What is the difference between a chronometer and a chronograph?

Ian may be the question for many people who ask themselves the difference between a chronometer and a chronograph and the difference between them. To answer this question and say the difference between a chronograph and a chronometer, we have to say that motherfucker speaks two completely different terms. In other words, the meaning of these two standard terms in the clock, namely chronometer, and chronograph are not the same, but it is also worth noting that they are not opposed to each other. In this case, we can say that they are not only different. They are not one, but they are not opposed to each other, and in this article, we want to tell you more about these two terms and their differences and meanings.

It is essential to know that the term stopwatch is used to measure the watch’s performance. In other words, it is used to check the watch’s performance. Or we can even say that the chronograph can ensure that the clock movements are based on the rules of a valid watch organization and that these movements are performed according to the standards and regulations of the clock.


However, the chronograph also refers to the function of the clock, and it can be said that the timepiece is a feature of the clock and its position. To summarize, the chronometer is used to measure the watch’s performance, and the chronograph refers to the version of the watch. For Taban to show the characteristics of a watch and say that this watch has a new feature, one must use a minute or a second.

What is a stopwatch?

The word chronometer means equipment used to measure time. In other words, we can say that the phrase stopwatch refers to the equipment and tools used to measure time. To better understand the chronometer, we must be careful about the main reason and function of the watch to know the main reason for its invention and emergence. Clocks have been created to use watches to know the exact time. As they know, based on some calculations and tests performed there, they have determined the same time and adjusted the watches accordingly so that the exact time can be determined. But it is possible that these calculations and experiments have been done a little wrong and can not show the time more accurately.

This is where the concept of a stopwatch comes into play. In other words, we can say that the chronometer is a meaning and idea that can be used to show the exact time, and the main reason for its creation and invention is to show the precise time. It is worth mentioning that the chronometer is not a watch brand. It is a concept used for all hours, and for now, it can be used to indicate the exact time.

In addition, there is an ISO 3159 standard, which is a spring balance indicator as a timer and wrist timer, which can also provide a chronometer definition.

There are some organizations that, to be able to issue some formal and neutral certifications for hours, examine them to see if they can be certified as a stopwatch or not. For example, the Besançon Observatory in France, The Glashot Observatory in Germany, or the Japan Stopwatch Institute is here to do just that. Of course, there is only one organization for watches made in Switzerland, called COSC, or Contrôle Officiel Suisse des Chronomètres.

It is also worth noting that only watches tested and approved by the COSC can print the chronometer label on their watch screens. If they do not receive certification from this organization, they can not publish the chronometer on their watches.

For COSC to certify chronometers to ten watches produced in Switzerland and print the timepiece on their watches, it first receives their watches before examining them. After receiving them, he challenges them and performs some tests on them. These types of tests are some of the static tests performed on these watches. The metal is done in five different modes and to varying temperatures in a few days. The three different temperatures used to perform this test are 8 degrees, 23 degrees, and 38 degrees Celsius.

Wristwatches or even pocket watches are tested for 15 consecutive days in different states and conditions to be certified by this organization to prove the correctness of their movement and function.

There are seven criteria in these organizations, which if the clocks have these seven criteria, it means that the clock has the conditions to print a stopwatch per hour. Here are seven criteria used to check and test watches to print a chronometer in watches:

– Average daily rate

– Average changes in rates

– Average variation in rates

– The most excellent variety in rates

– The difference between rates in different horizontal and vertical positions

– The most significant change in rates

– Rate changes in temperature

– -rate resumption

It is also worth noting that each of these tests can be performed in five different situations. These different situations and conditions are – 3 o’clock, 6 o’clock, 9 o’clock, dial-up, dial down.


What is a Chronograph?

A chronograph is an equipment that can be used to measure periods. Conversely, a chronometer was sensitive to the accuracy of the clocks and was used, but the chronograph has nothing to do with the accuracy of the watches and does not care about them.

A chronograph is a complication and an additional feature that has been added to the watch face to improve its performance somewhat. For example, we can say that the display of hours, minutes, and seconds is the same as the timepiece, which is a new feature. Whether the speed is accurate has nothing to do with the chronograph. If we want to better explain the chronograph concept to you, it is as if the chronograph is not a navigation system or car seat heater. This means that it is a new and additional feature.

Chronographs that exist today for watches are devices used to measure accurate time, and on the other hand, they can add some new and additional features to watches.

You may also be wondering if a watch can be a chronometer or a chronograph at the same time. To be able to answer this year, we say yes and no.

That is, the answer to this question is both yes and no, and we can not say yes definitively, and we can not say definitively no. To answer this question better, we respond according to the COSC. However, a chronograph alone cannot be certified as a chronometer because the chronograph is used for short-time measurements. Calculates, and therefore we can not detect the amount of time the chronograph short-time calculations. If the chronograph has a clock, it is an additional result that can be used for more accurate estimates, and the COSC does not care about the chronograph in its calculations. It does not have a stopwatch from COSC.

In short, the chronograph is an additional feature that can be used to measure short periods. A high-precision one-hour desk chronometer approved by a reputable organization in Switzerland Is inserted. The chronometer certificate on the watch indicates that the watch is accurate.
