HOW TO USE THE TACHYMETER
(for models with tachymeter scale on the dial)
English
To measure the hourly average speed of a vehicle
Use the stopwatch to determine
1
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. If necessary,
22
shorten the measuring distance.
Ex. 1Ex. 1
Tachymeter
scale: “80”
“80” (tachymeter scale figure) x 1 (km or mile)
= 80 km/h or mph
➚
Second hand:
45 seconds
Page 23
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 “80” on tachymeter scale:
“80” (tachymeter scale figure) x 2 (km or mile) = 160 km/h or mph
“80” (tachymeter scale figure) x 0.5 (km or mile) = 40 km/h or mph
To measure the hourly rate of operation
English
Use the stopwatch to measure
1
the time required to complete 1
job.
2
Tachymeter scale indicated by
Second hand gives the average
number of jobs accomplished per
hour.
Ex. 2: If 15 jobs are completed
in 12 seconds:
“300” (tachymeter scale figure) x 15 jobs
= 4500 jobs/hour
Ex. 1Ex. 1
Second hand:
12 seconds
“300” (tachymeter
scale figure) x 1 job
= 300 jobs/hour

NOTES ON OPERATING THE WATCH
*1 • The day of the week is automatically set once the year, month and date are set.
English
24
• When the time is set in the 24-hour indication, the world time and alarm time will
also be displayed in the 24-hour indication.
*2
• The digits except seconds and “12H”/“24H” move quickly if Button D is kept
pressed.
• When the seconds read any number from “30” to “59” and Button D is pressed,
1 minute is added.
• When setting the hour digits in the 12-hour indication, check that the AM/PM
mark is properly set. In the 24-hour indication, there is no mark.
*3 The hands move counterclockwise by pressing Button A and clockwise by
pressing Button D. They move quickly if the respective buttons are kept pressed.
*4 If the watch is left untouched in TIME/CALENDAR SETTING display with the digits
flashing, it will automatically return to TIME/CALENDAR mode in 2 to 3 minutes.
*5 The hourly time signal will not ring while the alarm is ringing.
*6
• Daylight saving time is a system adopted by some countries to make the best
use of daylight during a certain period in summer. Under this system the time
is advanced an hour.
• The data on daylight saving time built into the watch’s memory was collected as
of February 1995, and use of daylight saving time may change when so decided
by the countries concerned. In that case, therefore, the watch may not show
daylight saving time properly.
Page 25
*7 The time differences and use of daylight saving time may change in some areas
or countries when they are so decided by the countries concerned. In that case,
therefore, the watch may not show time differences/daylight saving time properly.
*8
• The digits move quickly if Button D is kept pressed.
• When the time in TIME/CALENDAR mode is set in the 24-hour indication, the
alarm time will also be displayed in the 24-hour indication.
• When setting the hour digits in the 12-hour indication, check that the AM/PM
mark is correctly set.
*9 If the watch is left untouched in ALARM SETTING display with the digits flashing,
it will automatically return to ALARM mode in 2 to 3 minutes.
• The alarm mark is displayed if either of the alarms is engaged.
*10
• Alarm test : Press and hold Buttons C and D at the same time in TIME/
CALENDAR mode.
*11 Remarks on stopwatch function:
• After 100 hours have been measured, the stopwatch will automatically be reset
to “0:00'00"000”.
• Even while the stopwatch is counting, the display can be changed from
STOPWATCH to another by pressing Button A.
* The mode indicator for STOPWATCH mode flashes to indicate that the stopwatch is
counting. After the stopwatch is used, however, be sure to stop it by pressing Button C
as this will help to preserve the battery life.
• When the hourly time signal mark is displayed, a beep sounds with each press
of the buttons.

BATTERY LIFE INDICATOR
● When the words “BATTERY CHANGE” scroll in the scroll
window, replace the battery with a new one as soon as possible.
Otherwise, the watch will stop operating in 2 to 3 days. We
suggest that you have the battery replaced by a SEIKO DEALER.
* Even after the “BATTERY CHANGE” message appears, time accuracy
is not affected.
BATTERY CHANGE
2
Years
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 SR1130W battery.
* The battery life may be less than 2 years if:
•
the alarm is used more than 20 seconds a day,
•
the stopwatch is used for more than 3 minutes a day,
•
city selection is made more than 5 times a day,
•
the confirmation sound is used more than 10 times a day, and/or
•
the time transfer function is used more than once 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.
