TACHYMETER
(for models with tachymeter scale on the dial)

English

To measure the hourly average speed of a vehicle

1

Use the stopwatch to determine
how many seconds it takes to go
1 km or 1 mile.

2

Tachymeter scale indicated by
Second hand gives the average
speed per hour.

* Tachymeter scale can be used only when the time required is less than 60 seconds.

Ex. 2: If the measuring distance is extended to 2 km or miles or shortened to 0.5 km or miles

and Second hand indicates “90” on tachymeter scale:

“90” (tachymeter scale figure) x 2 (km or mile) = 180 km/h or mph

18

“90” (tachymeter scale figure) x 0.5 (km or mile) = 45 km/h or mph

Ex. 1Ex. 1

Second hand:

40 seconds

Tachymeter scale: “90”

“90” (tachymeter scale figure) x 1 (km or mile)
= 90 km/h or mph

To measure the hourly rate of operation

English

Use the stopwatch to measure

1

Ex. 1Ex. 1

the time required to complete 1
job.

2

Tachymeter scale indicated by
Second hand gives the average
number of jobs accomplished per
hour.

“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

Second hand:
20 seconds

Tachymeter scale:
“180”

• Press Button A to turn Hour hand past the 12 o’clock marker to determine whether the watch

is set for the A.M. or P.M. period. If the date changes, the time is set for the A.M. period. If
the date does not change, the time is set for the P.M. period.
While the date is changing, Hour hand stops on the 12 o’clock position even if Button A is kept
pressed.

BATTERY LIFE INDICATOR

● The battery needs to be replaced when you see the Second hand moving at two-second

intervals instead of normal one-second intervals.

English

* The watch will, however, remain accurate while Second hand is moving at two-second

intervals.

BATTERY CHANGE

2

Years

24

The miniature battery which powers your watch should last approximately
2 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 SR927W battery.

* The battery life may be less than 2 years if:

•

the alarm is used more than once a day,

•

the timer is used for more than 5 minutes a day, and/or

•

the stopwatch is used for more than 5 minutes a day.

WARNING

● 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.

● Never short-circuit, tamper with or heat the battery, and never expose it to

fire. The battery may burst, become very hot or catch fire.

CAUTION

● The battery is not rechargeable. Never attempt to recharge it, as this may

cause battery leakage or damage to the battery.
