▲
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

main dial that corresponds to the
measured seconds, and the
tachymeter scale it indicates gives
the average number of jobs

Ex. 1
▲
“180” (tachymeter scale figure) x
1 job = 180 jobs/hour
CHRONOGRAPH
second hand:
20 seconds
Tachymeter
scale: “180”
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/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.
* 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.

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.
