Researchers believe that when the earth became suitable for human habitation, they began to try to calculate the time and the nature of life. The wild nomads of that time also tried to keep pace with the times. Getting to work in the daytime when the sun rises and taking shelter in a safe place at night became like a daily routine. Then he would try to understand how late it was when the morning light came on. Thus, day by day, people's demand for the invention of the watch began to grow.

Contents hide 1 The ancient method of counting time 1.1 Sundial 1.2 Episode 2: The Clock and its Discovery Episode 2 Watch Photo: Wrist Watch Experts believe that mechanical or other means of time tracking first appeared in the southern region of Mesopotamia in ancient Egypt about 5500 years ago. Traditionally, the creation of various types of sundials, hourglasses and water clocks over thousands of years, the knowledge of these instruments soon spread to the Mediterranean, helping to expand civilization through the Greek, Roman and Persian empires. Hundreds of years later, from candle watches, incense watches, oil-lamp watches, simple gear watches, astronomical watches to today's smartwatches, everything is a continuous evolution of ancient clock civilization. Clock came from the Latin word ‘clokka’ only 600 years ago. According to some, the word ‘clock’ is used instead of the English word ‘daegmael’ (meaning ‘counting the days’). According to another group, the word clock came from the French word ‘cloche’ (meaning ‘hour’) in the fourteenth century. Although no specific person has been named in history as the discoverer of this valuable discovery, many ancient relics and documents from ancient Egypt, ancient Greece, and ancient Roman civilization have been found. Table Watch Photo: Table Watch Six thousand years ago, in the ancient Egyptian Empire, all days were divided into 12 hours. Similarly, in 2600 BC, the Chinese shared time in the same way. This method of dividing day and night into 12 hours was also common among the Greeks. The first equal hour clocks were introduced in the thirteenth century AD. The Egyptian mathematician Abu Hasan also introduced this practice. He divided the first day into 12 equal hours. As a result, a total of 24 hours were introduced day and night. Then gradually the development of technology led to the emergence of various types of watches. From that ancient sundial to today's modern smart-watch. Experts have done a lot of research to find out that the sundial can be identified as the ancestor of the clock according to the ancient history. Because, according to them, this is the first mechanical clock in the world. The idea is that there are no approximate thorns, no ticking sound. But time is of the essence. The clock is a time indicator with a pointed disc and a spot on the round disc, with the sundial. However, the use of sundials started a long time ago. It is thought that the Egyptians were the first to make a natural clock, the sundial, and the Europeans invented the first mechanical clock based on this theory. But clocks made in the 14th century could only indicate hours, not minutes or seconds. Moreover, the current clock had two hours a day as that clock, which means that the clock could only rotate 360 degrees at a time twice a day. In other words, with this clock, the time could not be calculated completely accurate and precise. Finally, in 1757, the Dutch astronomer Christian Heisen came up with a highly accurate mechanical clock that showed seconds, minutes and hours. Ancient method of calculating timeSundial A type of time calculator called a sundial has been used for a long time. The first natural clock, the sundial, was made in Babylon, which was later improved in ancient Egypt. The sundial or (sundial) spread to the empires of Greece and Rome and underwent tremendous development, moreover its size became smaller. Experts say that the use of watches first started with a sundial or sundial. It is unknown at this time what he will do after leaving the post. The oldest known sundial, however, was made in Egypt around 150 BC. Sundial Photo: Sundial Clock Ancient Egyptian civilization dates back to about 3500 B.C. Was formed. At that time the only means of determining time was the light of the sun. They divided the day into 12 parts and determined the time based on the speed of rotation of a wooden shadow. This method is called sundial or sundial method. The structure of the sundial is very simple. It has a long fork or pointer. It is attached to a dial in such a way that the shadow of the thorn falls on the dial. The dial is marked for different hours and minutes. At different times of the day, the shadow of the thorn would fall on different places of the dial. Time was determined from this shadow. A sundial is a technique that determines time by determining the position of the sun. Commonly designed sundials, such as the horizontal sundial, often have a thin rod with a sharp edge as a time-determining style. Sunlight casts a time-determining style on the clockwise lines on the surface of the sundial. As time goes on, as the sun moves west along the sky, the shadow of the time-directional style also stays with it in different clock lines. In order to determine the exact time, the sundial must be aligned with the axis of rotation of the earth. In most designs, the time-determining style must be celestial northward (celestial north pole means north as a star, celestial north and magnetic north are not one). Therefore, the horizontal angle of the time-determining style must be equal to the geographical latitude of the sundial. The sundial method was playing a very effective role then. But the problem is in determining the time in the dark of night and on a cloudy day. That is why the astrologers started another alternative method by observing the movements of the moon and stars in the night sky. The procedure was much like this: Sundial Clock Photo: Old Sundial Clock A certain hole was made along a certain star by making a few holes in the middle of a round bowl. Other holes could be used to determine time from the positions of certain stars. This method is mentioned in ancient manuscripts recovered in the 16th century. In ordinary cheap but eye-catching sundials, the hour-angles are not perfectly accurate, so it is not possible to determine the exact time with their help. Yet in the 14th century, Europeans invented the first mechanical clock based on this theory. Even the use of sundials has not yet taken off. This sundial was in vogue in many countries of the world. This sundial used to be huge in size starting from small. There were some small sundials that people could carry around in their pockets or in their hands. Some giant sundials were made on the side of the road or in the park. So that people can easily know the time. For example, a giant pointed rectangular pillar called the Luxor Abelix in Paris is a sundial. Later, in 1361, the Muslim scientist Abul Hasan applied the formulas of trigonometry and geometry to the modern version of Sundial. The region where the old sundial watches were made, Egypt and Babylon - these are all in the same region. And because of the location of this region, the shadow of the sundial would continuously move from west to north and east with day. That is, the darker the day, the darker the night, and the darker the shadow. From there came the matter of the clockwise direction. Abul Hasan was the first to place a fork in the sundial at a certain angle, with which the hour and minute could be determined. In this way the work of looking at the clock using daylight was going on. But due to some problems with the watch, people are trying to invent a new watch. One of the main problems with the sundial was that it could not be used at night. Besides, this watch would be out of order even on a cloudy day. So in the eighteenth century the use of this watch gradually began to decline.
