Definition and Function

A wall clock is a timepiece that measures time in hours and minutes, sometimes seconds. Its purpose is to allow people to tell time better and, thus, manage their lives more efficiently. The wall clock is found in homes, businesses, schools, and anywhere time awareness is critical.

Overview

A wall clock is typically round but can be square, rectangular, or more geometric in design. They can be very small (six inches in diameter) to quite large (over 24 inches). A wall clock is most commonly white with black numbers or black with white numbers. There are decorative wall clocks as well, which serve the purpose of the timepiece but have a more aesthetic function as the watch becomes a part of the room’s design.

Specific Components and Explanations

Clock Face

The clock face is the transparent covering in front of the wall clock that has numbers or markers associated with the hour. It generally has twelve markings or numbers that indicate the hour. There are sometimes minute or second markers for more careful documentation of time.  
The Hands

The thin rotating hands of a clock are as follows:

• Hour Hand: The small hand which indicates what hour it is.
• Minute Hand: The slightly longer hand which indicates what minute it is.
• Second Hand: The longest, skinniest hand which indicates what second it is.

Clock Mechanism

The clock mechanism of a clock refers to the inner workings that make the hands move. In a battery-powered clock, this is referred to as a quartz crystal oscillator. Quartz generates electricity, which causes it to vibrate at a specific frequency that keeps time. Therefore, when a current is generated, the hand moves (as the current dictates) in increments of time relative to the vibrations.

Battery Compartment

The battery compartment of a clock is located on the backside; it’s a small compartment that houses an AA or AAA battery that powers the clock mechanism.

Visuals 

Conclusion

The Wall Clock is a product that has been around for ages and helps the quality of human life better than almost anything else. It started with mechanicals and ended up with the battery-operated version found on every wall these days. It’s the most utilized functional and aesthetic device across all settings, available in dollar stores and antique stores alike, inexpensive and easy to find wherever one may be.
