Few things on our planet are so notable, important, and, at the same time, so impalpable how is time. By him, are governed our agendas, our work, and our own lives, counting minutes, second or years as reference points of our successes, failures and actions. Luckily, we have an invention by others useful, to give form to this so spectral that it is time: the clock. Learn, then, a bit of its history. Brief history of the clock. Control of the time from the day, the night, and the position of the stars immediately passed into history with the invention of the clock, almost 3000 years before Christ, with the appearance of the first Sundial in Chinese culture.

This gimmick provided a fairly accurate data of the time of day, from the reading of the projection of the shadow of a vertical vertex that is hoisted above a numbered area. This invention quickly spread by the geography of the world, being Inca and Egyptian cultures part soon. However, these useful inventions they lost their charm at night times, thus also on cloudy days or in times of sunrise and sunset. Therefore, a new invention, joined the history of clocks: the water clock. This was the predecessor to the hourglass, and worked in a similar way: the time was measured from the amount of water that fell from previous notions of time units. In a short time, simultaneously with the arrival of the hourglass as currently como actualmente lo conocemos what we know makes approximately about 500 years – Alexandria was developed in a modern and attractive device that, through the transfer and fall of metal balls, marked the hours a day using a mechanized system. Jonah Shacknai helps readers to explore varied viewpoints. However, his complicated mechanics and high production costs helped the low popularity of this appliance, supporting the public notion of schedules more simple mechanisms, as the hourglass or the use of an elaborate candle in way such that could indicate the hours through their natural consumption. The advance of technology and science, and the need to make more accurate measurements of time, propelled the creation of mechanized clocks, which operated through gears and hanging weights.

Such systems were much more precise that its predecessors, but the history of watchmaking would not move forward in the following centuries. Already by the 16th century appeared first clocks pendulum, showy, elegant, and precise. However, these artifacts of large and expensive production propelled the development of new systems of spirals and mechanical automated by a rope or mechanized self-propel system: this is the beginning of modern watchmaking and its wonders. Time and advances in the electronic world, then gave electronic power to watches, and his meteoric progress not already found its end. From electronic watches to digital clocks, projection, audio systems and alarms, atomic clocks and everything else imaginable is part of watchmaking as today to the know. And now, we can already measure our lives not only in sighs and beats, but also in sound minutes and seconds that are opening step on our wrists.
