The Chistopol watch factory was founded in 1941 in the city of Chistopol. The equipment arrived from Moscow from the evacuated Second Moscow Watch Factory. Already in the spring of 1942, the plant began producing military devices. The enterprise worked for the needs of the front and was a closed facility. Since 1943, ChChZ began to produce civilian products, the first men's wrist watch"Kirovsky". IN post-war years The plant began the development, production and release of new models of watches “ZiM”, “Volga”, “Pobeda”, “Vostok”, “Mir”, “Volna”, “Saturn”, “Cosmos”, ship clocks, and others. Subsequently, the plant became the main supplier to the USSR Ministry of Defense, and then the “Commander” and “Amphibian” watches with a water resistance of 200 meters were created. Since the 70s, the plant began producing 24xx caliber wristwatches with calendars and automatic winding. Today the factory is bankrupt, and watches are produced by subsidiaries.
The watch was delivered with a defect: “something is loose inside and does not work”
We take the mechanism out of the case and see
balls, from the ball bearing of the automatic winding sector, they are not all here, there are 2 more balls in the mechanism itself.
We disassemble the automatic winding mechanism and remove the drum with the spring.
Remove the balance and anchor fork.
The watch is disassembled and ready to be washed. Cleanliness is the key to health, and especially for watches.
The old automatic winding sector (with a crumbling bearing) and the new one.
The mechanism parts are washed and it can be assembled.
We assemble the drum and lubricate the spring.
While checking the parts for defects, I discovered that the intermediate wheel blade was bent.
We insert the wheel into the caliper and straighten it.
After straightening, we assemble the main wheel system and check the wheel slope.
We install the drum, cam and winding clutch and winding shaft.
Cover with a drum bridge and screw it on.
We lubricate and install the anchor fork, and check its operation.
We establish balance.
We install the bushings (balance bearings and shockproof device at the same time) and secure them with lyres (three-leaf springs).
And for verification.
After setup, the watch runs great!
Many people who have sports or military watches are interested in the question: why do you need a bezel on a watch? and how to use the watch bezel. In this article we will figure it out. So what is a bezel?.
The bezel (lunette, dial) is a rim around the dial that can rotate in one (counterclockwise) or both directions. It has a minute scale and cardinal directions on it. The bezel is used in military watches (for example), and sports watches. Sometimes the bezel is decorative, that is, it is made to give a certain style to the watch and may not rotate.
How to use the bezel.
The bezel has minute divisions and a numeric value. At the 0 or 60 minute mark there is a mark in the form of a triangle or a dot colored red (yellow). Let me give you an example of the practical use of a bezel. So you came on vacation to Turkey and, of course, decided to admire the underwater world, fortunately they offer it on every corner.
You were brought to the diving station, given instructions, put on equipment and now you are a diver. Looking at your hand, you will notice a watch with a rotating bezel.
The air in the tank is enough for 30 minutes of swimming underwater. Now the time is 15:30, which means we need to start ascent at 15:55. But so that, while admiring the underwater beauties, you don’t have to keep all these numbers in your head and there is a bezel. So, we turn it so that the mark coincides with the 55th minute on the dial. Now you know when the minute hand reaches this mark, you need to end your dive. This is where I end. You can also watch a video about how to use the bezel. Good luck to you in your sporting achievements.

Although wristwatches have lost their position with the advent of modern gadgets in the form of phones, tablets and the like, they are nevertheless still in use. At the same time, many people prefer the classic look of a watch, that is, with hands, hour and minute. Well, there's something to it! We can say that this is a kind of tribute to conservatism, classic style, inflexibility of views, and sometimes even fashion. Well, in exceptional cases it is also an image! However, this article is not about that at all...
Many have heard that a wristwatch with hands can be used as a compass, but how!? Let's say more, watch manufacturers often install a ring on the case - a bezel, which should act as a compass. So, how to determine the cardinal directions and how to use this compass in a watch? This is exactly what our article is about.
