Wall clock began to lag behind. Surface of quartz watch
If Quartz is so remarkable, you may be surprised, then why do not keep the quartz clock time with real-time accuracy forever. Why does he still lose seconds here and there? The answer is that the quartz vibrates at a frequency somewhat different and at various temperatures
and pressures, so the victims of His abilities of the timing is a tiny trouble in warm and, in cooling, changing around us. In theory, if you hold the clock on your wrist all the time (which is at a temperature, more or less constant), they will hold better timeThan if you keep them elsewhere (as a result of which the temperature changes each time). But even if the quartz crystal can vibrate at the frequency of constant, on the chip, tiny imperfections of earth, friction, and therefore, you can enter errors in timekeeping minutes. All these effects must be introduced to inaccuracies, until the second day in hours. Typical quartz and clock (keep in mind that the second loss can be one day and be compensated by the second and in the next day, so full accuracy can be as good as a few seconds per month).
It is important to remember that Piezocharts: will vibrate when you bring electricity to it, or it will give electricity when you make it vibrate. The quartz generator uses piezoelectricity in two ways: at the same time!
I have a scheme composed on it it looks like a quartz crystal separately from the microchip scheme, but, in fact, it is a personal part of the printed crystal and two electrodes wired in it. You can clearly see them in the photos of the inside and should look and take pictures of the generator itself: they are both silver legs stick out of the metal of the cylindrical shape. Basically, this is a quartz generator, but another component of the chip wired to a chain as a resistor or capacitor.
I say "chain", but it's just thinking about the oscillator within two separate chains, as on the same microchip. The first contour (we call it input) stimulates the quartz crystal with electric flares. Feeding electricity in quartz makes vibration (or, if you prefer, fluctuate or resonate) through what is sometimes called the reverse piezoelectric effect (where electricity produces vibrations). The oscillator is configured, the quartz vibrates 32768 times per second. But remember, now a normal piezoelectric effect: when a part of quartz vibrates, it generates with electrical voltage. The second microchip scheme feels "output voltage" (presumably 32,768 times per second) and divides the frequency of receiving pulse once per second to control the engine to turn the gear. I look with a digital display, instead of transfer, the chip repeatedly divides the generator frequency to drive the clock, minutes, seconds (as shown in the figure).
Quartz generator, divide binary, counters and displays to typical Timex digital clock with USA by patent 3,863,436.
Work: As a digital quartz generator manages an hour and a minute of time display and flashing colon between them ("0:32") to specify seconds. The oscillator (yellow) vibrates 32768 times per second. Binary divider (blue, left), 15 times to create 1 Hz (one per second) of the pulse that controls and flashes. 1-Hz Signal from the divider for about 60 minutes and another 12 hours. Serves signs of a set of drivers (red) that the power of parts in the digital display.
When the crystal vibrates, it produced a piezoelectric tension. This was detected using the second set of electrodes (attached to another part of the same crystal) and is fed in the output chain. When quartz miniature technology for use in compact wristwatches, it became clear that smaller generators were needed, and there was no place for two pairs of electrodes. That is why modern generators use one pair of electrodes to stimulate both crystal with energy and detect their vibrations.
This is as much as I am going to tell you. If you want to learn more, you would like to look at the following sources. I warned that they are complicated and difficult to understand if you have some knowledge of electronic technology, then forward.
In one of the early types of quartz generator, quartz crystals had two sets of electrodes located on it. The first set was connected to the electricity input circuit and is fed in a crystal to make vibration. When shaking the crystal, a piezoelectric voltage occurs. It was noted the second set of electrodes (stuck with some of the same crystal) and is fed in the output chain. When this is used in miniature quartz technology in compact wristwatches, the need for small and oscillators is obvious with one early form of a quartz generator, a quartz crystal was two sets of electrodes installed on it. The first set was connected to the input chain and fed the electricity in the crystal to make it vibrate. When the crystal vibrates, it produced a piezoelectric tension. This was detected using the second set of electrodes (attached to another part of the same crystal) and is fed in the output chain. When quartz miniature technology for use in compact wristwatches, it became clear that smaller generators were needed, and there was no place for two pairs of electrodes. That is why modern generators use one pair of electrodes to stimulate both crystal with energy and detect their vibrations.
"Works like a clock" - is it true of this expression? After all, with time, the clock, like any device, can knock down their turn. For each type of mechanism, this may be separate causes. And before carrying the thing to the master or knock on them and shake, find out in order - why the clock is knocked down.
Why drive mechanical clock.
This view of the clock is characterized by a clockwork mechanism that needs to regularly start. In addition to the cessation of the spring plant, in most cases, the cause of the failure is simple - clogging of the device. On his small details, dust constantly accumulates, which prevents accurate hours of hours. Therefore, every 2-3 years, the mechanism should be cleaned and lubricated. To do this, the easiest way to pass the clock into the workshop, although this procedure can be done on your own.
