All Favre-Leuba watches have a high-
quality sapphire glass. This is made from
synthetically manufactured sapphires and is
extremely resistant to scratches. In order to
ensure that the watch can always be read
very clearly, the sapphire glass used has a
non-reflective layer on one or both sides.
This may become scratched during wear.
However, this is a natural form of wear and is
therefore excluded from the warranty.
Favre-Leuba uses first-class leather for its
straps. In order to ensure that they remain in
good condition for as long as possible, we
recommend
• avoiding contact with water and moisture
as far as possible to prevent the strap from
discoloring and changing shape;
• avoiding exposure of the strap to direct
sunlight over a long period, as the color
may fade;
• keeping the strap away from greasy or
oily substances, solvents, detergents and
cosmetic products.
Favre-Leuba straps made from high-quality
rubber display outstanding water resistance
and resistance to ageing. Along with excellent
mechanical properties, they are also
characterized by high resistance to
aggressive and extreme environmental con-
ditions. We recommend cleaning a rubber
strap regularly with soapy water, especially
on the inside.
Some Favre-Leuba cases have a PVD
coating. During physical vapor deposition
(PVD), an ionized metallic vapor is created
from a very pure, hard coating material,
which forms a coating compound in
combination with noble gases. A thin coating
is deposited on the surface of the case by
condensation. PVD processes – which are
among the latest and ecologically most
sustainable coating processes – are carried
out using high vacuum conditions in a coating
chamber.
In order to allow you to see your Favre-Leuba
watch without difficulty even in poor light
conditions, the hands and index marks on
the dials of most models are provided with
Super-LumiNova
®
luminous pigment. Super-
LumiNova
®
is entirely free from radioactive
additives and is charged by sunlight or
artificial light, so a watch should not be
permanently protected from these light
sources. As the luminescent pigments retain
their properties, they can be recharged any
number of times. As soon as darkness falls,
the luminosity is at its strongest. Within the
first 60 minutes, it declines relatively quickly,
but gradually thereafter. As a result, you can
see the time display very clearly, even after
five to six hours.
