In the Greek. This language is where the etymological origin of the word that we now want to analyze in depth: chronometer. And it is that it is made up of two Greek components:
• "Chronos", which was the name of the Greek god of time.
• “Metron”, which can be translated as “measure”.

A chronometer is a clock precision which is used to measure fractions of weather very small. Unlike conventional clocks that are used to measure the minutes and hours that govern everyday time, stopwatches are often used in sports competitions and in the industry to have a record of shorter time fractions, such as Thousandths of a second .
For example: "When the Jamaican looked at the stopwatch, he smiled: he had set a new world record", “I like to jog with a stopwatch to try to improve each of my brands”, "In our factory, stopwatches are essential, because if we take a second we can lose thousands of dollars".
In addition to sports events, it is also necessary to use the stopwatch in other cases. Thus, for example, it is common for it to be used in certain board games that require participants to have limited time to perform a function or even for the judges of the Record Guiness Books, in various cases.
All this without forgetting that they are also within the marine environment. In this case, we would have to talk about the so-called marine chronometers that are identified because they are on ships, because they have extreme precision and because they have the function of carrying out a fundamental mission: to determine the exact time. And it is only in this way that it will be possible to calculate what would be the exact geographical position of the vessel in question.
Usually, the stopwatch starts working when the user presses a button . The mechanism, in this way, starts counting from scratch. When said button is pressed again, the stopwatch stops, showing exactly the elapsed time.
Most chronometers allow you to measure different time periods with the same start but different endings. This allows registration successive times , while the first measured time is still recorded in the background.
The most advanced chronometers are activated and stopped with some automatic mechanism, without a person I must press a button. Different types of sensors allow to start and end the time taking with an accuracy impossible to achieve if it was registered manually. An example of a high-precision chronometer that works with sensors is the one used in athletics tests.
With the advances of the technologies we have to make clear that much has evolved within the chronometers sector. Thus, these have not only been perfected but have also seen how online models appeared that were online. Not forgetting that now all smartphones also incorporate their own.
