Sapphire glass is a popular choice for modern watch crystals due to its abrasion and scratch resistance. Its durability ensures that it will maintain its surface integrity even when in contact with metals, plastics, or other common materials. This article will explore these features and how they function in practical applications.

The manufacturing process of sapphire glass is extremely complex and meticulous. The process involves grinding alumina into a fine white powder, adding metal oxide, and gradually synthesizing it in a high-temperature furnace at 2050 degrees. This synthesis process is essential for ensuring the high hardness and stability of sapphire glass. Following a process of meticulous cutting and polishing, these sapphire stones are transformed into a variety of flat, arc-shaped, arched, spherical and other types of glass, each meticulously crafted to meet the exacting appearance requirements of various watch models. These glasses are of the highest purity and transparency, designed to be both elegant and stylish while also offering excellent abrasion and scratch resistance.

Sapphire glass is characterized by its high hardness, which contributes to its abrasion-resistant properties, making it capable of withstanding the wear and tear of most substances encountered in daily use. Its surface integrity is maintained even when in contact with metals, plastics and other common substances. This feature makes sapphire glass an ideal choice for watches, as they often need to maintain precise operation and an exquisite appearance in various complex environments.

In addition to its abrasion resistance, sapphire glass also boasts excellent scratch resistance. Scratch resistance refers to the ability of a material’s surface to resist scratches and damage. Sapphire glass, due to its high hardness and dense crystal structure, is able to resist the formation of scratches. Even when exposed to sharp external objects such as keys and nails, it retains its smooth and clear surface.

Sapphire glass, renowned for its durability and resistance to scratching, has emerged as a significant component in the manufacture of watches. The high hardness and dense crystal structure of the watch ensure precise operation and an exquisite appearance in a variety of complex environments. At the same time, when using the watch, users should also take care to avoid strong impacts and drops, as well as contact with substances of higher hardness.
