TECHNICAL DETAILS / INFORMATION
PVD COATING
This process is performed under vacuum (PVD = Physical Vapor Deposition).
Deposit of a thin film by the condensation of a vaporized form of the desired
film material (0.5-1.0 µm mainly titanium nitride) onto various workpiece sur-
faces (mainly watch case, watch bezel, crown, pusher, watch bracelet). The
advantage of PVD is that it is a thin but hard layer, resistant to corrosion, has
a strong adherence, offers many choices of colours (mainly 01-0.3 µm 18ct
gold 2N) and is hypoallergenic. Our PVD coating is equivalent to a 10 µm
galvanic coating.
QUARTZ MOVEMENT
AUGUSTE REYMOND® quartz watches benefit from the incomparable preci-
sion of quartz. These electronic movements gain their energy from a battery.
Their power reserve usually enables them to operate for more than 2 years in
continuous use. All you have to do is to set the time, and occasionally also the
date if your watch is equipped with a display of this kind (refer to the section on
« Settings ».). The quartz models are accurate to 3 minutes per year. If you ever
have a period when you might not be wearing your watch for a few weeks or
months, we would advise you to put it to one side, having first pulled the crown
out to the last position. You will see the second hand now stopped working. This
will substantially reduce power consumption.
SAPPHIRE GLASS
Sapphires may be found naturally or they also may be manufactured for indus-
trial or decorative purposes in large crystal boules from agglomerated alumi-
nium oxide (AI203). Artificial sapphire material is identical to natural sapphire,
except it can be made without the flaws that are found in natural stones. Sap-
phire glass is not only highly transparent, but is also extraordinarily scratch-re-
sistant. Sapphire has a value of 9 on the Mohs scale of mineral hardness (the
second hardest mineral, right behind diamond). Due to its extreme hardness,
sapphire is scratch proof and resistant to wear and chemical attack. We use
since many years this perfect material for all the top crystals on our AUGUSTE
REYMOND® watches.
