While loss/gain of a quartz watch is indicated by a monthly or annual rate,  
accuracy of a mechanical watch is normally indicated by a daily rate (loss/gain  
per day).  
Normal usage accuracy of a mechanical watch varies according to conditions of  
use (time period that the watch is worn on the wrist, temperature environment,  
hand movement, and winding state of the mainspring).  
When the watch is affected by strong magnetism, it temporarily gains or loses  
time. If the watch encounters a strong magnetic field, the parts of the watch may  
be magnetized. In this case, repairs such as removal of magnetism are required.  
Contact the retailer from whom the watch was purchased.

HOW TO USE  
This watch is an automatic watch equipped with a manual winding mechanism.  
When the watch is worn on the wrist, the motion of the wearer's arm winds the  
mainspring of the watch.  
The crown  
turns.  
If your watch is completely stopped, it is recommended that you manually wind

"HOW TO  
USE"  
How to manually wind the mainspring by turning the crown  
To set the watch  
Unscrew the crown by turning it  
counterclockwise.  
The crown  
does not  
turn.  
1. Slowly turn the crown clockwise (in  
the 12 o’clock direction) to wind the  
mainspring.  
Unscrew.  
*
Turning the crown counterclockwise (the  
6 o’clock direction) does not wind the  
mainspring.  
Screw up.  
2. Continue to turn the crown until the  
mainspring is sufficiently wound. The small  
second hand will start moving.  
*
If your watch has a screw-lock crown, the crown will screw into the watch case  
for added protection.  
After completing all settings of the watch, screw the crown in again by turning it  
clockwise while pressing it.  
If the crown is too stiff to be screwed in, turn the crown counterclockwise once and  
then give another try.  
Do not screw it in by force as it may damage the slots of the crown.  
3. Set the time and date before putting the  
watch on your wrist.

HOW TO SET THE TIME AND DATE  
*
*
There is no need to turn the crown further when the mainspring is fully wound. But  
the crown can be turned without damaging the watch mechanism.  
Once the watch is wound up fully, it operates for about 50 hours. However, when  
the stopwatch is used continuously for a certain period, the watch may not operate  
for as long as 50 hours.  
Check that the watch is operating, and then set the time and date.  
The watch is provided with a date function and is designed so that the date  
changes once every 24 hours. The date changes around 12 o’clock midnight. If  
AM/PM is not properly set, the date will change around 12 o’clock noon.  
*
*
If the watch is used without being wound up fully, gain or loss of the watch may  
result. To avoid this, wear the watch for more than 8 hours a day. If the watch is used  
without being worn on the wrist (if it is used on the desk like a clock, for example),  
make sure to wind it up fully every day at a fixed time.  
If the watch has stopped with the mainspring unwound, winding the mainspring  
with the crown will not start the watch immediately. This is because the mainspring  
torque (force) is low at the beginning of its winding due to the characteristics of  
mechanical watches. The small second hand starts to move when a certain degree  
of strong torque is reached after the mainspring has been wound up. However,  
swinging the watch from side to side to forcibly turn the balance can start the watch  
sooner.  
1. Pull out the crown to the first click. (The  
small second hand continues moving and  
the accuracy of the watch is unimpaired.)  
2. The date can be set by turning the crown  
clockwise. Turn it until the previous day’s  
date appears.  
Ex.)If today is the 6th of the month, first set  
the date to ”5” by turning the crown  
clockwise.  
CAUTION  
Do not set the date between 8:00 p.m. and 2:00 a.m. If you do so, the date  
may not change properly on the following day or malfunction of the watch  
may occur.

3. Pull out the crown to the second click when the small second hand is at the 12  
o’clock position. (The small second hand stops on the spot.)  
Date adjustment at the beginning of the month  
It is necessary to adjust the date on the first day after a month that has less than  
31 days.  
Turn the crown to advance the hands until the date changes to the next. The time  
is now set for the a.m. period. Advance the hands to set the correct time.  
4. Push the crown back in to the normal position in accordance with a time  
signal.  
Ex.) To adust the date in the a.m. period  
on the first day of a month following a  
30-day month.  
1. The watch displays “31” instead of "1".  
Pull out the crown to the first click.  
2. Turn the crown to set the date to “1”  
and then push the crown back in to the  
normal position.

CAUTION  
CAUTION  
The mechanism of mechanical watches is different from that of quartz  
watches.  
Do not set the date between 8:00 p.m. and 2:00 a.m. If you do so, the  
date may not change properly on the following day or malfunction of the  
watch may occur.  
When setting the time, make sure to turn back the minute hand a little  
behind the desired time and then advance it to the exact time.

TO MEASURE THE HOURLY RATE OF OPERATION  
Ex. 1

Use the stopwatch to measure  
the time required to complete  
1 job.  
The telemeter can provide a rough indication of the distance to the source of  
light and sound.  
STOPWATCH  
second hand:  
20 seconds  
The telemeter indicates the distance from your location to an object that emits  
both light and sound. For example, it can indicate the distance to the place  
where lightning struck by measuring the time elapsed after you see a flash of  
lightning until you hear the sound.  
A flash of lightning reaches you almost immediately while the sound travels to  
you at a speed of 0.33 km/second. The distance to the source of the light and  
sound can be calculated on the basis of this difference.

