TACHYMETER
[for models with tachymeter scale on the dial]
To measure the hourly average speed of a vehicle
Ex. 1
“90” (tachymeter scale figure) x
1 (km or mile) = 90 km/h or mph
Tachymeter
scale: “90”
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

To measure the hourly rate of operation
1Use the chronograph to measure
the time required to complete 1
job.
2Locate 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.
Ex. 1
“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
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

ADJUSTING CHRONOGRAPH HAND POSITION
●The “0”position of the CHRONOGRAPH 1/10-second hand differs depending on the
models.
NOTES ON OPERATING THE WATCH
●The CHRONOGRAPH minute hand moves correspondingly with the CHRONOGRAPH
second hand.
●The hands move quickly if the respective buttons are kept pressed.
TIME SETTING
* 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.
●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 extended position, 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.

10
English
●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.

● 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.
