The physical properties that can be brought about by the use of sapphire crystal mirrors

Time:2023-10-27

Sapphire watch mirrors have high hardness and scratch resistance, which are two important factors determining the quality of watch mirrors. Mohs is usually used to indicate the hardness of an object, for example, the hardness of mica is 1 Mohs, the hardness of diamond is 10 Mohs, the hardness of glass is 5.5-7 Mohs, and the hardness of sapphire reaches 9 Mohs, which means its hardness is close to that of diamond.

1. Improve the transparency of the watch

Sapphire crystal is a highly transparent material that allows the watch dial to be more clearly visible. Compared with traditional glass mirrors, sapphire mirrors are more transparent and can clearly display the structure and movement components below the watch dial, allowing people to better understand the internal structure and working principle of the watch.

2. Improve the wear resistance of the watch

High hardness, using sapphire mirror on the watch can improve its wear resistance and avoid scratches on the mirror due to long-term wear, which affects the appearance of the watch.

3. Enhance the aesthetic appeal of the watch

Sapphire watch mirrors have high transparency and glossiness, which can make watches more beautiful and elegant. In addition, under sunlight, it will present a unique luster, adding many highlights to the watch.

4. Improve the waterproof performance of the watch

The high hardness and density effectively improve the sealing performance of the watch case, making the watch more waterproof. At the same time, a smooth surface can prevent moisture from staying on the watch dial, preventing the watch from malfunctioning due to water intrusion.

5. Improve the resale value of watches

When a watch uses a sapphire mirror, it can not only improve the quality and performance of the watch, but also increase its collection value and resale value. Due to the material and craftsmanship, the production cost and selling price of watches are relatively high, which effectively increases the market value of watches.

When sapphire is used to make watches, its impact resistance, sealing performance, and strength are much higher than watches made of other materials. However, sapphire watch mirrors are fragile, which is why they can also be damaged if not properly maintained. For sapphire watches with obvious and deep scratches, they can only be sent to a professional watch repair shop for corresponding treatment.
