Sapphire Provides a amazing compromise between durability, transparency and cost. It is very hard 9 on the Mohs scale next to diamond, according to report, the sapphire glass is 3 times as hard than mineral glass.
Sapphire glass is the most resistant to scratches, you can use a sharp metal object like a knife to scratch the surface of it. It feels very hard, and the glass will not be scratched, it is sapphire crystal.It is an great choice for luxury watches.
Besides, Sapphire is also widely used in optics and chemistry because it has good corrosion resistance, perfect transmittance.
DISADVANTAGES OF SAPPHIRE CRYSTAL
As glass, it still has the commonality of glass, that is, it is brittle and easily broken. Which is also increase the cost for watchmaker. Othersides, the price of sapphire crystal is higher than mineral glass, if you don't have enough budget, sapphire crystal maybe is not a best choice for you.
Sapphire crystal is a synthetic material that is made from process (melt-seeding-put down-automatic growth-complete-annealing) of crystallising pure aluminium oxide at very high temperatures.

Nowadays Sapphire crystals are very popular with famous brand watches because of it's perfect fectures.Sapphire watch case is also gradually enter into market.
1. Thinner and Stronger than Standard Glass Windows
2. Transmits Wavelengths Ranging From UV to Mid-Infrared
3. Features Extreme Surface Hardness and Chemical Resistance
Sapphire crystals are the most beautiful of crystals — highly scratch-proof, easy on the eyes, and not expensive. They are more commonly seen on high-end watches and most limited-edition watches.
Sapphire crystals are extremely scratch-resistant and are considered a gem in the world of horology. Watch modders and collectors alike love a timepiece with a sapphire crystal, as it makes for a clean and beautiful look. The crystals not only protects your watch’s dial and face but also enhances the overall aesthetic.
Sapphire Windows are manufactured from single crystal sapphire, making them ideal for demanding applications (such as laser systems) because of their extreme surface hardness, high thermal conductivity, high dielectric constant and resistance to common chemical acids and alkalis. Sapphire is the second hardest crystal next to diamonds and, because of their structural strength, sapphire windows can be made much thinner than other common dielectric windows with improved transmittance. Chemically, sapphire is single crystal aluminum oxide (Al2O3), and is useful in a transmission range from 0.2 - 5.5µm
Sapphire is a precious gemstone, a variety of the mineral corundum, consisting of aluminium oxide (Al2O3) with trace amounts of elements such as iron, titanium, chromium, vanadium, or magnesium. Followings are features of Sapphire:
What is sapphire crystal used for?Typically in the luxury watch field nowadays, sapphire crystals are preferred. Sapphire is extremely strong and scratch resistant, making it the top choice for a fine timepiece. While sapphire is the more expensive of the three crystal (Mineral,Acrylic,Sapphire) choices, it has its advantages due to the scratch and shatter resistance.Following is a chart for your reference when you consider the size and waterproof:
Synthetic sapphire is commonplace in our everyday lives, as its desirable properties—optical, mechanical, thermal, chemical, and structural—have yielded an array of fascinating applications.
