A watch is not only a prestigious accessory, but also a rather useful thing, which often has a lot of additional functions that its owner does not even know about. For example, a bezel for watches. What is it and how to use it? We will tell you further about this interesting and useful device.
Bezel on a watch - what is it?
A bezel, a limb, a lunette (lunette) is the name of the same element. This is the name of the rotary ring around the dial of a watch. Its main purpose is to use it as a timer.
The mechanism of the limb, depending on the model of the watch, can be either one-sided - rotate in only one direction, or two-way - rotate back and forth. For example, diving watches are equipped with only one-way mechanism. This is done in order not to accidentally increase the threshold of time during which a person can be under water.
Having figured out what it is, a bezel on a watch, let's move on to the most interesting - where and how to use it.
Application for divers
Most of all, limbs are important for diving enthusiasts. It is an important component of the safety of divers, as it “remembers” the limit of time that can be spent under water. Therefore, it is one-sided - we have already mentioned this.
How does this work in practice? You plunge under the water at 8:30. There is enough air in your tank for exactly 20 minutes. Turn the selected triangle on the limb to the mark of 10 (this is 8:50). Now you do not need to keep the time of return in your head - only from time to time follow the arrow approaching the mark of the lunette. If you accidentally displace the bezel, the time threshold will only move down.
Tachymeter
If the numbers from 60 to 400-500 are engraved on the dial of your watch, then what is it? Is it a bezel? On the watch in front of you is a tachymeter scale. It helps to calculate the average for any recurring event. With the help of a tachymeter you will calculate the average speed of a car, the productivity of your labor for a certain period of time.
World time
Your bezel may also be GMT (Greenwich Mean Time). He in this case has a twenty-four numerical scale. The dial at the same time with two hour hands. A great example of a model with such a bezel for watches is Vostok-Amfibiya. Adjust the position of the limb so that it reflects the time in the time zone that you need. So, for example, you can, being in Moscow, know what time it is in London.
Heart rate monitor
Such lunette is installed on special, “medical” watches. You can recognize it by calibration in 15, and sometimes 30 units. Start counting the beats of the pulse at the same time as the second hand approaches 0. As it approaches the indicated number on the limb, stop. Now you know your heart rate per minute.
Telemeter
This bezel function is most characteristic of the so-called commander’s clock - this is a scale that helps determine the distance to the sound source. But for the sake of experiment, with its help you can determine how far from you lightning struck. To do this, at the time of flash, set 0 bezel on the second hand. When the thunder strikes, look again at the arrow - on the telemetric scale you will see the distance to the thunder front.
Logarithmic ruler
The function is of little use in everyday life. Hardly anyone is going to solve complex logarithmic problems with a wristwatch. However, it is indispensable for professionals who need to make such calculations on the fly - for pilots, employees dealing with navigation.
Compass
To use the limb as a compass, you need to brush up on school geography. So, at noon by the sun, you can determine the location of the north, if you are in the south, or south - in the opposite situation. To do this, point the hour hand at the star, and set the bezel triangle strictly in the middle between it and the number 12 on the dial. That's all, you have found the direction of the desired side of the world.
Timer
The watch is 15:40, but you promised to call a friend in half an hour? Just set the limb triangle to 10 (16:10) and go about your business further. Just do not forget to glance at your watch from time to time.
Decoration
Bezel on a watch - what else? Of course, a stylish decoration. Manufacturers often arrange it with intricate engraving, inlaid with precious metals and stones, give an unusual shape. Sometimes interchangeable dials come in the kit in order to change the appearance of the accessory in accordance with your style.
Thus, we were convinced that the bezel is not only a decorative insert on a watch, but also an element that performs a number of interesting and useful functions.
