Why Choose sapphire crystal?
Usually the default choice for higher-end watches, to many Sapphire is the optimal material when it comes to watch glass; primarily because it is the hardest crystal available.
Most sapphire glass found in wristwatches is actually synthetic (man-made) sapphire, rather than the naturally occurring material you may be familiar with. As with acrylic, this isn’t technically ‘glass’, rather, transparent crystallised Aluminium Oxide; usually produced in a laboratory. You will struggle to scratch a sapphire crystal with anything other than a piece of diamond.
While sapphire performs well against scratches, it is somewhat susceptible to shattering if exposed to heavy impacts. This is why certain watch types, for instance army watches, opt for more shatter-resistant options like acrylic. Nevertheless, unless you are wearing the watch in a particularly manual job or plan on dropping your watch on to hard surfaces, it’s less important than you may think. I’m yet to ever smash a sapphire crystal.

Sapphire is a single crystal aluminum oxide (Al2O3). It is one of the hardest materials. Sapphire has good transmission characteristics over the visible, and near IR spectrum. It exhibits high mechanical strength, chemical resistance, thermal conductivity and thermal stability. It is often used as crystal materials in specific field such as space technology where scratch or high temperature resistance is required
