The history of the discovery of the clock-sunglasses: it is the first mechanical watch. Its origins in Egypt and Babylon approximately 5,500 years ago. It still survives. Do not cut seconds and minutes, no tick sound. But the time is absolutely perfect. A pointing spell and a spell of time is the time of the sunlight. Only seven hundred years ago, the Latin word 'Clock' came from Clock. Callacca means bell. However, in the history of this particular invention, the name of a specific person is found Do not go. However, the use of the sun watch has started long before. It is believed that the Egyptians created the first nature-built sun-clock, and in the 14th century, Europeans invented the first mechanical clock based on this theory. But in the 14th century, the clock was able to indicate only hours, could not determine the minutes or seconds. Besides, two hours of the current clock was one day, which means that the clock could rotate only 360 degrees in a single day. That means that this clock was not fully accurate and could not be calculated for the exact time. In the meantime, the Dutch astronomer Christen's Hygiene came in 1657 and designed a perfect mechanical watch that accurately indicates minutes, seconds and hours. [3
