Why Do Top Watch Brands Love Sapphire Watches

Before answering this question, you must explain clearly what sapphire is. Whether it is natural sapphire or synthetic sapphire, it is one of the hardest substances on the planet, with a hardness of 9 on the Mohs scale-in addition to diamond in nature, there is nothing harder than it. ‘If the owner allows it, you can use a stainless steel knife or screwdriver to scratch it to see if there are any scratches.
What is a sapphire mirror?
Before answering this question, we must first explain what sapphire is. The main chemical composition of sapphire is alumina, which is originally colorless and transparent, but it is blue due to the inclusion of iron oxide and titanium oxide. If it contains chromium oxide, it is called ruby ​​because of its red color. The sapphire mirrors currently installed on watches are actually alumina trioxide with impurities such as iron oxide and titanium oxide removed. Chemically speaking, there is no difference between synthetic sapphire and natural crystal, and it is colorless because no other elements are added There is no ‘blue’ color for transparency. Aluminum trioxide is made from pure alumina at high temperature into original synthetic sapphire, which is then cut into diamonds by diamond tools and then polished into a mirror. Due to the high cost of processing tools, this is also one of the reasons for the higher cost of sapphire crystals. The technology of synthetic sapphire was invented in the 19th century. It has been used in watches since the 1960s, and now the top watch brands generally use sapphire glass.
Whether it is natural sapphire or synthetic sapphire, it is one of the hardest substances on the planet, with a hardness of 9 on the Mohs scale-no diamond is harder than it in nature. Note that what is said here is not in nature, not that it is not on earth. Some man-made silicon-carbon compounds can reach a hardness of 9 and can also scratch sapphire. Many construction and decoration materials also use silicon carbon compounds, such as artificial stone, so if there is friction in these places, it is possible to leave scratches on the sapphire glass.

In ‘The Rogue Dragon Crosses the River’, the fake Rolex used by the pheasant to frighten people will break instantly, and the true Rolex will never do this. This is also due to the high hardness of sapphire. Watches made of sapphire have higher shock resistance, tightness and strength than other materials. From the perspective of the current watch industry, although the hardness is higher than sapphire, and even higher than diamond materials are constantly emerging, but from the perspective of cultural awareness, or from the investment direction and scale of watchmaking industry Look, in the foreseeable future, the sapphire mirror is still an identifier of the top watch, and it is still a factor of the quality of the top watch.
“Several’ don’t know ‘about the mirror of the watch:
有 Is a watch with a Plexiglas mirror valuable?
If you want to collect an antique watch, it is most likely a Plexiglas mirror. But if you want to collect a new watch, you must choose a sapphire glass. Many collectors prefer the moist surface of Acrylic mirrors. This is because the acrylic mirror is curved, so the case can be made thinner without affecting the movement of the hands. However, plexiglass is easy to be scratched. It only takes one year, and many small scratches can appear on the surface of the plexiglass.

Is the sapphire glass better?
Yes. It will not be scratched. Sapphire is very hard and is an inevitable choice for top watches. For example, all new Rolex watches use sapphire crystals. However, like glass, it is more brittle and easily broken. Therefore, once this sapphire mirror is broken, the resulting maintenance costs will be very expensive, because watchmakers must carefully check to ensure that no sapphire debris is left in the movement before replacing the lenses. In addition, it is a powerful fingerprint collector, FBI’s favorite.
Can I change my plexiglass watch to a sapphire watch?
I can’t. Because the thickness of the case is different. Under normal circumstances, the mirror surface of sapphire is thicker than that of plexiglass. Maybe you can find the right size sapphire crystal, but this will also destroy the waterproof performance of the watch. In addition, as a result of this, many manufacturers will refuse to provide maintenance and repair for your watch.
How to identify the three materials of the mirror?
First, you can tap the mirror with your finger and listen carefully to the sound. Acrylic mirrors sound like plastic, while glass sounds thicker. Secondly, from the perspective of weight, the acrylic mirror is the lightest and the sapphire mirror is the heaviest. Because sapphire’s thermal conductivity is very good, when you touch it with your hands, you will have a cold feeling. Because the mirror surface of sapphire is much smoother than the mirrors of the other two materials, if you drop a drop of water on the sapphire mirror, the water droplets will not spread easily, and the other materials will be scattered. ‘The most reliable method is a scratch test, although it’s not very practical,’ says Johann Jorgo, Baume & Mercier’s New York technical director. If the owner allows, you can use a stainless steel knife or screwdriver to scratch Check it out for any scratches.
