In watch manufacturing,Sapphire lensesUsually refers to artificial sapphire or synthetic sapphire, which is a synthetic material with chemical composition and physical properties similar to natural sapphire. It is usually composed of alumina and a small amount of other additives, made through high-temperature and high-pressure processes. Due to its high hardness and transparency, it is widely used for protecting watch mirrors. The following are the application benefits of sapphire mirrors.

1. Wear resistance

Sapphire is a wear-resistant material that is harder than most metals and can withstand various scratches and collisions in daily life. This means that the watch is not subject to severe impact and is unlikely to be damaged.

2. Transparency

Sapphire is transparent, which means it allows more light to pass through the surface of the watch. This makes the watch more readable and makes the details of the dial more clearly visible. In addition, due to the transparency of sapphire, it can increase the depth and dimensionality of the watch, making it look more complex and textured.

3. High temperature resistance

Sapphire can withstand high temperatures because it has a high melting point. This means that even in high heat environments, it will not melt or deform. This makes sapphire a durable material that can maintain its appearance even in high temperature environments.

4. Anti reflection

Another advantage of sapphire is its anti reflection ability. Watches often reflect surrounding light, which can make it difficult to read or cause glare. Sapphire lenses can reduce these issues, making the watch easier to read and thus improving its practicality.

Sapphire lenses refer to materials obtained through chemical reactions and artificial cultivation, which have a similar appearance and characteristics to natural sapphire and are often used as mirror materials in watch manufacturing. It should be noted that natural sapphire is also used in the mirror production of some watches, but this is relatively rare in watches. Natural sapphire, due to its scarcity and high value, is generally used in jewelry and other fields.
