In this article, we will explore the evolution of clocks throughout history, tracing their development from their beginnings to the present day. This includes the history of sundials, water clocks, hourglasses, and others. It cannot be said that a single inventor created the clock; humankind has strived to invent and develop clocks since ancient times. Some may find it hard to believe that people in the past learned to tell time and make clocks by observing the cycles they witnessed in nature, such as the cycles of the sun and moon and the four seasons. Here, you will learn about many of the clocks invented by humankind throughout history, such as:
Sundial Date
We will discuss methods of timekeeping throughout history, starting with the history of the sundial, which is considered the oldest method of timekeeping. It simply reflected the cycles that occur in the sky for people to see, and its use was common in ancient Greece. It relied heavily on shadows to measure time using parts of a circular device that indicated the time between sunrise and sunset. However, the drawback of this method is that we cannot tell the time in dark or nighttime conditions.
History of water clocks:
As we've learned about the history of sundials, they weren't always useful; for example, they didn't work on cloudy days and certainly didn't work at night. Nearly 3400 years ago, the ancient Egyptians devised a method for telling time. They realized that water flowed from a hole in a water-filled vessel at a constant rate, and this idea led to the invention of the water clock. In these ancient water clocks, water flowed from a hole near the bottom of a stone vessel, and markings carved into the vessel's walls indicated the hours, allowing people to tell the time by observing the amount of water remaining.

The history of hourglasses:
An hourglass consists of two glass spheres (chambers) stacked on top of each other and connected by a narrow opening. The upper sphere is filled with fine sand that seeps into the lower sphere. The hourglass can be turned over when the sphere is full, and the time it takes for the upper sphere to appear empty is considered a measure of time.
History of mechanical watches :
The mechanical clock appeared in Europe approximately 700 years ago. These early clocks operated using rising and falling weights to measure the elapsed time, driven by a continuously rotating gear. Unlike modern clocks, which lacked hands, mechanical clocks didn't tell time. Instead, they signaled the passage of an hour, but this system wasn't very accurate, often losing about 15 minutes each day.
Throughout history, clocks have relied on various power sources to operate, such as gravity, springs, and electricity. The invention of mechanical clocks is attributed to the Chinese inventors Liang Lingzhan and Yi Xing. However, they did not become widespread in the West until the 14th century. Clocks were used in monasteries during the Middle Ages to regulate prayer times. Clock development continued through the ages until the first pendulum clock was designed and built by the Dutch scientist Christiaan Huygens in the 17th century.
As watches evolved over time, in 1904, pilot Alberto Santos-Dumont commissioned his friend, the French watchmaker Louis Cartier, to design a watch for him to use on his travels. Wristwatches had already been invented in 1868 by Patek Philippe, but as women's bracelets, pieces of jewelry. Since pocket watches were impractical, Cartier created a wristwatch for Santos, which became the first practical men's wristwatch.
History of incense clocks :
One of the strangest ways of telling time was by the nose. This happened in China in the fourteenth century, where people used an incense clock, which was a special clock with a maze-like engraved channel. This channel contained various types of incense, and the clock users would light the incense at one end. No sooner would one type of incense be lit than a full hour would have passed, and every time the smell of the incense changed, people would realize that an hour had passed.
There have been amazing timekeeping devices throughout history. In the early ninth century AD, the English King Alfred the Great had a clock made of six candles , each thirty centimeters long. The servants in his palace would light the candles throughout the day, one after the other, as each candle took about eight minutes to burn per centimeter, and thus the six candles took 24 hours.
The history of the elephant clock :
Among the amazing clocks is also the Elephant Clock, which was made by Al-Jazari. It is a water clock that set the time twice a day at sunrise and sunset. It is in the shape of a huge elephant, topped by a small house. The elephant is driven by robotic men, and there is a dragon and a phoenix. This clock incorporated into its design the civilizations of the ancient world, where the elephant represents the Indian civilization, the dragon represents the Asian civilization, and the phoenix represents the ancient Egyptian civilization.
