Useful functions of the wrist watch

 

Few modern people imagine their existence without such an indispensable accessory as a wristwatch. They are used by men, women and children. Their relevance remains consistently high, despite the emergence of a huge number of high-tech gadgets on the market. As statistics show, most consumers choose a wristwatch with advanced functionality. What is the benefit of such a decision? What options will really be useful in everyday life?

 

Functionality

 

Initially, a wristwatch is an accessory that measures time. But most of the models on the market today have much wider functionality. Here are the most popular and popular of them:

 

              chronometer,

              chronograph,

              tachymeter.

 

Consider each of these options in more detail, and then you will determine whether it will be useful to you personally in the operation of the wristwatch

 

Chronometer

 

A chronometer is essentially a device that increases the accuracy of calculations. It's just a feature of the mechanism. The wristwatch with chronometer has 3 dials, separately displaying hours, minutes and seconds. Thanks to this constructive solution, the arrows do not overlap each other.

 

At the dawn of its creation, such models of watches were used in observatories, but today the functionality of the chronometer as such is lost. Accessories with 3 dials are rather a spectacular element of decor.

 

Moreover, to get the title "chronometer" watch must pass the appropriate testing At the Institute of chronometry COSC (Switzerland). The accuracy of such accessories is +6/-4 sec in 24 hours. This parameter is checked at least 5-12 hours and at different temperatures in the range from 8 to 38 0C. such a check is not cheap, so only the world's leading brands can afford it. As a consequence-the final cost of production is quite high. Models that have passed the test are easily recognized by the inscription on the body of the Certified Chronometer.

 

Chronograph

 

In the literal translation from the ancient Greek language, the word "chronograph" is translated as "writing time". Today, this option has another, more common name – stopwatch. The first such watch was created by the French watchmaker Rescuecom. He developed a mechanism capable of measuring minute intervals of time with the highest accuracy. In those days, the results of measurements were noted directly on the dial with the help of ink needles.

 

The first multifunctional chronograph equipped with the function of start, reset and stop was created by Adolf Nichol only in 1862. 50 years later, this mechanism was improved by Gaston Breitling, turning it into a functional wrist model, which found wide application in aviation.

 

Modern chronograph watches differ in several ways:

 

1.            On the complexity of the mechanism. They are divided into simple and summative. It has a button that starts the measurement process and stops it. The summing chronographs also have the option of zeroing and automatically summing the values of different time intervals.

2.            By the number of arrows and the number of buttons by which they are controlled. Along with one hand, there can be 2 and 3 of them in the clock. A variant with two hands is called a split chronograph. It is used if you want to simultaneously track two events that differ in start time and duration. Three arrows-flyback. Having a clock with this option, you can simultaneously reset the results of measurements and enable a new countdown.

 

Many models of wristwatches are equipped with a chronograph. This option does not affect their accuracy, does not disrupt the operation. As an indicator, you can use either a normal second hand or an arrow placed on a separate dial.

 

Tachymeter

 

Most often, the tachymeter is equipped with chronograph watches. It is a fixed scale located on the outer edge of the dial. There are digital marks on it: "60" opposite the 12-hour mark and " 120 " under the 6-hour mark. In addition, such models of watches are equipped with another additional hand that moves independently, without being tied to the operation of the main mechanism. To start it, you need to turn on the tachometer.

 

Use this function to determine travel speed based on travel time. The result is the distance on the scale covered by the second hand when covering a distance of 1 km. the Unit of measurement does not matter. It can be measured in kilometers, meters, miles, etc. to Get the results of calculations when traveling over long distances, additional mathematical calculations will be required. Using the tachometer, you can perform reverse calculations. In particular, knowing the speed can determine the distance traveled.

 

A large selection of watches equipped with these options is presented in the catalog of the online store "best-Time". These are stylish and effective models with bright design and wide functionality.
