BALL’S TIME
Webb C. Ball was born in Fredericktown, Ohio
on October 6, 1847. In the early years, Mr. Ball
was recognized as having an interest in accurate
time. When Standard Time was adopted in 1883,
Mr. Ball was the rst Cleveland jeweler to use
the time signals sent from the Naval Observatory
in Washington D.C., bringing accurate time to
Cleveland. For many years, as people walked
past his store, they would pull out their watches
and set the time. The phrase, “BALL’S TIME”,
came to mean the absolute correct time all over
Northern Ohio.
Webb C. Ball was instrumental in establishing watch standards and the
inspection system that required all watches and clocks used on the railroads
to be checked by competent watchmakers. It is important to recognize and
applaud Webb C. Ball for inventing the rst successful system to be accepted
on a broad scale. It was his system that set the standards for the railroads; it
was his system that helped establish accuracy and uniformity in timekeeping.
It was his system that resulted in railroad time and railroad watches being
recognized as STANDARD, whenever accuracy in time was required.
Webster Clay Ball, founder
of BALL Watch Company
Brand Spirit
Freedom represents what humans live for: Free will and the chance to
pursue their dreams.
TheAmerican Railroads brought freedom to the country, the opportunity to
travel and explore the new frontiers. The powerful locomotives sparked the
spirit of adventure in the American people, while the men of the railroads
were the heroes of the machine age. Then BALL Watch Company proudly
served the men of the railroads, just as we support the world-class explorers
of today.

Movement:
BALL has worked with top Swiss movement manufacturers to build our
precise and dependable movements under the most rigorous conditions.
BALL watches are then adjusted and modied to BALL Standard.
Illumination:
It is the self-powered micro gas tube (3H) that gives the watch excellent
legibility even in the absolute darkness and under adverse conditions. This
light source on all BALL watches does not require batteries or re-exposure,
and lasts for up to 25 years. However, the brightness of 3H micro gas lights
will deteriorate over the years, but can be restored by replacing with new
dial. For most of the models of the Engineer Hydrocarbon series, the
markings on the bezel are lled with luminous paint that emits the light to
which it has been exposed during the day.
Water-resistant:
The water resistance of BALL watches ranges from 30m/100ft to
3,000m/9,850ft, depending on the model chosen. The water resistance of
a timepiece will be impaired if the crown is not properly screwed-in. The
patented crown protection system of the Engineer Hydrocarbon models
ensures the crown returns to its proper position.
Performance
At BALL Watch Company, all watches are made to live up to our motto:
Since 1891, accuracy under adverse conditions
Case:
The case material used in our collections ranges from superior quality, high-
grade stainless steel, titanium, gold or metal coated with Diamond-Like
Carbon. The automatic watches of the Engineer Hydrocarbon, Engineer
Master II and Engineer II series are specially equipped with an antimagnetic
soft iron inner jacket.
Crystal:
The crystal is made of anti-glare sapphire.
Shock-resistant:
All BALL watches are constructed to withstand impact test, according to
the norm ISO 1413, which is carried out on a machine to simulate the effect
of a free fall onto a hard wooden oor from a height of one meter. The
Engineer Hydrocarbon series undergoes a more rigorous 7,500Gs impact
test, to ensure its impeccable shock resistance.
ENGLISH

The Engineer Hydrocarbon, Engineer Master II, and Engineer II watches
are equipped with superb antimagnetic cases constructed with corrosion-
resistant ferric stainless steel materials. Furthermore, the inner workings of
the watch are protected by a soft iron inner jacket consisting of a sub-dial,
a ring surrounding the movement and a double-bottom. This special alloy,
reinforced by the shape of the case, prevents magnetic elds from penetrating
as far as the movement and having an adverse effect on its accuracy.
What does the term “antimagnetic” actually mean? The existing standard
is dened as follows: If a mechanical watch does not stop when exposed to
a magnetic eld of 4,800 A/m and subsequently does not deviate by more
than 30 seconds per day, it can be called “antimagnetic.” The Engineer
Hydrocarbon series certainly surpasses this standard with a protection up
to 12,000 A/m.
Sectional view of an anti-magnetic BALL watch case
Magnetism
The Greeks rst observed the phenomenon of magnetism around 600 B.C.
The natural magnet Fe3O4, a black ferrous oxide, was discovered in the
province of Magnesia in Turkey.
Magnetic elds produced by natural magnets are generally too weak to
disturb the accuracy of a mechanical watch. The same is not true, however,
of man-made magnetic elds. So where are we at risk to enter magnetic
elds in daily life? Near televisions, stereo systems and radios in our living
room. In the countless small electric motors used throughout our households.
In the doors of cars, refrigerators or cabinets. In the telephone or computer
monitor on your ofce desk. And in locomotives. Even brief contact with
these items is enough to magnetize a mechanical watch.

