograph Split MeasurementPressing button �C during chronographmeasurement causes the chronograph split time toappear on display with a beep for confirmation.Press button �C again, the next chronograph splittime is displayed, along with a confirmation sound.The split time display is automatically cancelledafter about 10 seconds, and the chronographreturns to the measurement state.During either chronograph split time display ormeasurement, pressing button �A causes thechronograph stop to appear on display.In the chronograph stop state, pressing button �Ccauses the chronograph reset.

* During split timemeasurement or whilesplit time display, eachtime you press button �Cthe next split time isdisplayed.

� IN THESE CASESWhen shown the Insufficient Charge WarningDisplay

If the watch is put in the underchargedstate during any display mode, itswitches to the time display when inother display modes, then the secondhand moves to the � CHARGEposition, indicating insufficientlycharged.

In such a case, expose the watch to sufficient lightfor the warning state to be cancelled. (The secondhand returns to 1 second movement)It takes about 30 minutes to complete charging;from starting to expose the watch to light until thiswarning state is cancelled. The charging time variesdepending on the light (light source) that radiatesover the watch.

When Shown the Stop Warning DisplayIf the watch is left intact in theundercharged state, about 5 dayslater the second hand will move tothe � STOP position, indicating thatthe watch has stopped due toinsufficient recharge.

* All functions are stopped in this state.In such a case, expose the watch to sufficient lightfor the warning state to be cancelled.After carrying out sufficient charging, it is necessaryto reset the alarm time.

When Shown the Time Setting Warning DisplayIf you expose a watch which hasstopped once to light and recharge it,the second hand will move to the �SET position to let you know that thetime is incorrect.In such a case, readjust the hour,minute and 24-hour hands to keepthe correct time.

Without adjusting the time hands after the watch isfully recharged, you cannot use such functions asalarm, chronograph, etc. properly.* Be careful because if the watch is not sufficiently

charged during the Time Setting Warning Displaystate, and if light is blocked from it, the secondhand will change to the � STOP position and thewatch will stop running.

� CHECKING AND ADJUSTING EACH HAND’S“0” POSITION

The watch’s display may go wrong due to the effectof static electricity, strong shock, etc.In such a case, check and adjust the “0” postion ofeach of the following hands.

“0” Position Checking1. Press button �M to set the

mode hand at <CHR> positionfor chronograph function.

2. Pull out button �M by one clickand check to see if each hour,minute, second, 24-hour andfunction hands quickly moves

to “0” position (12 o’clock position) while datehand quickly moves to “1” position.If any hand returns wrong out of the correctposition “0” or “1”, the watch needs [“0” positionadjustment].

“0” Position Adjustment1. For adjusting the second hand

to “0” postion:• Press button �A .2. For adjusting hour, minute and

24-hour hands to “0” position:• Press button �C .3. For adjusting date and function

hand to position “1” and “0” respectively:• Press button �B .• “0” position for function hand is equivalent to

12 o’clock position just after the date has beenset at “1” position.

• With four turns of a function hand, date indicationis adjusted by a day.

• If button �A , �C or �B is continuously pressed, thehand corresponding to the button moves quickly.

4. When “0” position adjustment is complete, pushbutton �M into the original position.

* Make sure to reset time, calendar, alarm timecorrectly following “0” position adjustment.

� PRECAUTIONS1. Resistance to waterCheck the chart to determine the water resistantproperties of this watch.

2. Avoid temperature extremesAvoid leaving your watch in extremely warm or coldlocations for long periods of time.• This may cause your watch to gain or lose time and

affect its other function.• The watch restores its original accuracy if it is placed

in normal temperature.

3. Avoid strong shockThis watch will withstand the bumps and jarsnormally incurred while playing and during sportsactivities.Avoid dropping your watch on the ground orsubjecting the watch to severe shock which maycause malfunction or damage.

4. Avoid strong magnetic fieldsKeep your watch out of the immediate vicinity ofstrong magnets. Generally, your watch is notaffected by magnetic fields from such householdappliances as television sets and stereo equipment.

5. Static electricityThe integrated circuits used in the watch aresensitive to static electricity. If exposed to intensestatic electricity, the watch’s display may lose itsaccuracy.

6. Avoid harmful chemicals, solvents and gasesAvoid wearing your watch in the presence of strongchemicals, solvents and gases. If your watch comesin contact with materials such as gasoline, benzine,paint thinner, alcohol, spray cosmetics, nail polish,nail polish remover, adhesives or paint,discolouration, deterioration or damage to the case,band, and other components may occur.

7. Keep your watch cleanIt may become difficult to pull out the crown due todirt and dust getting caught between the crown andthe watch case when the watch is worn for longperiods of time. To help prevent this from happening,turn the crown freely back and forth occasionallywhile it is in the normal set position.Wipe off any water and moisture that adheres to thecase, glass and band with a soft, clean cloth. Any dirtleft on the case or band may cause skin rash.A watchband will easily become soiled with dust andperspiration because it is in direct contact with theskin. Even a stainless or gold-plated band may beginto corrode if it has not been cleaned for a long period of time.Mesh bands, because the meshes are very fine, willlose their particular “flexibility” if they are left soiledfor a long time.Metal watch bands should be washed periodically tokeep them looking beautiful at all times.Metal watchbands are usually washed with a brushin mild, soapy water and well wiped with a soft,absorbent cloth to make sure all water is removed.Pay attention to prevent any water from gettinginside your watch when the band is washed.

8. Periodic inspectionGetting your watch checked once in two or threeyears is recommended to ensure long use andtrouble-free operation.