Watch with compass bezel ring
In order not to be unfounded, it is necessary to show our reader which companies and how they make the bezel - the compass on the watch. We can say that this is just a visual aid to possible execution options. So the compass bezel is found on watches of such popular brands as: Casio, Seiko, Timex, Swiss military and other brands.
It should be noted here that there are also electronic compasses built into watches, but this is somewhat different from the bezel ring. In fact, when electronic compasses work, the arrow or indication immediately indicates the position of the cardinal points, but with a ring you have to calculate this yourself.
In fact, in order to calculate the cardinal directions, it is not necessary to have a bezel; it is only an auxiliary device that somewhat simplifies your calculations and can make them not only more accurate, but also adjust this very bezel in the direction of the cardinal direction. In fact, the compass bezel is a simple ring with markings that can be rotated. It itself does not indicate anything unless it is installed in in the right direction. This can even be called a kind of move from the marketers of watch manufacturers, when the compass bezel looks solid and beautiful, but there is little point in it if you do not have certain skills and abilities. About them just further...
How to determine the cardinal directions using a watch or a watch - a compass with a bezel ring
Before moving on to the process of describing the determination of cardinal directions using a watch, let's talk about what is known. Everyone knows that the sun moves from east to west. At noon, the sun will point north or south, depending on what part of the hemisphere you are in. That is, we can say the following. The sun comes from the east, then through the southeast, south, southwest and leaves in the west. All this is relative to the observing person on earth, located in the northern hemisphere. Here it should be noted that the sun moves, regularly and systematically - every day. That is, there is a dependence of the location of the sun on the time of day. The conclusion is simple, so to speak, but it is on this that the principle of determining the cardinal directions is based, that is, using a watch as a compass.
In fact, the most important thing is the fact that the number 12 is taken as astronomical noon in hours. It is at 12 o'clock that the sun should be in the south, conventionally opposite the sun. That is, a straight line is built through the points: our view is 12 o'clock - the sun.
Now, if this is so, that is, if astronomical noon corresponds to noon in the time zone, which we have been having problems with lately, then everything will work out! The greater the spread between these values, the greater the error will be!
Now let’s talk about this dependence and applicability clearly and in practice. If you point the hour hand towards the sun, and also take into account the number 12 on the dial...
That field divided in two between these guides will point to the south (northern hemisphere). This rule applies before and after noon. Unless you have to divide the other half of the dial. See an excerpt from the Seiko watch instructions.
So what is the role of the compass bezel ring? In this case, the bezel ring, as it were, fixes your mental line, which you must draw in the middle. It is simply adjusted according to it manually, that is, it is set in the middle between 12 o’clock and the hour hand directed towards the sun. That's the whole principle of the ring - bezel. By itself, until you align it along the calculated line, it will never show you the correct data, as a compass would.
It remains to be said that in some cases it is recommended to use not 12 hours, but 13, as half a day, that is, the number 1 on a clock.
Features of determining cardinal directions and using a compass ring on a watch
The first feature that can be easily guessed is that in different hemispheres we will receive oppositional results, that is, with the same accuracy, but with a different meaning. If in the northern hemisphere the straight line we calculate between 12 o’clock and the hour hand points to the south, then in the southern hemisphere it points to the north. We already mentioned this, but still.
The second feature will be that the calculation of cardinal directions, as well as the use of a watch as a compass, will be possible only during daylight hours, that is, during the day.
The third feature is that even such manipulations with the clock and determination of cardinal directions are very imprecise and depend on your location in longitude and time of year. So use your other skills to determine the cardinal directions, and confirm your guess about the position of the cardinal directions. And this article is more useful for general development and in order to still bring to your attention how watch manufacturers recommend using a bezel with parts of the world!
Continuation. Part two.