Swiss Night Reading Technology
How to read time from watches in dark
environments has been a topic of much research
in the watch industry. Applying luminous paints
to dial and hands - activated rst by radium, then
by tritium - has been standard practice since
the First World War but did not really satisfy
the manufacturers. After a quarter-century in
research and development work, BALL Watch Company is proud to
present an innovative Swiss laser technology that is considered the best
alternative available today. It is the self-powered micro gas tube known as
(3H) that gives the watch its excellent dark reading capability in any adverse
conditions. They provide superior night reading capability that is 100 times
brighter than the current tritium-based luminous paints. 3H gas tubes do not
require batteries nor to be recharged by an outside light source, or the use
of a press-button, and glow continuously for up to 25 years. You can read
off time from the watch quickly and safely in brightest daylight or deepest
night without adapting your eyes to the ambient light.
The 3H Swiss technology captures tritium safely in a very stable form,
as a pure gas sealed in a hollow body of mineral glass. Its exterior walls
are coated with a luminescent material, which gives off cold light when
activated by electrons emitted by the tritium. Light production is the same
as in a TV tube, when the electrons of the cathode ray beam hit the screen.
Please note that brightness of the 3H gas lights will gradually decline over
time, but can be restored by replacing with new dial.

ensure water resistance and to prevent possible damage to the movement.
Remarks:
Automatic watches acquire their energy from an oscillating weight that is
activated in response to the movements of your wrist. Depending on the
model, the power reserve ranges from 38 to 48 hours. Manual winding is
only necessary if the watch has not been worn for a long period of time,
or if it has stopped.
Depending on the type of movement, the accuracy of a mechanical
movement may vary one to two minutes per week. Accuracy is strongly
inuenced by the way the watch is worn.

8. Amortiser®anti-shock system
MODELS: DC2036, DC3036, PM2096
By locking the rotor of the automatic movement, the Amortiser®anti-shock
system reduces the risk of damages during high-impact activities.
When the Amortiser®is locked in the “ON” position, the rotor cannot spin,
which protects the movement in case of shock. In this setting, the watch
operates like a manually-wound watch.
When the Amortiser®is unlocked in the “OFF” position, the rotor spins
freely and can wind the automatic movement.
The Amortiser®device, patented and exclusive to BALL Watch, secures the
movement against extreme shocks. This feat of micromechanics is characterized
by a ring of protection, both protecting magnetically and enveloping the
movement to absorb shocks in combination with a locking mechanism for the
automatic rotor. On the caseback, the form of an airplane propeller (DC2036,
DC3036) or a submarine (PM2096B) operates the lock that secures the oscillating
mass of the watch movement for the wearer. These ingenious systems protect the
mechanism not only against lateral impact but also vertical impact.

7. Slide Chronograph
MODELS: CM3888
Position [X]: Normal position
Position [0]: Manual winding position
Position [1]: Day/Date adjustment
Position [2]: Setting the time
To operate the slide-bar:
[S0] Normal position
[S1] Start/Stop the chronograph
[S2] Reset the chronograph
The patented Slide Chronograph system includes a circular slide bar tted
around the case that allows the trigger, stop and reset of the chronograph
in one and the same control integrated in the case at the 9 o’clock position.
The intuitive movement required to activate the mechanism consists of
making the external control slide along the case.
• To trigger the chronograph, move the slide bar clockwise [S1]. The slide bar
then automatically returns to its original position [S0]. Asecond movement
clockwise [S1] stops the chronograph, and a third movement [S1] starts the
chronograph again.
• To reset the chronograph, move the slide bar counterclockwise [S2]. This
movement only functions when the counters are stopped.
See above instructions for “Automatic Watch” , with the following changes.
ENGLISH

At the beginning of a pulsation, start the chronograph counter by pressing
push button [P1]. Press again when the 15 pulsations/respirations have been
recorded. If after the 15 pulses, the operator stops the chronograph counter
at 10 seconds, reading from the stopped second hand on the pulsemeter
scale will result in a pulsation rate of 90 beats per minute.
Combined with the single-button chronograph to allow for quicker
measurement of pulse and respiration rates, the 15-pulse scale also minimizes
human error due to reaction time to ensure a more accurate reading.

