• Strap: Our straps are made of finest 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.

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 amount of radiation exposure due to all natural sources is about
2.4 mSv a year - though this figure 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
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 such minor exposure.
