Parts of a Pocket Watch

A pocket watch is a type of watch that fits into the pocket instead of being worn on the wrist. The pocket watch has been used since the late 16th century and is still a popular heirloom to pass down from generation to generation.

Chain
- The chain (or fob) is connected on the side of the watch. The chain is used to attach to a belt loop or waist coat with a ring on the opposite end.
Winding Stem
- The winding stem on a pocket watch is located on the 12 o'clock position or the 3 o'clock position. Winding stems that are located at 3 o'clock have the nickname of sidewinders.
Hunter Case
- A pocket watch with a hunter case has a spring-loaded cover attached to the watch. This cover protected the watch face from scratching or damage of the crystal.
Key Set
- Earlier versions of the pocket watch do not feature a winding stem on the outside of the watch. Instead, pocket watches produced up to the 19th century have a key set in the back to wind the watch.
Mainspring
- Many pocket watches are powered by a mainspring. This type of spring needs to be wound about every 40 hours to keep time.
