The water clock is one of the ways in which ancient people use to see the time without work is simple, leave the water drips into a container, which is gradually making mines inside floating along the bezels. Watch the oldest discovered in the tombs of the Pharaohs 1 tape colonels (Amenhotep I) Watch the first cog Island (escapements) has not occurred, even the year 1285 Island Cog is a mechanism which moves with the rhythm and pushed forward with gears. At the same rate. The tower clock first occurred in Milan, when there was a clock needle 1335 one is needle hours. Precision of time say it still does not consistently.In the year 1510 to devise a clock has been updated by the German Peter Hale, Martin hotels Nuremberg (Peter Henlien of Nuremberg) which devised the system clock spring. Even if this clock is more precise, but still has problems walking slowly when the spring line (the mainspring) loosen the formats of the clock has been adjusted by the Java app neck Sheikh (Jacob Zech) of Prague, which uses a pulley coil comes gravity pulling force of a spring balance, despite trying to add. Precision timekeeping device, but it also works with just a single needle needle.Chot Gerber gJost Burgi, Swiss inventor of logarithms In the year 1577 mechanic clock, nationals of Switzerland chot Gerber (Jost Burgi (1914), ๑๕๖๔-๑๖๔๒) fabricated a watch with a syringe, needle, but for the first minute, this actually does. Even with the invention of the clock with a pendulum upward in the year 1656. The early 1580 inventor nationals Italy Galileo Galician Lake (Galileo Galilei 1564-1642-1965), an observant and Superfast inspiration to devise the first pendulum clock was found that stroke of the pendulum swing is equal to the number of time. He and his son Vincenzo spring (Vincenzo ๑๕๒๐-1965-๑๕๙๑) started the design and find the most suitable template by such a principle. But ultimately unfortunate students will have created a clock based on a template idea. Galician Lake Oakland and secret fall ill and die. However, according to Galileo's sons. Don't let the vision of father passed by wasteland and invention prototype built in 1649.The Galileo Galileo's ideas were developed, in the year 1656 by chen Hu dat Christian peasants of maths (Chirstiaan ๑๖๒๙-๑๖๙๕ (1914), Huygens) who think a weighted pendulum clock, walk up a needle first. This makes an attempt to preserve time on the watch is accurate. At any time possible. Although the clock will still work with single needle system physically enough, the year 1680 hands appear up on the watch face.Quartz watches.In the year 1889 kamun cheese. Oval FIR (Siegmund Riefler) have created a precision pendulum clock within one hundredth of seconds. Causing artificial clock that uses a pendulum followed two consecutively in the year ๑๙๒๑ by w. h. Chot (W. H. Short this clock with a pendulum pendulum works by secondary. A thousand quarters of thiang seconds per day. While quartz movement (quartz) began to replace the pendulum clock in the past decade, ๑๙๓๐ and ๑๙๔๐, but it also has been used in the current pendulum clock. Because the model is a grandfather pendulum clock of interesting old accumulation. Quartz is a work based on the properties of the glass causes. When placed in a magnetic power Glass crystals would change shape, vice versa. When squeezed or broken glass to get power back airport as well. When removing the glass crystal is connected to an electrical circuit that reaction occurs, it will cause the crystals. The glass shaking. Born into a continuous spectrum of work because the watch is correct and the price is not high. Quartz timekeeping device became the first people. Even though a lot of popular nowadays, but the precision of quartz movement is falling as the clock Atomic (atomic clock) which has a very high precision.
