3. When setting the hour hand, be sure to check that AM/PM is correctly set. The watch is so designed
that the date changes once in 24 hours.
4. When setting the minute hand, first advance it 4 to 5 minutes ahead of the desired time and then turn
it back to the exact minute.

TACHYMETER
(for m odels w ith tachym eter scale on the dial)
To m easure the hourly average speed of a vehicle
Ex. 1
1
Use the stopwatch to determ ine
how m any seconds it takes to go
1 km or 1 m ile.
STOPWATCH
second hand:
40 seconds
2
Tachym eter scale indicated by
STOPWATCH second hand gives
the average speed per hour.
Tachymeter scale: “90”
“90” (ta c hym e te r sc a le fig ure ) x 1 (km or m ile )
= 90 km / h or m p h
● Tachym eter scale can be used only when the tim e required is less than 60 seconds.
Ex. 2: If the m e a suring dista nc e is e xte nde d to 2 km or m ile s or shorte ne d to 0.5 km or m ile s
a nd STOPWATCH se c ond ha nd ind ic a te s “90” on ta c hym e te r sc a le :
“90” (tachym eter scale figure) x 2 (km or m ile) = 180 km /h or m ph
“90” (tachym eter scale figure) x 0.5 (km or m ile) = 45 km /h or m ph
12
To m easure the hourly rate of operation
Ex. 1
1
Use the stopwatch to m easure
the tim e required to com plete 1
job.
STOPWATCH
second hand:
20 seconds
2
Tachym eter scale indicated by
STOPWATCH second hand gives
the average num ber of jobs ac-
com plished per hour.
Tachymeter scale: “180”
“180” (ta c hym e te r sc a le fig ure ) x 1 job
= 180 job s/ hour
Ex. 2: If 15 job s a re c om p le te d in 20 se c ond s:
“180” (tachym eter scale figure) x 15 jobs = 2700 jobs/hour

BATTERY CHANGE
The miniature battery which powers your watch should last approximately
5
5 years. However, because the battery is inserted at the factory to check
the function and performance of the watch, its actual life once in your
possession may be less than the specified period. When the battery expires,
be sure to replace it as soon as possible to prevent any malfunction. For
battery replacement, we recommend that you contact an AUTHORIZED
SEIKO DEALER and request SEIKO SR927SW battery.
Years
* If the stopwatch is used for more than 2 hours a day, the battery life may be less than
the specified period.
* After the battery is replaced with a new one, set the time/calendar and adjust the
stopwatch hand position.
● Battery life indicator
When the battery nears its end, the sm all second hand m oves at two-second intervals
instead of norm al one-second intervals. In that case, have the battery replaced with a new
one as soon as possible.
* The watch remains accurate while the small second hand is moving at two-second intervals.
14
WARNING
● Do not rem ove the battery from the w atch.
● If it is necessary to take out the battery, keep it out of the reach of children. If
a child sw allow s it, consult a doctor im m ediately.
CAUTION
● Never short-circuit, heat or otherw ise tam per w ith the battery, and never
expose it to fire. The battery m ay burst, becom e very hot or catch fire.
● The battery is not rechargeable. Never attem pt to recharge it, as this m ay cause
battery leakage or dam age to the battery.

TELEMETER
(for models with telemeter scale on the dial)
● The telemeter can provide a rough indication of the distance to the source of light
and sound.
● 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.
● The telemeter scale is so graduated that the sound travels at a speed of 1 km in 3
seconds.*
*Under the condition of temperature of 20°C(68°F).
CAUTION
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.
A
START
(Flash of light)
1
Press button A to start the
stopwatch as soon as you
see the light.
STOP
(Crash of thunder)
2
3
When you hear the sound,
press button A to stop the
stopwatch.
Read the telemeter scale
that the stopwatch second
hand points to.
Approx. 3 km
Please note that the stopwatch second hand moves in 1/5 second increments and does not
always point exactly to the graduations of the telemeter scale. The telemeter scale can be used
only when the measured time is less than 60 seconds.
