for covering the case of a wrist watch: distinctive features
Choosing a wristwatch is not
as simple as it may seem at first glance. You should take into account many
nuances to buy a reliable, stylish, original and practical accessory. The type
of mechanism, design, size, type of glass and strap or bracelet, and brand are
taken into account. But it is also important to pay attention to what
composition is used to cover the case. Only high-quality materials are able to
ensure high aesthetics of the wristwatch throughout the entire period of
operation. Let's look at what types of coverage are used, what are their
features and differences.
What
coatings are used for watch cases
There are a lot of options
for coatings used in wristwatches, but the following options are most often
used:
1.
PVD,
2.
IP,
3.
DLC.
Let's look at each option in
more detail.
PVD
Physical vapor deposition or
PVD is a technology that involves several ways to obtain coatings. All of them
are United by one-the deposition is applied by direct condensation of a
vaporous substance in a vacuum environment and at an elevated temperature.
Manufacturers of accessories do not disclose what specific composition they
use. These are brand secrets. They are only satisfied with the inscription in
the description "housing with PVD coating". However, all manufacturers
claim that the materials used are absolutely eco-friendly and safe for both
humans and nature.
But at the same time, the
application technology itself is standard and does not belong to the secret
one. Everything happens in the following sequence:
·
in a vacuum environment, steam is formed from
the material to be used for spraying;
·
the generated hot steam is fed to the
accessory housing under a small pressure;
·
from temperature changes, it settles on the
metal;
·
it turns out the thinnest film, only a few
microns.
The surface of the watch
does not require any further processing.
When you see the
corresponding phrase about PVD coating in the description, you should
understand that this is an excellent accessory that is resistant to abrasion,
scratches and other defects on the surface. It also gives the product increased
resistance to corrosion. This coating is widely used in the production of
watches for divers and models with high water protection.
Some experts claim that PVD
coating appeared in the 60s of the last century, but in fact this technology
was developed by Michael Faraday in the 1830s. Currently, vacuum coating is not
only used in the manufacture of watches. It is widely used in the production of
car wheels, medical products, some types of bladed and firearms, and products
used in the aviation and space industries.
One of the key advantages of
such a coating is high reliability, long service life with a minimum increase
in the thickness of the case and its weight.
IP
Ion plating or IP coating
for short is one of the subspecies of PVD, namely, improved in terms of
resistance to corrosion and scratches. The key difference between these
technologies is that there is another additional layer that allows you to give
the product any of the shades. It all depends on what color dye is used.
One of the stages of
obtaining such coverage is "bombing". In this case, microparticles of
the working substance are fed to the accessory body with a much higher
intensity, which ensures the most dense and complete staining.
DLC
Already from the name
Diamond-like-carbon it becomes clear that this coating is one of the best,
although the most expensive. It uses carbon with unique diamond properties.
This technology involves feeding decayed carbon molecules to the watch case,
which, upon contact with the surface, form a film of increased hardness on it.
In addition to resistance to corrosion and mechanical effects, this coating is
resistant to chemicals and electric current.
During the experiment, it
was proved that the DLC coating applied to the surface of medium-quality
stainless steel increases the service life of the accessory from 1 week up to
85 years.
As you can see, the quality
of the coating is an important point that should be taken into account when
choosing a wristwatch. Best-Time online store offers a wide range of men's,
women's, and children's accessories for every taste and level of income.
