Sapphire, as one of the materials used in modern watches, is renowned for its high hardness and wear resistance. However, even with such excellent physical properties, it can still be worn out in certain specific situations. Here, we will explore in detail under what circumstances sapphire mirrors are prone to wear and explain the reasons behind it.

1、 Basic characteristics

Sapphire, also known as synthetic sapphire or sapphire crystal, is a material made of aluminum oxide (Al ? O ∝) through high-temperature and high-pressure treatment. Its hardness is second only to diamond, therefore it has high wear resistance. However, high hardness does not necessarily mean resistance to wear in all situations, as the occurrence of wear is closely related to multiple factors.

2、 Wear and tear analysis

1. Strong physical impact

Although sapphire crystal mirrors have strong hardness, cracks or scratches may still occur under strong physical impacts, such as accidental drops or strong impacts. This type of wear is often caused by the mirror being subjected to pressure and impact forces beyond its tolerance limit.

2. Chemical erosion

Sapphire has good resistance to most chemicals, but certain strong acids, bases, or corrosive substances may still cause damage to it.

3. Long term friction

Although sapphire has high hardness, it may also experience wear and tear when in contact or friction with hard objects for a long time. For example, if the wearer frequently engages in high-intensity physical activity or sports, the watch mirror may rub against other objects, resulting in surface scratches or wear.

3、 How to protect

1. Avoid strong physical impacts

To avoid strong physical impact on sapphire watch mirrors, wearers should be careful to avoid accidental drops or strong impacts. When engaging in high-risk activities, it is recommended to remove the watch or place it in a safe location.

2. Stay away from chemical substances

In order to prevent chemical substances from corroding sapphire watch glasses, wearers should try to avoid exposing their watches to strong acids, alkalis, or corrosive substances.

3. Properly keep it safe

When not wearing a watch, it should be properly stored in a dry and clean environment, avoiding direct sunlight and high temperatures. In addition, the watch should be avoided from coming into contact or rubbing against hard objects to reduce the risk of wear and tear.

Although sapphire has strong hardness and wear resistance, it may still be subject to wear and tear under strong physical impacts, chemical erosion, friction with hard objects, and improper cleaning and maintenance. Therefore, wearers should pay attention to avoiding these potential risk factors and take appropriate measures to protect the integrity and aesthetics of sapphire crystal glasses.
