Time, despite the fact that scientists still can not finally unravel its true essence, still has its own units of measurement established by mankind. And a device for calculating, called a clock. What are their varieties, what are the most accurate watches in the world? This will be discussed in our today's material.

What are the most accurate watches in the world?

They are considered atomic - they have very small errors, which can reach only a second for a billion years. 2nd, no less honorable, the quartz watch wins the pedestal. They are behind in a month or rush forward by only 10-15 seconds. But mechanical is not the most accurate watch in the world. They need to be started and failed all the time, and here the errors are of a completely different order.

The most accurate atomic clock in the world

As already mentioned, atomic devices for the qualitative measurement of time are so scrupulous that their errors can be compared with measurements of the diameter of our planet to the nearest microparticle. Undoubtedly, the average layman in everyday existence does not need such precise mechanisms at all. These are used by researchers from science to conduct various experiments where the ultimate calculation is required. They provide opportunities for people to check the “time course” in various areas of the globe or to conduct experiments that confirm the general theory of relativity, as well as other physical theories and hypotheses.

Paris benchmark

What are the most accurate watches in the world? It is considered to be Parisian, belonging to the Institute of Time. This device is the so-called standard of time; people all over the world check it. By the way, in fact, it does not quite resemble “walkers” in the traditional sense of the word, but resembles the most accurate device of the most complicated construction, which is based on the quantum principle, and the main idea is the calculation of space-time by means of particle vibrations with errors equal to only 1 second for 1000 years.

More precisely

What is the most accurate watch in the world today? In current realities, scientists have invented a device that is 100 thousand times more accurate than the Paris standard. Its error is one second in 3.7 billion years! A group of physicists from the USA is responsible for the work of this technique. It is already the second version of devices for time, built on quantum logic, where information is processed using a method similar to, for example, quantum computers.

Research assistance

The latest quantum devices not only set other standards in the measurement of such a quantity as time, but also help researchers in many countries to resolve some issues related to such physical constants as the speed of a light beam in a vacuum or Planck's constant. The increasing accuracy of measurements is favorable for scientists, they hope to track down the time dilation caused by gravity. And one of the technology companies in the US plans to launch even serial quantum watches for everyday use. True, how high will their primary cost be?

Operating principle

Atomic clocks are also called quantum clocks, because they operate on the basis of processes that occur at molecular levels. Not all atoms are taken to create high-precision devices: the use of calcium and iodine, cesium and rubidium, and also hydrogen molecules is usually characteristic. At the moment, the most accurate mechanisms for calculating time on the basis of yttiberium are produced by the Americans. Over 10 thousand atoms are involved in the equipment’s labor, which ensures excellent accuracy. By the way, the record-breaking predecessors had an error per second of “only” 100 million, which, you see, is also a considerable time.

Fine quartz …

When choosing household “walkers” for everyday use, of course, atomic devices should not be taken into account. Of the households today, the most accurate watches in the world are quartz, which also have a number of advantages compared to mechanical ones: they do not require a factory, they work with crystals. Their average travel errors are 15 seconds per month (mechanical errors can usually lag behind this amount of time per day). And the most accurate wristwatch in the world of all quartz, according to many experts, Citizen - Chronomaster. They may have an error of only 5 seconds per year. At a cost they are quite expensive - within 4 thousand euros. On the second step of the imaginary pedestal Longines (10 seconds per year). They already cost a lot cheaper - around 1000 euros.
