What are the main parts of a watch called?

The main parts of a wristwatch are the case, dial, hands, crystal, crown, movement and strap or bracelet. The case houses the movement, which keeps time, while the dial and hands display it. The crystal protects the dial, and the crown is used to set the time. The bezel forms the rim around the crystal, while the lugs attach the strap or bracelet to the case. Depending on the model, Jowissa watches feature mineral glass or sapphire crystal.
