Clocks have been around for probably as long as humans have existed. Therefore, if one were to examine the long history of clocks, then it would be quite extensive and would take you back to the most ancient times in history. After all, time has been one of the most essential resource available to humans.

Sundial Clocks

This is the oldest type of clock known to man. In this method of telling time, ancient folks utilize the sun, specifically the shadow of the sun, in accordance to a circular disk that will indicate exactly what time of day it is. One flaw to this system of clock is that it is too dependent on the sun and cannot be used during night or any day where the sun is non-existent.

Water Clocks

This type of clocks originated in Egypt and involved two water containers, with one higher than the other. A tube connects both containers that enable water to travel from one to the other. For each container, there is a mark that indicates the time of day.

Pendulum Clocks

This was the initial practical clock invented, which also consist of a minute hand. Therefore, this type of clock is able to indicate time more accurately as compared to the ones listed above. Still, a problem exists in that the pendulum often stops after swinging for a while and had to be restarted.

Quartz Crystal Clocks

As the name implies, this type of clock utilizes quartz, which is a type of crystal that looks like a glass. When the quartz crystal is applied with electricity, pressure, or voltage, it creates some sort of vibration or oscillation. This vibrating motion enables the movement of the clock’s hands. Since it was invented in the 1920s, quartz crystal clocks were known to be one of the first type of clocks to accurately tell time.

Modern Clocks

Since the ancient times wherein people relied on nature to tell what time of day it is, clocks and their methods of telling time has largely evolved. Today, clocks can be used anytime of day. Plus, most of them are now powered by batteries and will continue to run for long period of time.

Desk Clocks

This type of modern clocks are best used at the office. Indeed, when you are too busy attending to your office works, it is easy to lose track of time. Hence, you have an accessible means of checking the time, especially if you have a deadline to beat. On top of that, having a desk clock also exudes a sense of professionalism and awareness of time amongst your co-workers and boss.

Alarm Clocks

For anyone leading a hectic lifestyle, alarm clocks are one of the most essential items to have. For instance, you have an early morning meeting at the office, you can rely on alarm clocks to wake you up on time, especially if you cannot rely on your body clock to naturally wake you up in the morning. But even alarm clocks have their own sub-categories of clock types such as Travel Alarm Clocks. These are most convenient for traveling businessmen who wants to stay within their schedule.

Other more stylish types of clocks that are available in various stores include the howard miller clocks and collectible mantel clocks. Aside from their functionality, clocks are also considered as collectible items.
