Knowledge:

Crystal:

The clean cover over the watch face. Three types of crystals are commonly found in watches:

1. Acrylic crystal – made of an inexpensive plastic that can have shallow scratches buffed out. 2. Mineral crystal- comprised of several elements that are heat-treated to create unusual hardness for scratch resistance. 3. Sapphire crystal- the most expensive and durable of the crystals. A non-reflective coating on some sport styles prevents glare.
