Water-resistant:
The water resistance of BALL for BMW watches ranges from
50m/160ft to 100m/330ft, depending on the model.
Magnetism
The Greeks rst observed the phenomenon of magnetism around
600 B.C.
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 ofce
desk. Even brief contact with these items is enough to magnetize
a mechanical watch.
What does the term “antimagnetic” actually mean? The existing
standard is dened thusly: 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.”
Engineered for Perfection.
Case:
The case material used in our collections ranges from superior quality,
high-grade stainless steel or coated steel with Diamond-Like Carbon.
Crystal:
The crystal is made of anti-glare sapphire.
Shock-resistant:
All BALL watches are constructed to withstand impact test, according
to 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.
Movement:
BALL has worked with top Swiss movement manufacturers to build
our precise and dependable movements under the most rigorous
conditions. BALL for BMW watches are then adjusted and modied
to BALL’s Standard.
Illumination:
It is the self-powered micro gas tube (3H) that gives the watch
excellent legibility even in the absolute darkness. This light source
on all BALL watches does not require external charge, and lasts
for up to 25 years. The brightness of 3H gas lights will deteriorate
over the years.
