TACHYMETER
(for models with tachymeter scale on the dial)
To measure the hourly average speed of a vehicle
1
2
Use the stopwatch to determine
how many seconds it takes to go
1 km or 1 mile.
Ex. 1
Second hand:
40 seconds
Tachymeter scale indicated by
Second hand gives the average
speed per hour.
Tachymeter scale: “90”
“90” (tachymeter scale figure) x 1 (km or mile)
= 90 km/h or mph
* 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
“90” (tachymeter scale figure) x 0.5 (km or mile) = 45 km/h or mph
18
To measure the hourly rate of operation
Ex. 1
1
2
Use the stopwatch to measure
the time required to complete 1
job.
Second hand:
20 seconds
Tachymeter scale indicated by
Second hand gives the average
number of jobs accomplished per
hour.
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
19
NECESSARY PROCEDURE AFTER BATTERY CHANGE
● When the battery is replaced, the information stored in the IC does not correspond
with the time and date actually displayed. Before using the watch, therefore, be sure
to reset the hands and date, following the procedure below.

* If the stopwatch is counting, first press Button B
to stop measurement and then press Button A to
reset the hands.

NOTES ON OPERATING THE WATCH
*1 When a hand is selected, it will move back and forth and return to where it was.
When the date is selected, it will advance one day and return to the current date.
*2 The hand(s)/date move(s) quickly if the corresponding button is kept pressed for 2
seconds.
*3 As Minute hand moves, Hour hand also moves correspondingly.
*4 When setting Hour hand, check that AM/PM is correctly set.
•
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.
*5 The alarm time can be set with the CROWN both at the normal position and at the
extended position.
*6 Alarm test: With the CROWN at “ALM.ON”, press and hold Buttons A and B at
the same time.
*7 Remarks on timer operation:
•
•
•
In TIMER mode, Hour hand stops at the 12 o’clock position.
With each press of the buttons, a beep sounds for confirmation.

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

BATTERY CHANGE
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.
2
Years
* 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.
24
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.

range of 5°C and 35°C (41°F
-10°C
and 95°F).
Temperatures over 60°C (140°F) or below
–10°C (+14°F) may cause a slight time loss
or gain or battery leakage or shorten the
battery life.
However, the above conditions will be
corrected when the watch returns to normal
temperature.
* Do not operate the crown or push the buttons
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.
