Material knowledge of watch glass

1. Sapphire is a kind of natural diamond, which has high anti-wear and anti-corrosion effect after being synthesized with alumina. The hardness is 2200-2300 Vickers (seven times the hardness of steel), the Mohs hardness is 9, its hardness is second only to diamond, high hardness, good light transmission, low friction, high temperature resistance, wear resistance, commonly used as a watch mirror and see-through bottom cover.

Can the sapphire crystal be ground on the ground or ordinary glass? No, because the ground or ordinary glass may contain diamonds or diamond powder and debris, if it is encountered, the sapphire crystal will be scratched; The soft material of the crystal sticks to the sapphire crystal, causing the sapphire crystal to be scratched. This is an imaginary scratch, which can be restored by the master polishing.

2. Mineral crystal glass

The hardness is 500-800 Vickers, and the Mohs hardness is 5. Usually, the hardness is strengthened after polishing, but the hardness is still slightly inferior to the sapphire crystal mirror.

3. Synthetic glass

Plastic glass refers to acrylic. Most of the watches in the past used this material, and there are still many watches in use. The disadvantage is that it is easy to be scratched, and the transparency is slightly poor, but because it is elastic and not easy to break, it is also called safety glass. Although plastic glass is easy to scratch, when it does get scratched, you can sand it directly on the glass to make it smooth, and you don’t have to replace the lens unless the scratches are too deep, and the price is cheap.

4. Anti-glare mirror

What is the anti-glare mirror that is often heard?

To put it simply, the anti-glare mirror is to electroplate a multi-layer film on the lens to make it adhere to the lens to prevent light refraction. On a watch with a large mirror curvature. And it is divided into double-layer anti-glare glass and single-layer anti-glare glass. The difference is that the former is electroplated on both the inner and outer sides of the lens, while the latter is only coated on the inner side of the glass, and the effect of the two is not much different.
