TACHYMETER
[for models with tachymeter scale on the dial]
To measure the hourly average speed of a vehicle
Ex. 1
Tachymeter
scale: “90”
CHRONOGRAPH
second hand:
40 seconds
“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 CHRONOGRAPH second hand indicates “90” on
1 Use the stopwatch to determine
how many seconds it takes to go
1 km or 1 mile.
▲
2 Locate the second marker on the
main dial that corresponds to the
measured seconds, and the
tachymeter scale it indicates gives
the average speed per hour.
English
7
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
To measure the hourly rate of operation
Ex. 1
Tachymeter
English
“180” (tachymeter scale figure) x
1 job = 180 jobs/hour
Ex. 2: If 15 jobs are completed in 20 seconds:
8
“180” (tachymeter scale figure) x 15 jobs = 2700 jobs/hour
scale: “180”
CHRONOGRAPH
second hand:
20 seconds
1 Use the stopwatch to measure the
time required to complete 1 job.
▲
2 Locate the second marker on the
main dial that corresponds to the
measured seconds, and the
tachymeter scale it indicates gives
the average number of jobs
accomplished per hour.
NOTES ON OPERATING THE WATCH
ADJUSTING CHRONOGRAPH HAND POSITION
● The “0” position of the CHRONOGRAPH 1/10-second hand differs depending on the
models.
* Some models have the “0” position of the CHRONOGRAPH 1/10-second hand at 3
and 9 o’clock sides of the small dial. In that case, check if the hand is level with its
both ends pointing to those “0” positions.
● The CHRONOGRAPH minute hand moves correspondingly with the CHRONOGRAPH
second hand.
● The hands move quickly if the respective buttons are kept pressed.
TIME/CALENDAR SETTING
● Do not set the date between 9:00 p.m. and 1:00 a.m. Otherwise, the date may not
change properly.
● 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.
* Turn the hands 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
not, the time is set for the P.M. period.
● When setting the minute hand, first advance it 4 to 5 minute ahead of the desired time
and then turn it back to the exact minute.

● While the crown is at the second click, do not press the buttons. Otherwise, the
CHRONOGRAPH hands will move. To reset them to “0” position, see “ADJUSTING
CHRONOGRAPH HAND POSITION” on page 4.
CHRONOGRAPH
● While the chronograph is counting, do not pull out the crown to set the time. Otherwise,
the chronograph operation cannot be made.
● The CHRONOGRAPH 1/10-second scale and hand differ in design and shape depending
on the models.
* Some models have the CHRONOGRAPH 1/10-second scale graduated on the upper
half of the small dial and the hand which is so designed that both ends can indicate
the elapsed 1/10 second. In that case, read the marker on the scale where either end
of the hand points to.

Battery : SEIKO SR920SW
If the chronograph is used for more than 60 minutes a day, the battery life may be
less than the specified period.
As 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.
We recommend that you contact an AUTHORIZED PULSAR DEALER for battery
replacement.

● 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.

• Before using in water, be sure the crown is pushed in completely.
• Do not operate the crown and buttons when the watch is wet or in
water. If used in sea water, rinse the watch in fresh water and dry it
completely.
• When taking a shower with the water resistant 5 bar watch, or
taking a bath with the water resistant 10, 15 or 20 bar watch, be
sure to observe the following:
* 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.
* Pressure in bar is a test pressure and should not be considered as corresponding
to actual diving depth since swimming movement tends to increase the pressure
at a given depth. Care should also be taken on diving into water.
** We recommend that you wear a PULSAR Diver’s Watch for scuba diving.
