Sapphire watch mirrors, as an important component of modern watches, have won the favor of countless watch enthusiasts with their unique wear and scratch resistance and crystal clear appearance. The technological content and exquisite craftsmanship behind it also reflect humanity's continuous pursuit and breakthroughs in precision manufacturing technology.

The main component of sapphire crystal mirrors is aluminum oxide, which is widely present in nature. However, the aluminum oxide used to manufacture the mirrors is not directly derived from nature. During the manufacturing process, impurities such as iron oxide and titanium oxide need to be removed to ensure the purity and transparency of the mirror. This specially treated aluminum oxide not only possesses excellent physical properties such as high hardness, high melting point, and high transparency, but also maintains stable chemical properties in harsh environments.

After obtaining the original synthesized sapphire, a series of complex processing steps are required to polish it into a watch mirror that meets the requirements of a wristwatch. Among them, polishing is a crucial part. Polishing sapphire crystal mirrors requires large milling machines equipped with high-precision control systems and advanced processing technologies to ensure that every polishing process of the mirror is precise and error free. During the polishing process, workers need to use rich experience and skills to continuously adjust the parameters of the milling machine and the angle of the cutting tools to ensure the flatness and smoothness of the mirror.

Sapphire that has undergone initial polishing, although already possessing the corresponding transparency and glossiness, still needs to undergo multiple processes of fine polishing to achieve the required finished product standards. These processes include polishing, cleaning, testing, etc. Each step needs to be strictly controlled to ensure the quality and performance of the watch mirror.

The wear and scratch resistance of sapphire crystal mirrors is attributed to their high hardness. In nature, only a few substances can surpass sapphire in hardness. Therefore, when friction occurs with other objects, its surface is not easily scratched or worn. This excellent wear resistance enables the watch mirror to maintain a clear and transparent appearance for a long time in daily life. High transparency is also one of the reasons why it is highly praised. Due to the removal of impurities such as iron oxide and titanium oxide, the transparency of the watch mirror is high, which can clearly show the movement and details inside the watch. This high transparency feature not only enhances the overall beauty of the watch, but also allows the wearer to more conveniently read the time and appreciate the operation of the movement.

Sapphire watch mirrors, as an important component of modern watches, benefit from their unique wear and scratch resistance as well as high transparency appearance, thanks to their material properties and exquisite craftsmanship. In the future development, with the continuous advancement of technology and the continuous improvement of processes, performance and quality will be further enhanced.