So, we've gone through the first part. We got a little tools. The places where the instrument grows have been explored. We have prepared a workplace for ourselves. And in general - while we were doing all this - we had a good walk through the air and got to know the hot spots and surroundings better. The first part involved quite a lot of movement and attentiveness when hiking - you had to SEARCH. What to look for - FSE! Everything is interesting and, to our still untrained eye, something that can be useful to us and unusual. Somewhat reminiscent of plushness. What is the result:
Tool. Which? First screwdrivers, then tweezers. These include a binocular magnifying glass, brushes, Petri dishes and needles. We got some oil. Yes, at least for sewing machines. Well there is no other. We believe that we have nothing more. NO. All. We make do with this primitive set. But without it, you shouldn’t start.
We collected carcasses of hours.
Different. Old ones. Wrist. We just collected mechanisms for spare parts.
They took indiscriminately, everything that was cheaper than the cost of half a pack of cheap cigarettes. This is their price. Half a pack of Belomor or Prima. Trolleybus fare. They shouldn't cost more. Regardless of the condition - intact or broken. There are only two criteria. The first one is mandatory - not rusty. The second is desirable - that they be assembled (all parts are in place) - regardless of integrity. Trash. Let's sort. What do we have?
Women's wrists.
- Star. Old ones. Barrel-shaped mechanism caliber 18 mm. Allegedly, in prehistoric times the French brought it to us and assembled the LIP plant. So these are all French.
- Zarya- Penza Watch Factory
-Gull- standard small mechanisms, quite old, but durable
- Glory- newer mechanisms
Many other names. All Soviet. THE USSR. Apparently the state cared about the working class - it produced watches. So that they are not late for work. Maybe.
Men's wrist watch.
- Victory. Moscow. Lighthouse. Many watches were produced under these names. We're not talking about watches. About mechanisms.
There are basically 2 types of mechanisms.
- “high” mechanism - for example 1MChZ - “Moscow”. Central seconds hand. Most watches were assembled at its base, including the famous “Sports”. They stopped when the crown was pulled out. Ersatz stopwatch. Older type of mechanism. We don’t name the technical caliber - there’s no point. It is still impossible to order parts for the caliber.
- “low” mechanism - more modern. Side seconds hand.
In both the first and second cases, different factories produced a bunch of modifications of mechanisms - with improvements, simplifications, rationalizations. Suggestions. There were also a bunch of types of exterior decoration. Satisfied the discerning consumer.
In addition, there is a complete rainbow of other watch movements:
Slava - 2 types of mechanisms, self-winding and non-self-winding. It was indicated somewhere on the Internet that it was a prototype of LIP-T-15. The French again.
Complicated watch
With alarm clock
Chronometer
For the blind
Our task is to learn how to disassemble and assemble. Then everyone will go their own way. One will only disassemble. Another will collect 50% and then - as they get bored or peacefully throw it in the trash (usually habits - vodka-dancing will overpower), others - out of anger that it doesn’t work out - hit the anvil with a hammer. Still others will calmly take it apart again, put it aside for a couple of days and try again. This is a normal form of behavior for such an unusual hobby - precision mechanics.
Let's start with a simpler direction - men's wristwatches. They are larger than women's ones. You can see them better without a microscope. An example is “low” Victory. For us it is the simplest. “High” is more difficult for the first time. The clock circuit is basically identical for all single-platinum watches. Therefore, you just need to understand and remember a few is enough simple circuits. For the first training, just sketch what we are analyzing.
Frame:
Back cover.
There are several types of back covers. The only difference is in the manner of closing.
Slamming. A distinctive feature is that usually, upon careful examination, you can find a flat into which the knife is driven in order to open it with strong pressure. In modern electronic consumer goods, a similar lid is very often practiced, but with grooves, as if for unscrewing - a good joke. If you don’t know, then at least shoot yourself - you won’t be able to unscrew it.
A flat in the glass ring. This is not a cover.
More modern solution- protrusion in the lid.
And the knife just drives in here
Screw, with a screw ring or with a thread on the lid itself.
Or so - edges are visible along the edge of the lid.
We unscrew the first option either with the largest tailor's scissors (they are tougher) or with the sharpened jaws of an old caliper. At flea markets, keys like this can often be found lying around in debris.
