Case Back: Transparent. The transparent back cover is usually used to protect the watch movement from direct damage. These watch cases can also increase the durability and strength of the watch movement.
Crystal: Sapphire Crystal. Sapphire crystal is the best choice for most people. It is a special anti-reflective coating that minimizes light reflection and provides scratch resistance without affecting its luster.

Tips: The A watch is applied with mineral glass instead of sapphire.
