WATCH ANATOMY 02

THE BACK OF A WATCH HAS THESE ELEMENTS:

case- back refers to the back of a watch. Some have transparent, sapphire-covered backs to reveal the movement.

Jewels, such as synthetic rubies, are often used as bearings for gears of an automatic or manual-winding movement.

lugs are the projected parts of a case that connect to a bracelet or strap. The shape can vary from one model to another.

rotor is a mechanical piece that winds and powers an automatic movement. The size may vary between watches.

strap is a wristwatch band that connects to the lugs. The material used may be leather, fabric, or various metals.
