Synthetic Sapphire Sapphire Watch Case with High Wear Resistance
Sapphire—a material that is almost as hard as diamond—has been used in watches for years as the crystals over the dials (in part due to being extremely scratch-resistant). It’s not the easiest material to work with, due to its extreme toughness. It can be difficult to cut and mold, but boundaries are pushing by cutting blocks of it into unique and fun shapes.Everything from traditional round cases to tonneau, square, and even wildly unexpected shapes that resemble car engines or jets.

FATURES
1. High mechanical strength: the permeable infrared window material should have sufficient strength to withstand the high-speed movement of the speed pressure load;
2. Good thermal stability: the permeable infrared window material should be able to withstand the temperature shock caused by pneumatic heating and height changes, transmission ratio and refractive index should not change significantly with the change of temperature;
3. Good chemical stability: through infrared window material exposed to air, should be able to prevent the atmospheric salt solution or corrosion gas corrosion, and not easy to moisture;
4. High optical transmission rate, must be able to effectively transmit ultraviolet to medium infrared radiation;
5. Good optical characteristics, small optical scattering and good uniformity of refractive index;
Meets large window requirements.