Tachymeter scale indicated by  
the STOPWATCH second hand  
gives the average number of  
jobs accomplished per hour.  
The telemeter scale is graduated so that the sound travels at a speed of 1 km in  
Tachymeter scale: "180"  
3 seconds.*  
“180” (tachymeter scale figure) x 1 job  
= 180 jobs/hour  
*Under the condition of temperature of 20 °C(68 °F.)  
Ex. 2: If 15 jobs are completed in 20 seconds:  
CAUTION  
"180" (tachymeter scale figure) x 15 jobs = 2700 jobs/hour  
The telemeter provides only a rough indication of the distance to the place  
where lightning struck, and therefore, the indication cannot be used as the  
guideline to avoid the danger of lightning. It should also be noted that the  
speed of the sound differs depending on the temperature of the atmosphere  
where it travels.

When the mainspring is fully wound, the crown can be turned further, or the  
mainspring may wind without damaging the mainspring itself. The mainspring  
of the watch employs a slipping mechanism, an automatic watch specific  
mechanism, to prevent the mainspring from overwinding.  
TO PRESERVE THE QUALITY OF YOUR WATCH  
CAUTION  
Remarks on the automatic mechanism of the mainspring  
CARE OF YOUR WATCH  
The mainspring of the watch becomes fully wound when it is worn for twelve  
hours for three to five consecutive days. However, the winding state of the  
mainspring may vary depending on actual use conditions, such as the number  
of hours you wear the watch or the extent of your movement while wearing it. It  
is recommended that you observe the power reserve indicator to check the level  
of remaining power of your watch.  
The case and band touch the skin directly. Keep the case and band clean  
at all times. This will help to extend the life of the watch and will reduce  
the risk of skin irritations.  
When you take the watch off, wipe off moisture, sweat or soil with a soft  
dry cloth as soon as possible. This will help to extend the life of the case,  
band and gasket.  
*
In a case where you wear the watch for a short period of time each day, observe  
the power reserve indicator to check the level of the remaining power. If  
necessary, manually wind the mainspring.  
<Leather strap>  
Gently blot up the moisture using a soft dry cloth. Do not rub the leather,  
as this may cause abrasions or discoloration.  
<Metal bracelet>  
To keep the bracelet clean, use a soft toothbrush dipped in clean or soapy  
water. Be careful not to get water on the case.

LUMIBRITETM  
*
Whentakingashowerwhilewearingawaterresistant5barwatch, ortaking  
a bath while wearing a water resistant 10, 15 or 20 bar watch, make sure to  
observe the following:  
LumiBrite is a luminous paint that is completely harmless to human beings and the natural  
environment, containing no noxious materials such as radioactive substances.  
LumiBrite is a newly-developed luminous paint that absorbs the light energy of sunlight or  
artificial light in a short time and stores it to emit light in the dark.  
For example, if exposed to a light of more than 500 lux for approximately 10 minutes,  
LumiBrite can emit light for 5 to 8 hours.  
Please note, however, that, as LumiBrite emits the light it stores, the luminance level of the  
light decreases gradually over time. The duration of the emitted light may also differ slightly  
depending on such factors as the brightness of the place where the watch is exposed to light  
and the distance from the light source to the watch.  
When you make a dive in dark water, LumiBrite may not emit light unless it has absorbed and  
stored light sufficiently.  
• Do not operate the crown when the watch is wet with soapy water or  
shampoo.  
• If the watch is left in warm water, a slight time loss or gain may be caused.  
This condition, however, will be corrected when the watch returns to  
normal temperature.  
NOTE:  
Pressureinbarisatestpressureandshouldnotbeconsideredascorresponding  
to an actual diving depth since swimming movements tend to increase the  
pressure at a given depth. Care should also be taken when diving with the  
watch into water.  
Before diving, therefore, be sure to expose the watch to light under the conditions specified  
above, so that it fully absorbs and stores light energy. Otherwise, use the watch together with  
an underwater flashlight.

temperatures for a long time. temperature.  
The accuracy of mechanical watches may not fall within the specified range of  
time accuracy because of loss/gain changes due to the conditions of use, such as  
the length of time during which the watch is worn on the wrist, arm movement,  
whether the mainspring is wound up fully or not, etc.  
The key components in mechanical watches are made of metals which expand  
or contract depending on temperatures due to metal properties. This exerts an  
effect on the accuracy of the watches. Mechanical watches tend to lose time at  
high temperatures while they tend to gain time at low temperatures.  
In order to improve accuracy, it is important to regularly supply energy to the  
balance that controls the speed of the gears. The driving force of the mainspring  
that powers mechanical watches varies between when it is fully wound and  
immediately before it is unwound. As the mainspring unwinds, the force  
weakens.  
Relatively steady accuracy can be obtained by wearing the watch on the wrist  
frequently for the self-winding type and winding up the mainspring fully everyday  
at a fixed time to move it regularly for the wind-up mechanical type.
