out under a forced vacuum in a
coating chamber. This procedure
is one of the most modern and
ecologically sustainable coating
technologies.
PVD coatings are highly adhesive,
hard and abrasion-resistant.
They are extremely smooth and
particularly suited to coating
watch parts. These coatings can
be single-layer, multi-layer or can
be applied in graduated layers.
The layer thickness ranges from
1 to 5 microns, although in some
cases, just 0.5 microns or 15
microns and more can be applied.
Depending on the initial material
and the inert gas employed, a
wide range of PVD coatings can
be applied. Essentially, these fall
into four main groups: nitrides,
carbides, oxides and carbons
(Diamond like carbon).
Diamond Like Carbon (DLC)
Coating.
$
As mentioned above, the DLC
coating process is a PVD coating
process using diamond like carbons.
This durable and friction-reducing
coating with an anthracite-coloured
appearance essentially comprises
diamonds measuring just a few
nanometres across, coated in
graphite. This structure is commonly
referred to as Diamond-Like
Carbon (DLC). Thanks to its
diamond-like layered structure,
DLC layers possess exceptionally
hard surface proper ties. They are
substantially harder and more
wear-resistant than ultra-hardened
grades of steel, and are excep-
tionally corrosion-resistant, as
well as being skin-friendly.
Sapphire crystal.
d
Most Oris watches are now equip-
ped with sapphire crystal on the
dial face. This fact is noted on the
case back.
With a Moh hardness of 9,
sapphire crystal is the hardest of
all grades of crystal. It comprises
a synthetic sapphire and is
exceptionally scratch-resistant.
Only diamond, with a Moh
hardness of 10, is harder than
this. In addition a sapphire crystal
is much more impact-resistant
than mineral glass.
To improve dial readability, the
internal faces of most Oris
sapphire crystal have anti-reflective
coating.
To obtain even clearer dial
readability, a few Oris models
have sapphire crystal which has
anti-reflective coating on both
sides. This outer layer can
become scratched in the course
of wearing the watch. This
constitutes normal wear and tear
is not covered by the guarantee.
Metals for cases and straps.
The 316 L stainless steel used
by Oris is robust, durable and
complies with the stringent
dermatological requirements for
preventing nickel allergies. The
nickel directive applicable in many
countries states that objects
which are in direct, prolonged
contact with the skin are only
allowed to release 0.5 µg of nickel
per cm
2
skin/week. The nickel
content in an alloy is not the
crucial factor. The rate of nickel
release on the skin is much more
important. Altough 316 L stain-
less steel is not entirely nickel-
free it does not release nickel.
The grade 2 titanium used by Oris
is a pure grade of titanium that
can also be used in implants and
which possesses an excellent
resistance/expansion ratio. Tita-
nium is 45 % lighter than steel,
and is also corrosion-resistant,
skin-friendly and has a warm feel.
PVD coatings.
O
Physical Vapour Deposition (PVD)
is a process where an exceptionally
pure, solid coating material is
used to generate an ionized metal
vapour which forms a coating
mixture with inert gases. Through
condensation, a thin layer is
deposited onto the surface of the
watch. The PVD process is carried
