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.
TACHYMETER
[for models with tachymeter scale on the dial]
To measure the hourly average speed of a vehicle
“90”(tachymeterscalegure)x
1(kmormile)=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”

second hand:
20 seconds
Tachymeter
scale : “180”
Ex. 2: If 15 jobs are completed in 20 seconds:
“180”(tachymeterscalegure)x15jobs=2700jobs/hour
on tachymeter scale:
“90”(tachymeterscalegure)x2(kmormile)=180km/hormph
“90”(tachymeterscalegure)x0.5(kmormile)=45km/hormph
