THE CLOCK

The clock is a machine for measuring time in hours, minutes and seconds. A source of mechanical or electrical energy is used to move clockwise through a gear wheel mechanism.

Ancient civilizations, studying the moon and the sun, because they mediate time, years and seasons, were used as a clock to measure the passage of time.

Another clock was invented, which was quite reliable, for the time, was the hourglass. This used two glass bases, which were joined by a small hole where the sand went from one compartment to another. These measured usually within one hour.

The clocks or large churches appeared about the 13th century AD, and it was not until 1524 that invented the first pocket watch. The inventor of the clock was the watchmaker Christian Huygens. And in the mid-nineteenth century invented the wristwatch as we know it today thanks to the inventor Patek Philippe.
