Illumination:
It is the self-powered micro gas tube (H
3
) 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 H
3
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.
4. 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.
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 modied to BALL Standard.
