I see that Citizen watches are all made of sapphire glass, is there a fake sapphire glass? How to te

Sapphire glass is not a natural sapphire, it is artificial, because the hardness is close to sapphire, so it is called sapphire glass, and Citizen watches are not all sapphire glass watches, there is a mark, "sapphire", if the watch is ** and has this mark, it must be sapphire, parallel goods are difficult to say. Generally this mark is on the dial, and rarely on the back cover. It's not that sapphire glass won't have scratches, it's just a little stronger.

However, there is a part with a date magnifying glass that is not made of sapphire, so it is usually the easiest to draw there.

Hello, currently Citizen.

The watch glass is divided into crystal and sapphire.

Crystal glass is a type of inorganic glass that has been specially strengthened, so it has the characteristics of high transparency and is not easy to damage.

Sapphire glass.

Its hardness is second only to diamond, with high transparency and difficult to scratch, but sapphire glass is not incapable of scratching, and should avoid bumping or friction with hard objects in use, so as to avoid damage caused by improper use.

In addition, the identification of sapphire material needs to be tested by professional technicians and instruments, if you have any doubts about the glass material, you can mail it to the Beijing maintenance service center for identification.

Sapphire glass refers to the synthetic DU sapphire-like glass, the main components of which are alumina (Al2O3) and DAO silica.

Edition. It can be produced easily and cheaply in the laboratory. Synthetic sapphires, which are very different from natural sapphires, are generally used in the manufacture of watch mirrors.

It is an abrasion-resistant material. Although these materials are resistant to abrasion, they cannot withstand strong impacts, and some materials of the same or higher hardness, such as grinding stones, sandpaper, nail chips, granite, concrete walls, etc., may scratch their surface.

So don't think of it as expensive, a Citizen watch for a few hundred dollars can be used quite affordably.

Hello, the current sales of Citizen watches in Chinese mainland are more than 1000 yuan. For watches that are significantly below the market price, extreme caution should be exercised and cautious purchases.