A branded key (purchased in the most ordinary store for modellers - models of steam locomotives, cars, etc. in Germany) looks like this.
A rather rare option in Soviet watches is a bayonet mount. It turns at a slight angle and opens.
Bayonet lock on the lid
So, the clock was opened. What we see is dirt.
A lot of dirt. We immediately say that we will not deal with rusty watches. There's no chance. Nothing can be done - everything must be changed. Install a new one or sharpen a new one. It's too early for us.
Main parts of the mechanism
I - balance.
II - Wheel system
III - mainspring (maybe two - in Slava)
IV - ratchet - there can also be several types.
What we do first - while the mechanism is in the case - lower the mainspring. If the head is preserved in the carcass and can be turned (it is worn down to the base), we try to turn it slightly towards the factory and look at the ratchet. It should turn slightly and slip a couple of teeth. This is what we need - we use a needle to support it in the retracted state and, without jerking, let the crown turn and release the spring, slightly releasing the crown between the fingers.
Immediately place at least 2 Petri dishes in front of you. Or white plates or dishes with a smooth, flat bottom. Diameter 15-20 cm. I use Petri dishes. They are easier to cover during breaks.
We take out the crown. To do this, you need to press the latch with a needle.
We take the mechanism out of the case. Sometimes this is done towards the back cover. In our case it is the other way around. The ring with glass is removed and the mechanism is pulled out to the side of the dial.
We remove the arrows
A minute in general is simple - even with a screwdriver
Hours and seconds are already a bit of an adventure. Tool - a piece was torn out of the relay (there was some kind of electric relay - the material on the contact groups is exactly what we need - hard and thin. Folded it - and there is the tool we need)
Unscrew the balance. The size (caliber) of the screwdriver must match the size of the screw.
The screw was unscrewed and how can this whole assembly be lifted? - and it usually has special grooves into which you can insert a screwdriver and separate the balance plate from the base.
We take the balance like this.
We gradually put everything into Petri dishes.
Unscrew the screws of the mainspring block. There is one trick in the watch - if the screw has many grooves, it means it has a left-hand thread.
Under the dial there is an assembly of hand wheels (I) and an assembly for winding and moving the crown from the winding position to the position for moving the hands (II) (scientifically called a remontoire). Let's sort it out.
We are filming a minute trib. This is the only unit in the watch where force is required. Pull hard enough. If we missed it, we'll repeat it. It always comes off with effort. The main thing is not to be afraid.
When disassembling the pointer shift assembly (repair), pay special attention to the spring.
It has a nasty property - it clicks and flies away in an unknown direction. There is a simple trick against this - we cover (press) it all lightly with just a finger and carefully “snap” it out from under the finger with a needle.
We put everything in a Petri dish
Now the longest and neatest part. Washing.
We take a shallow bowl. We pour gasoline there. And wash it. Brush and toothpicks. To shine. So that no dirt remains.
For small mechanisms - a squirrel brush. Tougher. For large mechanisms - alarm clocks, pocket watches - you can try soft art brushes for oil paints.
Drying: first put it on after gasoline paper napkin. I usually take a piece of heavy cardboard and place a piece of paper towel on it. So that it does not jump and jump. Select napkins and towels according to the criterion - the less lint, the better.
Let the gasoline soak in. Let's just put it there. Then we take the parts with tweezers and blow air from a rubber bulb (enema) to blow gasoline out of the holes. And so, in sequence, all the elements of the clock that lie in a Petri dish or on an improvised “drying rack”. Knot by node. What we mean is this: if you unscrew the platinum and with it - 3 screws - put them together. We consider “this is our node.” So as not to confuse screws and parts. We put them in the same places in the Petri dish. Or better yet, into a clean cup. The old one will then be washed and wiped. This is if we don’t expect to collect it quickly. Or we collect it “from the sheet” - from a napkin. But this is subject to a certain experience, skill and speed of work. Balance. While we don’t have much experience, we don’t analyze it. So we push the platinum-spiral-balance block into a bath of gasoline and simply rinse it in gasoline for a long time. Clearly this is wrong. Everything needs to be taken apart, etc. - WE DO NOT HAVE ANY EXPERIENCE YET. We'll gut it for 5-10 hours, and then we'll look at the balance. How he understands it. Read books. And do it according to wise books (if it is described in detail there).