Over time, watchmaking evolved significantly, leading to the creation of pendulum clocks and clocks with hairsprings that maintain a constant oscillation period. This evolution continues to the present day. Despite these advancements, clockmaking has not yet achieved absolute timekeeping accuracy due to the influence of pressure and temperature on the length of the pendulum or spring. This influence causes variations in the oscillation period used to measure time. It has been shown that the only clock that cannot err in measuring time is the Earth, as the time it takes for one rotation on its axis is absolutely constant.

First small wristwatch
It is worth mentioning that the first small portable wristwatch was made in the sixteenth century by a German locksmith named Peter Henlein. After more than ten years of research and study, Henlein was able to invent a small spring called the mainspring, which is a spring that supplies the watch with the energy needed to operate it. The manufacture of this type of watch became famous in Switzerland, England, and France. Then these watches were developed by adding a hand that indicates the minutes, and later they were able to add a hand that indicates the seconds.
Throughout history, the need arose for a watch suitable for women; thus, a small watch was invented that could be worn on the wrist, known as the wristwatch. During wars, soldiers found they needed a wristwatch instead of carrying one in their pockets to easily tell the time, and so wristwatches began to be worn by both men and women. Watches continued to be developed to become more accurate and efficient. Electronic wristwatches, powered by a small battery, were created, and even more accurate wristwatches than electronic ones emerged, known as quartz watches.
Quartz clock appearance
The first prototype of a quartz watch dates back to 1967, produced by researchers at the Electronic Watch Center in Neuchâtel, Switzerland. In 1969, the first quartz watch was manufactured in Japan by Seiko under the name Astron. The operating principle of quartz watches is based on supplying a quartz crystal with an electric current from a small battery. This current causes the quartz crystal to vibrate, and this movement is transmitted to the watch hands. The number of vibrations of the quartz crystal was approximately 8192 vibrations per second (Hz) for older watches, while modern watches have increased this frequency to 32768 vibrations per second (Hz).
Over time, watches became increasingly popular, especially among the upper classes, becoming an essential part of personal luxury for those who could afford them. As a natural progression, watches began to be adorned with precious stones and transformed into jewelry. It became customary for gem-encrusted watches to have a uniform outer thickness and tiny holes drilled around their circumference. These holes hold the precious stones that are set in the watch. This is an extremely delicate process, as the craftsman works with holes no larger than a tenth of a millimeter in diameter.
Hours in our day
Today, electricity is the preferred power source for watches, as it is for any device that can utilize this power. Small batteries are used to power electric watches. In one such motor, an electromagnet attracts a magnetic balance. Another common power source is galvanic, which consists primarily of a balance and an oscillating hairspring driven by the attractive force between a copper coil and a magnet. But there are also watches that operate using what is called resonant energy. This type of energy uses a very small electric tuning fork to provide the power for the watch. This particular mechanism is what one might call an electronic watch. These are the most accurate of the watches we have discussed so far because they operate at much higher frequencies than those found in balance-powered wristwatches.
As we enter the age of science fiction and are confronted daily with countless semi-smart electronic and computer devices, the market is now overflowing with watches of every shape and with a wide array of features and capabilities. Many of these watches display the time digitally, and some can even tell you the time verbally upon request. Some watches remain classified as jewelry, while others incorporate a phone, a digital camera, or all of these. But regardless of how much their design has changed or how many other uses have been added, watches are still made out of that same historical need: to tell time.
Swiss watches
Swiss watches are now among the best types of watches ever, and their wonderful design is the main reason that makes them among the best watch brands. In addition to the elaborate designs, they also enjoy quality, luxury, and high technology that qualifies them to be exported all over the world and sold in the most famous international stores. The export of watches in the world is generally increasing, as there are a group of countries that control the watch industry worldwide. Among the most important of these countries that export watches is China, which occupies the first place in terms of the volume of exports. However, Switzerland is the one that controls watch manufacturing in the world, as the watches that it manufactures are sold at the highest price in the world in terms of watch prices, so it is the most famous country in watch manufacturing.
Having learned about the history of sundials, water clocks, hourglasses, and other clocks, we now see a wide variety of watches, ranging from classic to digital and sports, and evolving into advanced electronic watches, including men's , women's , and diamond watches.
