TACHYMETER
(for models with tachymeter scale on the dial)
●Tachymeter 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.
1
Tachymeter scale indicated by
STOPWATCH second hand gives
the average speed per hour.
2
Ex. 1
STOPWATCH
second hand:
40 seconds
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 STOPWATCH 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

13
English
To measure the hourly rate of operation
Use the stopwatch to measure
the time required to complete 1
job.
1
Tachymeter scale indicated by
STOPWATCH second hand gives
the average number of jobs ac-
complished per hour.
2
Ex. 1
STOPWATCH
second hand:
20 seconds
Tachymeter scale: “180”
“180” (tachymeter scale figure) x 1 job
= 180 jobs/hour
Ex. 2: If 15 jobs are completed in 20 seconds:
“180” (tachymeter scale figure) x 15 jobs = 2700 jobs/hour

BATTERY CHANGE
The miniature battery which powers your watch should last approximately
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.
5
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 small second hand moves at two-second intervals
instead of normal 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.

15
English
●Do not remove the battery from the watch.
●If it is necessary to take out the battery, keep it out of the reach of children. If
a child swallows it, consult a doctor immediately.
WARNING
●Never short-circuit, heat or otherwise tamper with the battery, and never
expose it to fire. The battery may burst, become very hot or catch fire.
●The battery is not rechargeable. Never attempt to recharge it, as this may cause
battery leakage or damage to the battery.
CAUTION

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.
START
(Flash of light)
STOP
(Crash of thunder)
Press button A to start the
stopwatch as soon as you
see the light.
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.
