1. Before the digital age, when people didn't have mobile phones, wristwatches were the main way to tell the time. But it was not always so. Until the early 1900s, watches were not popular. Instead of wrist, people then used pocket ones. Today, pocket watches have lost their former popularity, but then, in fact, they were the only means of determining the time on the go. The first pocket watch was invented in 1510 and gained popularity in the 1700s and 1800s.

2. The first documented clock was found in Egypt. The exact time of their creation is difficult to determine, but archaeologists believe that they were made between 2000 and 1500 AD.
The Egyptians created clocks by making a stone obelisk and then placing it in a certain place so that it would follow the path of the sun. By reading the length and direction of the obelisk's shadow as the sun moved, the Egyptians could roughly tell the time. This amazing creation at that time is known as a sundial. Later, people began to make water clocks, more accurate than sun clocks.

3. Wristwatches began to gain their popularity during the First World War. It was then that they began to displace pocket ones that were not very convenient in combat operations. Moreover, many men also wore wristwatches, placing the dial on the inside of their wrist, which allowed them to see the time while holding a rifle. As more and more men began to wear wristwatches, their popularity further intensified with the end of the First World War.

4. The best-selling watch in the world is the Apple Watch. And they have been holding this leadership for several years. Moreover, the gap between Apple Watch and other brands is so huge that the “king of smartwatches” surpasses the entire Swiss industry in sales: in 2019, 31 million Apple Watch units were sold, while all of Switzerland sold only 21 million units of watches from different brands.

5. If a simple quartz watch consists of several dozen parts, and a mechanical one - just over a hundred, then the most complex watch ever created contains 2826 parts, squeezed into a "box" with a diameter of several centimeters. It took eight years to build this model. This watch was made in a single copy by order of a major collector.
