One-Piece Sapphire Crystal Watch Case And Top Glass For 6497 Movement

Watches with precious metal cases will also show a high level of collection significance and sales value if they are equipped with complex functional centers. But there are always exceptions, there is an emerging material in the bezel, it is not precious metal, but precious properties than precious metals have been unprecedented, and amazingly, this material of advanced complex table is often valuable, from the recent products, we will find that the price of such watches sometimes far greater than precious metal watches. What kind of material is so sought after? It's neither ceramics nor highly visible technology materials such as carbon fiber, but sapphire crystal glass that we've known in the past to make watch mirrors or transparent bottom covers.

Sapphire is one of the world's hardest materials, sapphire Mohs hardness is 9, the entire process of making a sapphire case is very complex, highly technical, long production cycle. temperature to continue the subsequent analysis process.

Sapphire is one of the hardest materials in the world. Diamonds are the first hard in the world and sapphires are second. Diamond Mohs Hardness 10, Sapphire Mohs Hardness is 9. The average stainless steel is 5.5, titanium is 6, and gold is 2.5 to 3.

Pre-press molding like sapphire takes 430 hours, polishing takes 350 hours, etc.

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;
