This refers to the transparent cover that is placed over the watch's face. Watch crystal is another term. You can make them from many different materials, but it all depends upon the watchmaker, their use, and the quality.
The crystal can be made from three types of materials: sapphire, mineral, and acrylic glass. Acrylic glass is plastic and is the most affordable. Plastic is flexible, resistant, and transparent.

Although it is very light, it cannot be broken. However, it can scratch easily. Although these scratches can be repaired, a professional should do the job. Acrylic watches are primarily intended for children, as it is well-known that children are not always very careful.
The material glass is another type of glass. This is the most common. This mineral glass is made from ordinary glass by heating it and adding chemicals.
Although this glass is susceptible to scratching, it is easily replaceable. Broken glass can cause damage to the internal mechanism. This can lead to damage to the interior of the watch, which can cause it not to function properly.
The sapphire crystal is the third type. This crystal is very hard and transparent, made from crystallizing aluminum oxide at extremely high temperatures. You can also buy watches with genuine sapphire glasses, but these are more expensive.
This glass is durable and is less likely to crack or shatter. A sapphire glass watch is expensive because of its precious stone. It is also shaped using diamond-encrusted tools. This type of glass is often used by the most well-known brands for their watches.