A note about the mainspring. We don't do anything. Just wipe the outside with a napkin. We clean the teeth with a brush. We're not doing anything else for now. We'll have fun with disassembly, lubrication, assembly and spring replacement next time. No experience yet. It's difficult.
And now more intellectual work - to assemble the resulting puzzle
Everything is done in the following order:
Mainspring
Wheel system. Let's have a little fun too. We placed the gears in the lower stones. They covered it with the platinum, and then we need to move the upper platinum in all directions with tweezers until the upper axes of the gears hit the stones. A little tedious, but doable. Sometimes you can try to help the process with a thin needle to move the gears that you can reach. The basic rule is NO VIOLENCE. Everything should be done without any effort. Everything by itself “clicks” into place over time and the plate noticeably “falls” down. A clock mechanism is a rather thin thing, the forces are very small, the loss of forces during operation is also very small, accordingly, it cannot be assembled on tight fits - THEY CANNOT BE BY DEFINITION. If the upper platinum does not sit in place, the gear is not seated in the stones. Or while we were moving all this, it jumped out of the lower stone. We repeat once again - THERE CANNOT BE EFFORT! A criterion for correct assembly may be the following: slightly turn the mainspring drum. ONLY SLIGHTLY - all gears should start to turn. This is all - almost effortlessly on the winding drum.
Putting the anchor plug in place
Let's put the balance in place.
Lubricate the stones from above - from the side of the back cover. To do this, we use homemade oil dosage.
We turn the mechanism over and lubricate all the stones on the dial side. Assembling the crown mechanism.
Spring. Another adventure. We press it all with a wide screwdriver. We thread the needle into place. Springs are probably the most disgusting thing in all this work. They're galloping. And we will suffer with them a) until we train our hands and b) until we collect carcasses of watches from which we will drag spare parts without a twinge of conscience.
They put it in place. We're not breathing. What if he jumps out?
Assembling the arrow wheels. We firmly press the minute tube onto the gear axis. How? Yes, whatever comes to hand is approximately suitable. That's how we filmed it and we'll put it on. We resist. You will have to press the trib hard until it clicks.
Lubricate. What is there to lubricate - if you have assembled this puzzle - figured it out - then you will also have to think about lubrication and lubricate it yourself. The basic rule is to lubricate only with oil dosage and to a minimum. All rubbing parts are lubricated. Platinum must be dry. That's why it's a recess in the stones - so that the oil doesn't spread beyond it. We do not lubricate the stones of the anchor fork. It's too early. A microscope is needed.
We set the dial.
We put the mechanism into the housing.
Press the crown lock and put it in place. Let's start it up. Let's enjoy it. DONE!!! YOURSELF!!!

Anna LyubimovaNowadays, checking the time is as easy as looking at the screen. mobile phone. But your mobile phone may run out of charge, you may forget it at home - in this case, a good old wristwatch will come to your aid. This is an almost eternal accessory that, if used correctly, will serve you for many years. Sports and military models are usually equipped with a bezel - this device helps to keep track of time, and in some cases saves lives. Want to know why there is a bezel on a watch? We will talk about this in this article.
Bezel on a watch - what is it?
If your life is scheduled minute by minute, or moreover, the lives of other people depend on you, then the bezel will help you don't waste time and always be in the right place at the right time. This is especially true for representatives of the following professions: doctors, athletes, survival instructors, trainers, military personnel, journalists, pilots.
Especially for them, watchmakers came up with one clever feature: all models of military and sports watches are equipped with a thin rotating rim with divisions located around the dial. This is the bezel - an element simply necessary for those who know exactly the value of time.
