In addition to directly caring for the inner parts of the watch, the shell determines to a large extent the performance indices of the watch, such as water resistance, dust protection, magnetic resistance, anti-shock resistance..
You may not have heard of much less common materials, but each has its own characteristics. Here are some of the common and unusual surface materials。
1. Fine steel
The most common material is characterized by indelible, non-modified, non-irradiated skin and environmentally friendly materials. They can polish, they can grind, they can plating all kinds of materials and they can stabilize. In general, 316 l steel and 904 l steel. 316l steel is the surface material commonly used in most wristwatch brands, consisting mainly of fe, cr, ni, mo, which is close to iron, is highly corrosive and of good quality. The 904l steel is exclusive to the rolex and contains nickel, chromium and copper, which are more resistant to corrosion and wear and tear than the 316l steel at three times the price。
2. Gold husks are luxuriant
Currently, the crust is mainly 18 k gold, 75 per cent pure gold, and absolute pure gold tables do not exist. Pure gold is too soft and too rigid to be shaped, and gold is mixed with other materials. 18k gold, too. It is common for 3ns of 18k gold, 4ns of 18k rose gold and 5n of 18k red gold, while 4ns and 5ns represent the high and low volume of copper, the difference being that the colours go from shallow to deep. “goldao” is the most famous, and its gold content is usually higher than conventional 18k, which the rolex refers to as 18ct gold。
Gold plating shell: gold plating process only. Only the surface is gold, and the surface is coated with a thin layer long enough to wear it。
3. Platinum watch shells
This platinum is not platinum, and in the watch industry platinum remains a form of gold, the main component of which is gold. It is a platinum-free white alloy made of gold smelting with other white metals. The platinum watch has a number of formulae and limits and has some collection value。
4. Gold watch shells
Platinum is a rare and expensive natural pure white metal, and only platinum can be called platinum. There are superiors that are never faded, never worn, and most wristwatches with platinum gold are of limited grade, and they contain a collection of spoils。
5. Ceramic shell
The weight of the ceramic wristwatch was reduced by about 60 per cent compared with the wristwatch of stainless steel material, and the hardness was about 10 times that of stainless steel material. The most important feature of high-tech ceramics is their resistance to wear and corrosiveness. No matter how long they are worn, ceramics make it look the same as when they are newly purchased. Adapting to body temperature does not tend to be responsive, and the disadvantage is fragile. Chanel chanel and radar are high-frequency users of high-tech ceramics。
6. Titanium metal surfaces
Silver ash translation has the advantage of being 30 per cent harder than steel, much lighter than steel, strong against corrosion and rust. A few wristwatches of titanium metal material: all-strip pilot series iw327006, 100-year mechanical timing series v1731110/bd74/109w/m20basa. 1, richandmir men's series rm010, wild big bang series 411. Nm. 1170. Rx, pena sea luminor 1950 series pam00389。
7. Sapphire surfaces
It's generally known that sapphire materials are widely used on the mirrors -- sapphire glass. There are sapphire husks, but rarely. High light, high hardness is not scratched by general materials. Prices are generally more expensive. The surfaces of sapphire material are not specifically recommended for routine wear。
Tungsten steel surfaces
The hardness is close to natural diamonds, it is not easy to wear, and the brightness is mirrored and never fades. Tungsten steel, which was originally a color -- silver -- can now be electroplated to gold, black. The disadvantage is not to fall, because it can break。
Carbon platinum hulls (prophaps)
Lighter than titanium metal, harder than titanium metal and very resilient. There's nothing wrong with it. The only thing that's wrong is that it's expensive! As in the episcopal oak offshore series 15706au. Oo. A002ca. 01 wristwatch。
10, copper
Copper is easily oxidized, corroded by sweat or allergic to skin because it is less perishable. So they all use steel for the back covers. But the current trend of retrogression prefers to oxidize the copper shell, and the process of oxidation deserves a fine taste. For example, when it's real, it's copper flying。
11, gold
Precious metal, a member of the platinum family, is silver and white and bright in colour. It is lighter in weight than platinum, harder in hardness, less oxidation and loss of light under normal conditions. More rare than platinum in purity, rareness and durability. The top world brands, such as jiangsedon, athens watch, katia, and palmer johnny, have used gold as a watch。
12. Plastics
The use of plastic watch brands is not very high-end, but fashion and practical. In casio, for example, most plastic surfaces are popular among young people。
There are also few materials, such as ceratanium, titanium metal surfaces, high-tech diamonds, carbon steel, ceramostm titanium metal ceramics, etc。
