What is sapphire crystal
Sapphire crystal is not actually a glass, and it is a synthetic material with high resistance to wear, transparency, and high-temperature tolerance, making it a premium material for manufacturing luxury watches.It is made of pure aluminum oxide, which is melted and crystallized at high temperatures to form a single crystal structure,as it is extremely hard and durable. That’s why sapphire glass is one of the important watch case parts.
The sapphire watch crystal is the watch with sapphire crystal glass because sapphire glass can protect the dial and hand against shock. If your watch has sapphire crystal, it means it has the highest quality glass today.
Plane sapphire crystal VS Single doomed sapphire crystal VS Double doomed sapphire crystal
According to the original structure of sapphire, it is divided into plane. single doomed and double-doomed crystal sapphire.
If there is no special requirement, watchessy will use a plane sapphire watch.
The structure of single doomed sapphire glass is thick in the center and thin at the edges. The side near the dial is flat and the side facing out is raised. This structure will emphasize the magnifying effect of the face, making the dial full of visual tension and allowing the wearer to read the time easily.
316L, 904L, ceramic or tungsten steel cases come with crystal sapphire glass. Because some premium watch brands favor sapphire glass, the case is also made of a better material.
The Double Doomed crystal sapphire glass has a structure where both sides are raised and the overall thickness is more uniform. Such a structure will enhance the depth effect on the dial, making the whole dial look more three-dimensional and better showing the three-dimensional beauty of the watch.
The watches manufacturers can choose which structure of the watch glass to use according to the style of the watch, the price, and the guests.
Benefits of Sapphire watches crystal
Sapphire watch glass, a high-quality synthetic glass, has the following three advantages:
Durability and scratch-resistance
Sapphire glass is a very hard material that ranks higher than mineral glass. It is made with high temperature and high pressure, making it very resistant to everyday wear and tear. In contrast, mineral glass materials are easily scratched and damaged, while sapphire glass can withstand wear and pressure from daily use because of its higher hardness and better durability.
Clarity and anti-reflective properties:
Sapphire crystal glass has high transparency and clarity. Its perfect optical properties can eliminate optical interference and refraction, providing a better and more realistic viewing experience. Sapphire glass undergoes special treatment during production to reduce reflection and glare, and to maintain its surface flatness and high clarity in various lighting conditions. This special treatment is called anti-reflective film.
Longevity and maintenance
Sapphire crystal of watch is manufactured with precision, ensuring its quality remains superior. It has been developed and optimized for long-lasting life, and its special neutral coating treatment provides good resistance to wear and corrosion, allowing it to be used for a longer time. Because of the special treatment during production and manufacturing, sapphire glass has a very smooth surface that is easy to clean and maintain.
Sapphire crystal is good for watches, especially in luxury watches. Sapphire crystal is the first choice. Sapphire’s strength, scratch resistance, durability and transparency make it the first choice for high-end (especially dive watch) watches.
Sapphire Crystal Quality Grades
Sapphire crystal quality can be evaluated based on the following three aspects:
Types of Sapphire crystal
There are three types of sapphire crystals, namely Natural Sapphire crystal, Flame Fusion Sapphire crystal, and Czochralski Sapphire crystal. Among them, Czochralski Sapphire crystal is considered the highest quality because it can produce high-purity and high-transparency sapphire crystals.
Properties of high-quality Sapphire crystal
The properties of high-quality sapphire crystal include high hardness, high transparency, high thermal conductivity, high resistance to thermal shock and chemical corrosion, and high resistance to scratching and wear. High-quality sapphire crystals have a uniform color, high crystal orientation and low defect density, which results in better optical characteristics.
Factors that affect Sapphire crystal quality
The factors that affect sapphire crystal quality include crystal defects, impurities, crystalization method, and crystal growth rate. The presence of impurities and defects degrades the quality of sapphire crystals. High-quality sapphire crystals are made through strict quality control measures that focus on selecting proper raw materials and using advanced crystal growth methods.
How to Choose a Sapphire Crystal Watch
Choosing sapphire crystal watches involves considering the following three factors:
Is a sapphire crystal worth it?
Before choosing a watch sapphire crystal, ask yourself, is sapphire crystal worth it? Is it better to choose affordable mineral glass or expensive sapphire crystal glass?
