7. Caring for your BALL watch
Like a car engine, we recommend that you have your mechanical BALL
watch checked, cleaned and lubricated by a BALL authorized service center
every three to ve years. This regular maintenance will prevent movement
wear due to the drying of lubricating oils.
Your BALL watch requires a certain amount of care. A few basic
recommendations will help you to ensure its reliability and keep it
looking new.
• Magnetic elds: The Engineer Hydrocarbon, Engineer Master II and
Engineer II collections are all equipped with soft iron inner antimagnetic
case for improved resistance. Nevertheless, please avoid placing your
watch on refrigerators or loudspeakers as they generate powerful
magnetic elds.
• Shocks: Although your BALL watch has been built to withstand shock
according to the highest standard in the industry, extreme impact against
this precision instrument should still be avoided. A strong impact on the
winding crown or the crystal can impair the water resistance or damage
the movement.
• Cleaning: Be sure to rinse your watch regularly with fresh water, especially
after it has been in salt water. This will help preserve its appearance and
running condition.
ENGLISH
• Strap: Our straps are made of nest calf, crocodile or alligator leather and
are protected against humidity. To prolong the life of your leather strap,
please avoid contact with water and dampness to prevent discoloration
and deformation. Should the strap be immersed in salt water, we suggest
that you rinse it with fresh water to prevent further damage. Please also
avoid contact with greasy substances and cosmetic products, as leather
is permeable.
8. Optimum Safety
Man has always been exposed to natural radiation arising from the earth as
well as from outer space. The radiation we receive from outer space is called
cosmic radiation or cosmic rays. On average, our radiation exposure due
to all natural sources amounts to about 2.4 mSv a year - though this gure
can vary widely, depending on the geographical location. Even in homes
and buildings, there are also radioactive elements in the air.
The wearer of an intact BALL watch is never exposed to any radiation.
Even the hypothetical and unlikely accident entailing the simultaneous
release of all tritium contained in H
3
gas tubes would present a very minor
internal irradiation. In that case, the wearer is exposed to a dose 30,000
times lower than the one due to average background radiation as stated
above. It is evident that it does not make sense to speak of a risk at all for