Another inevitable force acting on the clock mechanism is the attraction of the Earth. It is considered normal slowing down the course of 20-30 seconds per day. However, a special device was invented to minimize this error - the tourbillon (see ""). It is commonly used in expensive prestigious clock models. During the period of the mechanical clock, the clocks with the tourbillon were the most complex products of watchmaking, akin to the masterpieces of jewelry skill. After all, this small detail compensating for the influence of world gravity, brought humanity to victory over the earthly attraction. But even the most expensive mechanisms have the accuracy of the course of up to 5 seconds per day.
By the way, the mechanical clock cannot be brought to the magnet. After such interaction, the clock will stop forever and repair is not subject to repair.
Why quartz watches are knocked down.
Quartz watches are characterized by high accuracy of the course, their accuracy is higher than the mechanical clock. The reason for the failure of the quartz mechanism can be inhabited by moisture or blow (with the exception of moisture-resistant and impact-resistant), which often damages the chip. In this case, the campaign to the master is inevitable. The failure occurs due to the battery wear. Usually not immediately, at first they lag behind a few minutes. How to replace the battery knows each.
In addition, quartz wristwatches are easily knocked down when the static electricity is hired. For example, when the interaction of a woolen sweater or any synthetic thing with a human body arises a discharge. It is transmitted when changing the chronometer and resets the testimony. To avoid such a phenomenon, you just need to shoot the clock with your hands before the sweater or another thing.
Why the electronic clock is knocked down.
Electronic wrist watches are knocked down in the same cases as quartz. In addition, these type of chronometer as any other electronics vulnerable to magnetic fieldwhich is created when working around us household appliances. This effect is so large, which leads to a violation, and sometimes to a complete stop of the clock mechanism. Therefore, you should not put the clock on the fridge, TV or microwave.
Esoteric look.
The esoterica adherents talk about the influence of a person's biofield to work the clockwork. So, the clock Being for a long time on the hand of a man seemed to adopt his energy and continue to follow its biorhythms. And without human energy, the clock moves weakens or stops at all. Witnesses argue that they stop after the death of their owner. And at the same time clarify: it happens with a clock on a bracelet from natural material - leather or metal.
Those who are important time accuracy is worth thinking about the acquisition of a binary mechanism. Of course, this is not an "eternal engine", but failures in the work of such hours are much less likely than other models.
"We treat" Chinese watches "Chinese pills."
Experience unsuccessful purchase. The defect that can be corrected. Is it possible to call this overview? I think not fundamentally. The clock is not my topic. Therefore, the great request of large stones is not to throw. Per seld advice I will be grateful. I ordered this watch at the request of a comrade (we work together). He chose, I ordered. Clock inexpensive and appearance I liked. I read reviews about the seller, everything seems fine. Ordered ...
Reached in 15 days. Let's see what came. 
Packaging is not bad. Therefore, everything came out "in wholeness and safety." 
The backlight is also cool. 
There is a stopwatch. In general, everything is standard, there is no need for a particularly listed. There were many reviews of inexpensive hours.
But the review started not because of this. I decided to see how accurate. Opened accurate Moscow time on the Internet. I set the time ... after a day I checked. Survived seconds for 50. This did not expect even in a "drunken dream." Chinese watches purchased for 22 rubles in our city are running away for 50 seconds somewhere in the week. And these per day. It's about how I lied (really did not understand at what stage).
And now proceed to the main part of the review.
I will try to cure this watch, sort of like on me part of the guilt. I made an order, I received in the post office, I presented the owner too.
Broken electronic watches none did not throw away. Many space do not occupy. As I knew that we would fit. 
Chose Montana. They served me faith and the truth for many years, until they got under the rain. Put with all melodies immediately ... and died.
First you need to disassemble the "sore clock" and eliminate the defect. 
The arrow is indicated quartz, which I will change. Everything turned out to be much easier than thought. Dropped, hit a new one, gathered. Everything is working. Now they do not run.
That's all! In the role of "pills" quartz from Montana. As already wrote repeatedly, there are at least two outputs from each situation ... I found one way out.
The second part of the review was for those who are friends with the soldering iron and are not used to surrender. Perhaps someone uses this information. By the way, the clock is embedded in hygrometers and table thermometers ...
Good luck!
The clock is an excellent accessory that has not lost its relevance even to the century of computer technologies. With their help, we arrive at business meetings on time, do not be late for work, we manage to take the children in kindergarten And we always know how many minutes left before the long-awaited meeting with a loved one. Simple wall or antique outdoor, mechanical or quartz - similar time meters can be found in every home. But even the most accurate mechanism from time to time is knocked down, and then the clock starts to deceive us: That will show more time, less. As a result - missed meetings and finding a job. Let's find out why the clock is rushing and how to fix this situation.