“Automatic Chronograph” to reset the chronograph counter to zero position.
To compute the speed of a vehicule over a certain distance, press the top
chronograph button [P1] to start timing. At the end of the xed distance,
press the button again. If the time elapsed is 45 seconds, the second hand
should point to the gure 80 on the Tachymeter scale. If the xed distance
is one kilometer then the car is traveling 80 kilometers per hour.
The Fireman Skylab (CM1092), Fireman Storm Chaser (CM2092) and
Fireman Storm Chaser DLC (CM2192) have a tachymeter scale on the
outer bezel for measurement of elapsed times up to 1 minute.
The inner spiral of the Trainmaster Pulsemeter (CM1010) is a tachymeter
scale capable of measuring elapsed time of up to 3 minutes. If for example,
the time elapsed is 1 minute 30 seconds, the second hand will point to the
gure 40 on the 2nd ring of the Tachymeter scale. Over a distance of 1 mile,
the car is thus traveling at 40 miles per hour.
The wearer can nd the correct speed
per hour by recording the time needed
to travel a certain distance.

A chronometer is an extremely accurate watch. It takes its name from
the Greek words chronos + metron meaning “to measure time”. A BALL
chronometer is a highly accurate, mechanical watch whose precision has
been tested and veried by the Ofcial Swiss Chronometer Testing Institute
(Contrôle Ofciel Suisse des Chronomètres, or COSC, in French).
Before issuing the certicate, the COSC conducts elaborate precision tests
on each BALL movement using cameras and computers and analyzes the
data. The COSC performs seven different tests. Failure to meet the minimum
standard in any one of the tests means that a movement is rejected. Here is
a brief summary of the testing procedures:
※ Test 1
Mean daily rate:After 10 days of tests, the mean daily rate of the movement
must be within the range of -4 to +6 seconds per day. The COSC determines
the mean daily rate by subtracting the time indicated by the movement 24
hours earlier from the time indicated on the day of observation.

※ Test 2
Mean variation in rates: The COSC observes the movement rate in ve
different positions (two horizontal, three vertical) each day over 10 days for
a total of 50 rates. The mean variation in rates can’t be more than 2 seconds.
※ Test 3
Greatest variation in rates: The greatest of the ve variations in rates in
the ve positions can’t be more than 5 seconds per day.
※ Test 4
Horizontal and vertical difference: The COSC subtracts the average of
the rates in the vertical position (on the rst and second days) from the
average of the rates in the horizontal position (on the ninth and tenth days).
The difference must be no more than -6 to +8 seconds.
※ Test 5
Greatest deviation in rates: The difference between the greatest daily
rate and the mean daily test rate can’t be more than 10 seconds per day.
※ Test 6
Rate variation due to the temperature: The COSC tests the movement’s rate
at 8 degrees Celsius (46 degrees Fahrenheit) and at 38 degrees Celsius (100
degrees Fahrenheit). It subtracts the cold temperature rate from the hot
temperature rate and divides by 30. The variation must be no more than
0.6 seconds per day.
※ Test 7
Resumption of the rate: This result is obtained by subtracting the average
mean daily rate of the rst two days of testing from the mean daily rate
of the last test day. The resumption of rate can’t be more than 5 seconds.
16. SpringLOCK®
MODELS: CM1052, DM2076, DM2176, NM3022
In case of shocks, the patented SpringLOCK®system guarantees that a
mechanical caliber remains accurate by protecting the balance-spring with a
"cage" designed to absorb the energy created when the watch is subjected to
external impacts. Such impacts can cause standard mechanical movements
to vary by up to approximately 60 seconds a day. The SpringLOCK®system
reduces their effect by up to 66%, thus ensuring that the caliber remains
accurate.

17. Power reserve
MODELS: GP1052, NM1056, NM2058, PM1058, PM2096
The BALL watches with power reserve function feature an indicator that
displays the remaining power reserve on a hand. The indicator will turn
counterclockwise as the power diminishes. During manual winding or when
the watch is worn, the reserve indicator will move clockwise.
The natural movements of your arms wind the watch up automatically and
the energy will be stored up as power reserve. Manual winding is only
necessary if you stop wearing your watch for several days or if it stopped.
Remarks:
Do not overwind the watch. Manual winding should be stopped when the
power reserve indicator reaches the end of the scale. Continued winding
could damage the movement.
The display at bottom of the dial is the
power reserve indicator. It shows the
remaining power reserve in the watch in
hours. If the watch is not worn, or during
periods of low activity, the hand of the
power reserve indicator will wind down.
18. Moon Phase
MODELS: NM1082, NM2082
The Engineer Master II Moon Phase (NM1082) has been the rst moon
phase watch illuminated with the stunning 3H micro gas tubes. The moon
phase wheel is activated by a 59-tooth gear, which shows the changes of
the Moon’s phases as it goes through two of its 29.5-day cycles. The moon
phase disc is easily set via Position [1] of the crown.
Set the Moon Phase display by turning to the nearest Full or New Moon,
then moving forward by the appropriate number of days.
