Pocket Watch

Pocket watches are portable time measuring instruments that are designed to be carried in a pocket or attached to a chain. They are typically small in size and have a hinged cover to protect the watch face. Pocket watches were commonly used before wristwatches became popular.

Pocket watches consist of several components, including:

1. Case: The outer covering of the pocket watch, usually made of metal or precious materials like gold or silver.

2. Dial: The face of the pocket watch, which displays the time. It typically includes hour markers, minute markers, and sometimes additional features like a second hand or date display.

3. Hands: The moving indicators on the dial that point to the current time. Pocket watches usually have an hour hand, minute hand, and sometimes a second hand.

4. Movement: The internal mechanism that powers the pocket watch and keeps time. It includes a mainspring, gears, and a balance wheel.

5. Crown: A small knob on the side of the pocket watch that is used to wind the mainspring and set the time.

Pocket watches can have various additional features, such as a chronograph (a stopwatch function), a moon phase display, or multiple time zones.

In the supply group "Instruments And Laboratory Equipment," pocket watches are classified as time measuring instruments because they are used to accurately measure and display time. They are often used in scientific experiments, historical reenactments, or as fashion accessories.
