Since the beginning of creation, man has advanced his civilization and history by making friends with time. And as a companion to human progress, watch has progressed through various evolutions over time.

There was a time when people knew the time by looking at the position of the sun. Even the first mechanical clocks made by man used this formula to position the sun based on time. That means time, sun, clock are members of a circle, complementing each other.

The shape, use, structure of watch have a beautiful evolution. Today’s digital clock is an evolution of its predecessor.

Let’s learn about the history of the evolution of watches.


The journey of clocks first started with sundials. There is no exact information about when and by whom this clock was invented. However, the oldest sundial found in Egypt dates back to 150 BC. Structurally, the structure of sundial is very simple. It has a long spike or pointer.

It is attached to a dial in such a way that the shadow of the thorn falls on the dial. The dial has markings for the various hours and minutes. At different times of the day, the hands cast shadows on different parts of the dial. Time was determined from this shadow.

This sundial was used in many countries of the world. These sundials ranged from small to huge. There were also small sundials that people could carry in their pockets or hands. Some giant sundials were erected on roadsides or in parks so that people can easily know the time. For example, the huge rectangular column called the ‘Luxor Obelix’ in Paris is a sundial.

But due to some problems of this watch, people keep trying to invent new watches. A major problem with sundials was that they could not be used at night. Also, this clock stops working even on cloudy days. Therefore, the use of this clock gradually decreased in number around the eighteenth century.

Water Clock

Water clocks with sundials were common in ancient times. It is believed that water clocks or clepsydras were in circulation in China about 5000 years ago. Many believe this clock was first used in Egypt.

The structure of the water clock was also simple. First, water was kept in a container. There was a leak under the pot. Through this leak, the water fell into another vessel below. The vessel below was divided into 24 sections. The time was determined by the amount of water collected in the bottom container.

This water clock is popular in many countries of the world. A water clock was not as problematic as a sundial, it could be used at day or night and could be carried anywhere. This water clock was used in school-college, office-court.

But despite all these advantages, the water clock had some disadvantages. This watch could not be used on ships. Besides, this watch was not working in cold countries. Because if the water freezes and turns into ice, the clock will stop. As a result, people were looking for alternatives to this water clock.


Hourglass is another ancient clock. When and where this watch was invented is unknown. However, it is believed that a monk invented this watch in the 8th century AD. The hourglass consisted of two equal funnel-shaped glass containers joined together. One container is on top of the other.

The upper container was filled with fine and clean sand. The sand from the upper pot slowly fell into the lower pot. It took an hour to empty the upper container. After one hour the clock was reversed. In this way, the watch was used all day. These clocks were widely used in Europe during the Middle Ages.

This clock is also depicted in many famous paintings. Currently, the clock icon is also used in the mouse pointing cursor on Windows operating systems of computers. This watch could easily be used on ships as it did not cause any problems with small movements. In that case a man was employed to wind the clock. This clock gained a lot of popularity as it did not have so many difficulties like sundial or water clock.

Fire Clock

People have used many things to tell time throughout the ages. Experimented with many things, fire is not excluded from this. In ancient times, people measured time by how long it took to burn a piece of wood. But it was very flawed.

Because some wood can burn in two minutes and some wood can take whole day. So something was needed that would burn evenly. A type of rope clock was used in ancient China. A rope was tied with several knots at equal distances. Then, if one end of the rope was set on fire, the rope would start burning slowly.

Time was measured by how long it took to burn from one node to another. After the invention of the candlestick, the use of candles to tell time began. Time was measured by how long it took a candle of a certain shape to burn. The candles were marked with different colors to indicate the time. This type of watch is widely used in many countries around the world.


The first fully mechanical watch was the ‘clock’. Many craftsmen have contributed to the creation of this watch. Some believe that Greek physicist Archimedes invented the first clock in 200 BC. He made clocks out of wheels. This type of clock was first used in church bells.

In that case a heavy object was attached to a wheel. As a result, the wheel wanted to turn due to the force of gravity. But this rotation of the wheel was controlled by a special mechanism so that the wheel would turn slowly. A time indicator cut was attached to this wheel. Later on such watches introduced dials.

Such clocks were installed in Westminster Hall in 1288 and in Canterbury Cathedral in 1292. Clocks grew in popularity during the Middle Ages. In 1364, King Charles V of France planned to build a clock. After 15 years, the construction of this watch was completed. It was created by the famous watchmaker Henry de Vick. It is the most modern watch of that era.

People then started using springs to make clocks to keep accurate time. As a result, the size of the watch is greatly reduced. The Renaissance began in Europe in the 16th century. During this time, many improvements were made to watches. Then the famous scientist Galileo discovered the first formula related to the properties of the pendulum. which is then used in clocks. Later in the 18th century there were many further developments in clock making.


After the trend of using heavy objects hanging on clocks went away, pocketable small watches were developed. These are known as ‘clocks’. This is the prototype of our modern watch. This type of clock was round egg shaped. That is why they were called ‘Nuremberg Eggs’. An oval case housed all the parts of the watch.

The demand for such watches is increasing day by day. Animal-shaped clocks, flowers, books, oysters, etc. are also produced as a result. In those days watches used to have very expensive parts. Pearls and diamonds were used to decorate watches. Later, cheaper ‘jewels’ were used in watches. As a result, the price of the watch decreases. Watches became readily available.

Smart Watch

The latest form of wristwatch is the smartwatch. While earlier simple digital watches had calendars, calculators, etc., the first smartwatch was introduced in 2010. Various mobile apps can be run on these smart watches. After that, various features were added to the smartwatch.

The famous Apple company has come up with their smartwatch. Along with this, smartwatches with Android operating system also appeared. Samsung, the top Android smartphone maker, has started manufacturing the Android powered smartwatch ‘Samsung Gear’. Audio-video player, camera, FM radio, Bluetooth, GPS, Internet, WiFi all kinds of technology have been added in modern smartwatches.

Smartwatch can be easily connected to the smartphone via Bluetooth or Wi-Fi to receive smartphone calls or messages. Step counting while walking, heart rate detection, sleep tracking, etc. are also being done through smartwatches these days. Almost all smartphone manufacturers these days have focused on making smartwatches. As a result, smartwatches are expected to improve in the coming days.

Clocks have served people’s needs for timekeeping since ancient times. Time and technology have changed the clock and it has become more modern. Future watches will make people’s lives easier.
