Mirror maintenance
Nowadays, the most commonly used mirror material for watches is sapphire crystal. Sapphire is a colorless and transparent synthetic material, but it is not a natural sapphire crystal, just the same name. The hardness of sapphire mirror is very high, second only to diamond, and it is wear-resistant and scratch-resistant, which can be said to be the best mirror material at present.
When it is hit or touches the cement floor, it will wear or even break. The most direct way to meet this situation is to change a new mirror. But in order to avoid this situation, you need to take good care of your watch, be careful not to touch sharp things, and check the strap regularly to prevent it from falling to the ground after being broken.
Watch case maintenance
The maintenance of the watch case is some scratch problems. In general, the case will be polished or brushed, or both. Generally, if it's a shallow scratch, it's easy to handle. Simply throw a lamp or pull a thread to handle it. But if it is a deep scratch, it is not easy to handle.
In the advanced treatment, we must first determine the position, then polish it evenly with oilstone, then slowly smooth the scratched position with a magnifying glass, and finally polish it with sandpaper with appropriate granularity. Note that this is a very meticulous job and requires patience. Another point is that it is best to choose the sandpaper in jewelry industry, which will be easier to use.