Bezel on watch
Bezel, bezel or lunette: three names for one device
Many people and watchmakers refer to the bezel on a watch by different names: lunette, dial, or ring. In fact, all these are names for the same part - a timer. It comes in two types:
- a fixed one is a decorative bezel, which is usually decorated with rhinestones and small diamonds;
- movable - such a rotating bezel can save our lives thanks to some of its features.
The main task performed by the rotating bezel is to fix a certain time period. It is with his help that we always we'll know for sure how much time is left to complete the task.
Rotating bezel on watch
He also divided into two types:
- one-sided - this is a characteristic element of a diving watch, protected from accidental increase in time;
- double-sided - for all other models of military and sports watches.
Watchmakers offer a third bezel option – “watch”. This model has three equal segments and simply created for those, who needs to keep time in four hours.
Having found out what a bezel is, you should definitely find out exactly how to use it for your purposes.
How to use the bezel?
So, you have purchased a watch with this unique feature and want to know how to use the rotating bezel on the watch. It’s very simple to do this: let’s say it’s 20:00, and we need to complete this or that task in exactly half an hour. In order not to forget about the time, we set the timer so that the zero mark was placed opposite the minute hand. Done - in exactly half an hour we will receive a signal that the time has come to an end.
The bezel is a versatile device that is used by many people around the world because it has many uses. Let's look at them in order.
Rotating watch bezel hidden under glass
Application for divers
For divers, a bezel is a must! When diving, many divers are so carried away by contemplating the underwater world that they simply forget about time. If you are diving with an instructor, then it’s okay - he will show you with signs that it’s time to surface, and the oxygen supply will definitely be enough to get to land. Independent divers can only rely on themselves. In this case, a rotating watch bezel could save their life. It is very easy to use - even a child can handle it.
Rotating bezel on a diver's watch
Let's say you are planning to scuba dive, and the air supply in the cylinder is designed for half an hour. You are planning to dive at 14:20, and return to shore at 14:50. In this case, it is enough to turn the bezel so that the zero mark is exactly opposite the minute hand. Done - you can safely dive until a minute the arrow will not reach numbers 30. Now at the right time you will remember that it is time to stop admiring the fish and sunken ships and float to the surface.
Are you afraid that during a dive you might accidentally touch the numbers set and increase the remaining time under water? You can rest assured, because in such watches the movement is in the opposite direction - counterclockwise. In addition, most of these watches are highlighted in red for the last 15-20 minutes - this a kind of signal alarm, saying “It’s time to surface.”
Timer
This element on the watch is most relevant for the military, who are given an order to carry out a command within a given time. By setting the watch bezel in the opposite direction, they will always know exactly how many seconds or minutes are left to complete the command. Just put the 25 mark opposite the minute hand - you're done, the countdown has begun.
Clock with timer
However, You'll love the timer and other people. It allows journalists not to be distracted from writing an article; housewives can use it when cooking or doing household chores. And yet, it was athletes and the military who appreciated the maximum effectiveness of such watches - now they are ready to carry out any assignments and tasks in the shortest possible time.
Compass: features of determining cardinal directions and using a compass ring on a watch
Lost in the forest? A watch with a compass bezel ring will help you navigate the cardinal directions and find a way out even from an impassable thicket. From the school geography course we remember that the sun always rises in the east, moves through the southeast and southwest, and sets exactly in the west. This characteristic feature the movements of this star in the Northern Hemisphere.
If did you go in the morning into the forest and can’t find your way back, a watch with a compass bezel will help you. This is done like this: we direct the hour hand so that it is located opposite the sun. We look at the number 12 and divide the distance between the sun and the number in half. This is the south.
Watch with compass bezel ring
The answer to the question of how to determine the cardinal directions using a watch or compass watch with a bezel ring is very simple, but there are some nuances that are worth paying attention to:
- Inaccuracy - This method depends on your location, time of year and what hemisphere you are in.
- The difference between solar and local time can vary by up to two hours.
- Time of day – this calculation is only possible during daylight hours.
In general, there is nothing difficult in using a bezel compass: even a novice tourist or a lover of hiking in the forest can handle it.
