Tachymetre
slower, such as a bicycle, you must use a shorter
distance because the elapsed time must fall within
the second range.
For this example, it took 36 seconds for a cyclist
to travel 1/4 of a mile. Reading the TACHYMETRE
dial displays a speed of 100mph, but the cyclist only
traveled 1/4 of a mile, so the actual speed would be
1/4 of that or an average speed of 25mph over the
quarter mile.
Example No. 2 – To measuring something much
7.2 - 60
Using the TACHYMETRE scale
The TACHYMETRE dial is mainly used to compute an average speed after noting how long it takes to travel a
fixed distance (like one mile or one kilometer), but it can also be used to compute many other things.
The dial is a logarithmic scale that uses this formula to compute:
The chronograph second hand indicates 1/10, 1/4, 1/2, 1, 10, 100 or 1,000 etc. units (miles, objects, pounds
etc.). When stopped, the second hand points to the number on the TACHYMETRE scale by which the number
of units (1, 10, 100 or 1,000 etc.) must be multiplied to obtain per-hour production rate or per-hour speed.
TACHYMETRE DIAL = 3600 / Elapsed
Time In Seconds
seconds. The second hand, stopped as the mile
marker is passed, reads 120 on the TACHYMETRE
scale. Average speed of the car is 120 x 1, or 120
miles per hour.
Although decimal units (100 liters, 1 mile, 10
kilometers) make computing simple, in practice, the
TACHYMETRE scale can be used to calculate
velocities and production rates from any number of
units.
Example No. 1 – A car covers one mile in 30

More Examples:
Suppose you wanted to measure the speed of a jet airplane. After traveling 10 kilometers, you noted that 40
seconds had elapsed. The TACHYMETRE dial displays 90, but you traveled 10 kilometers, so the answer
would be 10 times that, or 900 km/hour.
You can also measure other things, like fuel consumption. Suppose a pound of fuel took 48 seconds to
burn. The chronograph second hand indicates on the TACHYMETRE dial that you are burning 75 pounds of
fuel per hour.
timed for 30 seconds produces 72 parts. Stopped at
the 30-second mark, the chronograph second hand
points to 120 on the TACHYMETRE scale; the
production rate of the machine is 120 x 72, or 8,640
parts per hour.
Example No. 4 – A manufacturing production line
A
START/STOP
Example No. 3 – A copier makes 10 copies in 45
seconds. The sweep second hand was thus stopped
at the 45-second mark, which coincides with the
figure 80 on the TACHYMETRE scale. The hourly
rate of this copier is 80 x 10, or 800 copies.
A
START/STOP
NOTE - The scale is valid for all elapsed times from seconds to seconds. If the duration of the event is
outside this range, then the answer on the dial is not valid. Some of the following examples show ways to get
around this limitation.

Navigating by sun’s position: The direction will be accurate if you are using true local time without any
adjustment for daylight savings time. The further you are from the equator, the more accurate this method
will be.
In the northern hemisphere, bisect the angle between the hour hand and the 12 o'clock mark and set the
bezel’s S (30s) indicator to that point. Hold the watch horizontal and point the hour hand at the sun; the
bezel’s N indicator will be pointing North. If there is any doubt as to which end of the line is north,
remember that the sun rises in the east, sets in the west, and is due south at noon. The sun is in the east
before noon and in the west after noon, so set the bezel’s S (30s) indicator to the left of 12 in the AM and
to the right of 12 in the PM.
In the southern hemisphere, point 12 o’clock at the sun instead of the hour hand, the midway point between
the hour hand and 12 o’clock will be the North/South line.
*
*
*
*
*Note: If your watch is set for Daylight Savings Time instead of Standard Time, use the midway
point between the hour hand and 1 o'clock to determine the north-south line.

Miscellaneous
At 68 F (20 C), sound travels at 344m or 376yds / 1,129ft per second in air at sea level.° °
Example: Sea level temp is and
lightning to thunder measured time is 17.4
seconds. Distance of lightning strike point
is:
17.4s x 1,129ft = 19,644ft
17.4s x 376yds = 6,542yds
17.4s x 344m = 5,986meters
OR:
17.4s / 4.68s = 3.72 miles
17.4s / 2.66s = 6.54 thousand yards
17.4s / 2.91s = 5.98 kilometers
68 F °
At 32°F (0°C), sound travels at 332m or 363yds /
1,089ft per second in air at sea level.
Therefore, at 32°F (0°C) sound will travel:
1 mile / 1,760 yards / 5,280 feet in
1,000 yards in
1 kilometer in
4.85 seconds
2.75 seconds
3.01 seconds
NOTE:
Therefore, 68 F (20 C) sound
1 mile (1,760 yards / 5,280 feet) in
1,000 yards in
1 kilometer in
To estimate the distance to an event (such as an
explosion, muzzle flash, lightning, etc.), measure
the time from the visual flash to the sound and
multiply the seconds by the per second speed.
For example the measured lightning to thunder
time at 68 F is 10 seconds. 10 x 344m or
376yds / 1,129ft would produce 3,440m or
3,760yds / 11,290ft. (2.14miles)
Alternately, you can divide the measured time at
68 F by 4.68 to get miles (10s / 4.68 = 2.14miles),
or 2.66 for thousand yard distance, or by 2.91 for
kilometers.
