lWhen the energy stored in the rechargeable battery is reduced to an extremely
low level, the second hand starts moving at 2-second intervals instead of the
normal 1-second intervals. The watch remains accurate even while the second
hand is moving at 2-second intervals.

NOTE ON POWER SUPPLY
l The battery used in this watch is a rechargeable battery, which is different
from ordinary silver oxide batteries. Unlike other disposable batteries such as
dry-cell batteries or button cells, this rechargeable battery can be used over
and over again by repeating the cycles of discharging and recharging.
l The capacity or recharging efficiency of the rechargeable ba ttery may
gradually deteriorate for various reasons such as long-term use or usage
conditions. Worn or contaminated mechanical parts or degraded oils may
also shorten recharging cycles. If the efficiency of the rechargeable battery
decreases, it will be necessary to have the watch repaired.
lDo not remove the rechargeable battery yourself. Replacement of the
rechargeable battery requires professional knowledge and skill. Please
ask a watch retailer for replacement of the rechargeable battery.
lInstallation of an ordinary silver oxide battery can generate heat that can
cause bursting and ignition.
CAUTION
vTO PREVENT THE ENERGY DEPLETION
•When wearing the watch, make sure that the watch is not covered by
clothing.
•When the watch is not in use, leave it in a bright place as long as
possible.

TACHYMETER
(for models with tachymeter scale on the dial)
lTachymeter scale can be used only when the time required is less than 60 seconds.
TO MEASURE THE HOURLY AVERAGE SPEED OF A VEHICLE
Use the stopwatch to determine
how many seconds it takes to
go 1 km or 1 mile.
Tachymeter scale indicated by
the STOPWATCH 1/5-second
hand gives the average speed
per hour.
Ex. 1
STOPWATCH 1/5-
secondhand:

Tachymeterscale:"90"
“90” (tachymeter scale figure) x 1 (km or mile)
= 90 km/h or mph
Ex. 2: If the measuring distance is extended to 2 km or miles or shortened to 0.5 km or
miles and the STOPWATCH 1/5-second hand indicates “90” on tachymeter scale:
"90" (tachymeter scale figure) x 2 (km or mile) = 180 km/h or mph
"90" (tachymeter scale figure) x 0.5 (km or mile) = 45 km/h or mph
TO MEASURE THE HOURLY RATE OF OPERATION
Use the stopwatch to measure
the time required to complete
1 job.
1
Tachymeter scale indicated by

TELEMETER
(for models with telemeter scale on the dial)
l The telemeter can provide a rough indication of the distance to the source of
light and sound.
l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.
l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.
lThe telemeter scale is graduated so that the sound travels at a speed of 1 km in
3 seconds.*
*Undertheconditionoftemperatureof20° C(68° F)
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.
HOW TO USE THE TELEMETER
Before beginning, check that the stopwatch has been reset.
START
(Flash of light)
STOP
(Crash of thunder)
Press Button A to start the
stopwatch as soon as you
see light.
When you hear the sound,
press Button A to stop the

Solutions
If you often encounter this problem even though you wear the watch everyday, the
watch may not be exposed to sufficient light while you wear it. For example, the
watch may be covered by the cuff of clothing. Re
charge the watch sufficiently by
exposing it to light.
The time required for charging will vary depending on the intensity of light.
Recharge the watch referring to "GUIDELINE OF CHARGING TIME/ACCURACY."
Reset the watch by following the instructions in “IMPROPER FUNCTION."
Return the watch to a normal temperature so that it works accurately as usual, and
then reset the time. The watch has been adjusted so that it works accurately when
it is worn on your wrist under a normal temperature range between 5 ºC and 35 ºC.
Correct this condition by moving and keeping the watch away from the
magnetic source. If this action does not correct the condition, contact the
retailer from whom the watch was purchased.
Reset the time. If the watch does not return to its normal accuracy after
resetting the time, contact the retailer from whom the watch was purchased.

Troubles Possible causes
The STOPWATCH hands do not
return to the "0" position when the
stopwatch is reset.
Affected by external sources, or because the
internal IC had been reset, the stopwatch hand
positions have moved out of correct alignments.
Although the alarm time has not
been set, the time on the alarm
sub dial and the time on the main
dial are not the same.
The watch has been left close to an object
with a strong magnetic field. The watch has
been exposed to strong vibrations.
The inner surface of the glass is
clouded.
Moisture has entered the watch because the
gasket has deteriorated.
The date changes during the day. The time is set 12 hours ahead of or behind
the correct time.
Solutions
Adjust the STOPWATCH hands to the "0" position by following the instructions in
“SETTING THE TIME AND ADJUSTING STOPWATCH HAND POSITION”
Reset the time for main dial and alarm sub dial.
Contact the retailer from whom the watch was purchased.
Reset the time correctly, referring to “SETTING THE TIME AND ADJUSTING
STOPWATCH HAND POSITION”
