Are sapphire crystal watch faces any good?

　　Sapphire crystal is a type of crystal glass synthesized through artificial compression. Nowadays, the crystals of most watches are made of sapphire, so are sapphire crystals actually any good? Are they scratch-resistant? Xiaoya will explain this in detail below.

　　What is a sapphire crystal?

　　The sapphire crystals fitted on watches nowadays are actually aluminium oxide with impurities such as iron oxide and titanium oxide removed. Chemically speaking, synthetic sapphire is indistinguishable from natural crystal. Because no other elements are added, it is colourless, transparent, and devoid of any "blue" hue. Aluminium oxide is produced from pure alumina at high temperatures to create raw synthetic sapphire, which is then sliced into discs using diamond tools and subsequently polished into watch crystals. The cost and consumption of processing tools are very high, which is one of the reasons why sapphire watch crystals are relatively expensive.

　　Top watch brands generally use sapphire crystals nowadays.

　　Advantages of sapphire crystal

　　Sapphire is extremely hard, it cannot be scratched, and it is the inevitable choice for top-tier watches. Whether natural sapphire or artificially synthesized sapphire, it is one of the hardest substances on Earth, with a hardness reaching Mohs 9. In nature, other than the diamond, there is nothing harder than it. Please note that this refers to nature, not that it does not exist on Earth. The hardness of certain man-made silicon carbides can also reach 9, which can scratch sapphire as well. Many construction and decoration materials also use silicon carbides, such as artificial stone and so on, so if friction occurs in these places, it is possible to leave scratches on the sapphire watch crystal.

　　Disadvantages of sapphire crystal

　　Like glass, it is relatively brittle and easily shattered. Therefore, once a sapphire crystal is shattered, the resulting repair costs will be extremely expensive, because the watchmaker must carefully inspect the movement to ensure no sapphire fragments remain inside before replacing the crystal. Aside from this, it is a formidable fingerprint magnet, so it needs to be wiped frequently to remain bright and spotless.

　　How to care for a sapphire crystal?

　　If there are scuffs or minor scratches on the sapphire crystal, you can drop one or two drops of clean water onto the crystal, squeeze a small amount of fine-textured toothpaste and apply it to the scratch on the watch, and then gently wipe back and forth using a soft lens-cleaning cloth or cotton ball. This will remove the scratches and make the crystal look like new. Sapphire crystals are susceptible to scratches, so care and protection should be observed during wear to avoid bumps and knocks. Minor scratches on the watch crystal can be removed yourself, but when the scratches are relatively severe or you are unable to resolve the issue yourself, it is best to take it to a professional watch repair shop to handle it, avoiding greater damage caused by improper handling.

　　Following these brief insights into sapphire crystal watch glasses, Anya would like to recommend a top-tier replica watch featuring a sapphire crystal glass.
