Athens after-sales center hotline: 400-823-7120 Athens after-sales network: 14D, 14th floor, Hunter International Finance Center, 33 Viaduct Road, Dusi, Guiyang Introduction to Sapphire Crystals 1. Sapphire has high hardness. Watches made of sapphire have higher shock resistance, sealing performance and strength than other materials. This is also an important factor in the quality assurance of top watches. 2. The sapphire mirror currently installed on the watch hand is actually aluminum oxide with impurities such as iron oxide and titanium oxide removed. Chemically speaking, there is no difference between synthetic sapphire and crystal. Because no other elements Phenibut on sale are added, it is colorless and transparent, and there is no “blue”.  3. Alumina is made of pure alumina at high temperature to make the original synthetic sapphire, then cut into wafers with diamond tools, and then polished to the table mirror. Because of the high cost of processing tools, this is also one of the reasons for the high cost of sapphire crystals.  4. The technology of synthesizing sapphire was invented in the 19th century, and it has been manually used in watches since the 1960s. Now top watch brands generally use sapphire crystals.  5. Sapphire is very hard and is an inev Phenibut Manufacturers itable choice for top-level watches. But like glass, it is fragile and easily broken. Therefore, once the sapphire mirror is broken, the maintenance cost will be very expensive, because the watch division must be carefully checked before replacing the lens to ensure that no sapphire fragments are left in the movement.  6. In addition, it is a powerful fingerprint collector, so it needs to be wiped frequently to be bright and flawless. Whether it is natural sapphire or synthetic sapphire, it is one of the hardest substances on the earth, with a hardness of 9 on the Mohs level Phenibut Manufacturers . In nature, apart from diamonds, there is nothing harder than it. Note that it is said that there is no in nature, not that there is no on earth.  7. Some man-made silicon-carbon compounds have a hardness of 9 and can also scratch sapphires. Many construction and decoration materials also use silicon-carbon compounds, such as artificial stones. Therefore, if friction occurs in these areas, scratches may be left on the sapphire crystal. 8. The plexiglass crystal cannot be replaced with a sapphire crystal because the thickness of the case is different. Usually the sapphire mirror is thicker than the plexiglass (table mirror). Maybe you can find a sapphire crystal of the right size, but it will also destroy the water resistance of the watch. In addition, as a result, many manufacturers will refuse to provide maintenance for your watch.