Tachymeter in a watch: the ideal device for measuring speed
The most common notch on the bezel is considered to be the tachymeter scale. This device is very important for athletes who need to measure movement speed. However, the tachymeter in a watch is so convenient and functional that it has begun to be used by motorists, navigators, cyclists, and even representatives of those professions for whom it is important to calculate the productivity of their work for a given period of time. Typically, this scale contains numbers from 60 to 500 - thanks to these marks, you can find out exactly at what speed you were moving.
Tachymeter in watch
There are two varieties watch with tachymeter. This is a chronograph watch. To start them, just find the button located above the crown and press it. After walking 1 kilometer, stop the chronograph and look at the numbers on the dial - they show your speed while driving.
There is also a watch with one tachymeter. In this case, movement begins at the moment when the second hand reaches the zero mark. Having covered the required distance, look at the place where the arrow passes - this is your speed.
Keep in mind that not all models are as accurate as possible - some give an error of 15-20%. Want to know how accurate your tachymeter is? To do this, you will need to get into the car and drive exactly 1 kilometer at a speed of 60 km per hour. The tachymeter calculates the speed in this way: divide the time in seconds (3600) by 60 seconds. We get 60 kilometers.
If the tachymeter needle is at 60 at the moment when you have driven a kilometer, the error is zero, and you can safely use such a device
Some tachymeter models measure speed in land and nautical miles - required pay attention to this when purchasing a watch with this element. There are several other options for using a tachymeter:
- For athletes involved in athletics or running.
- For tourists who are used to calculating the route and the time it takes to complete it.
- For packagers of finished products (how many units of goods were packed or shipped over a certain period of time).
As you can see, having a tachymeter on your watch allows you to calculate the speed of movement or operations performed as accurately as possible.
Heart rate monitor
Want to determine your heart rate? A bezel with a heart rate monitor is a real heart rate monitor, thanks to these scales on the outer rim of the watch you can find out the following data:
- control of heart function;
- load analysis;
- measurement burned for training calories;
- determination of pulse and its frequency.
This device is simply irreplaceable during cardio and interval training. It is considered ideal if during sports your heart rate does not exceed 60-70 beats per minute.
Heart rate monitor in watch
Count pulse according to this watch simple: the moment the second hand stops at 0, we begin the countdown. Has the arrow approached the same value on the dial? We stop - this is the frequency with which your heart muscles contract per minute.
World time
If you notice GMT on your bezel, this means you can now see what time it is in the world. different countries peace. These watches usually have a twenty-four hour scale and the dial is equipped with two hour hands. Using them is simple: set the dial to the time zone that interests you - now you, sitting in St. Petersburg, can know what time it is in London or Germany.
GMT in hours
Telemeter
As a child, all boys dream of a real commander's watch - this is indeed an unusually cool model. If you want to easily determine the distance to the sound source, then the bezel is on this will help you for hours do. For example, you want to know how far from you lightning struck, or a clap of thunder occurred. At the moment of the flash, we set the second hand to 0, and at the next flash we look at the arrow again - this is the distance that separates you and the source of the thunderstorm front.
Telemeter in watch
Logarithmic ruler
In essence, this is a device that allows you to perform certain mathematical operations: division and multiplication, raising to various powers, calculating logarithms and square powers, composing trigonometric equations and logarithms.
Typically, such watches are decorated with two lines: on the bezel and on the dial. Using them is very simple: turn the bezel until it matches the mark you want on the dial. For example, you need to divide 120 by 3. In this case, the number is 12 (aka 120), located on the outside scale, set opposite the number 30 (it is also equal to the number 3) on the inner scale. We look for the result on the internal scale, opposite the number 10 - we got 40.
Slide rule watches allow you to easily make calculations in almost all measures of length: nautical and land miles, kilometers and American miles, Latin and English. Such a device is rarely used in everyday life, but is simply necessary for pilots and sailors, as well as for those who need to calculate fuel consumption while traveling.