About the accuracy of hours
Many people think that the term "accuracy of the clock" means how far they are shown. Watchmakers believe that the accuracy of the course is the inevitable deviation of the clock from the exact time. As a rule, such measurements produce once a day. There is even a special table of permissible deviations for different types Hours:
- mechanical clocks can hurry or be late for 30-60 seconds;
- quartz - for 20 seconds;
- clock with chronometer no more than 5 seconds.
Of course, even the most accurate clock is sometimes They fail - in most cases it is enough to twist them until the exact time. If the clock is constantly deceiving you, showing the wrong time, then it's time to turn to the watchmaker and eliminate the cause of the breakdown.
Hurry up hours
The clock began to hurry what to do?
It is worth starting with the fact that in all the mechanical clock there is a small spiral. The degree of voltage and the frequency of oscillations in it is constantly changing - the lower the frequency of oscillations, the greater the inaccuracy of the stroke. It is not necessary to think that it is characteristic only for Soviet models - modern mechanical o'clocks can deceive you by 1.5-2 minutes.
Let's figure out what other times may be the causes of inaccuracies:
- Reaction to temperature differences (heat, humidity, severe frosts).
- The degree of strain and blooming spring.
- Thickened lubricant.
- Hand position. If a she is lowered all the time, then the time on the clock will be a couple of minutes more than in fact.
- Reaction to changes in the gravitational field of the Earth.
There is one very an important rule: The spring the spring is less, the faster the clock go!
If your time guardians started in a hurry, do not try to eliminate the breakdown yourself. Here you need an easy eye and accurate knowledge of the reasons. An experienced watchmaker will fix the cause in just a couple of hours, and you risks them to finally spoil.

Hurry up hours - anomaly, warning or banal malfunction?
Our ancestors believed that the serviceability of hours is directly related to the life of their owners. So, if you are unhappy with yourself And what is happening with you events, then the clock will go wrong. Only one thing can be corrected: Move the order in your thoughts and soul, then time will make friends with you.
The more bustle and experiences, the more problems you try to solve at the same time, the more your watch will be lagging behind
These little long-term keepers persistently react to your experiences: you should fall into depression or think about that in your life everything is bad, how the clock is beginning to be upset. There is a proverb: "You do not observe happy hours." It has a double meaning, one of which lies in the fact that when in your life everything is spread over the shelves, the clock is working properly.
If your rods are constantly late, then - you looked at the past, and you need to start urgently life with a clean slate. The clock is a kind of prompt that signals: Urgently change and change everything around!

This option of hours can be found in every home - many models have been preserved since Soviet times. Such instances will serve you for many years, but they can show inaccurate time. For example, the watches of the East then and then seek to escape forward - it is fixed only by specialists.
Watches East
The clock is a very gentle mechanism requiring care and accurate circulation. They are worth it take care of temperature dropsextreme situations and high humidityBut there are several more reasons why they start buggy:
- Small housing. A small balancer and spring spring spring slow down the spring energy, hence the cloves of the clock.
- Friction prevails over the balance sheet energy. Hence the rapid wear of spare parts and a slow motion.
The answer to the question of what to do, if you hurry a mechanical clock, can only be one - contact the repair shop. The watchmaker will clean and adjust the length of the balancer, will replace faulty parts, lubricates watch details of oil. After such a repair, your rods will serve you for a very long year.
We hurry a mechanical watch
Why do electronic hours start to rush or fall behind?
The basis of such functions is a clock generator: this is a small chip, which gives the impulse once for a while. Many watchmakers tried to solve the problem of faults in them, but to fix if the electronic clock is rushing, something inside this mechanism is almost impossible. In any case, they will slowly lag behind or hurry.
Caused by two things:
- The inability to create an ideal accurate chip - the error will necessarily be let and in a fraction of a second.
- Changing the internal parameters is a decrease in the capacitor capacity, the trigger time of the transistor shutter.
In this case, it makes no sense to carry the clock in the workshop - electronic options are inexpensive, and it is easier to spend money on buying new hours.
Hurry up electronic hours
Wall clock mechanism and testing of wall clock accuracy
If you are the possessor of a simple version on the batteries, then fix the breakdown is simple - it is enough to replace the battery to a new one, and they will show the exact time again.
It is much more problematic if you hurry a wall clock with an auto-shift - in this case, you can try to fix them yourself. The mechanism itself is very simple, and it can work without interruption for about three years.
Three years later, from the moment of purchase, carefully clean the clock from dust and dirt, and then lubricate the thin layer of oil
Failure to accuracy can occur also due to the fault of special hammers, which hit the springs of the battle. While the springs are headed, the accessory shows the exact time. However, it is very easy to fix: it is enough to turn the minute arrow along the move of its movement, and the classes are working again.
Do not want to spend time on your own repair or just afraid to damage such a fragile mechanism? Take away clock in repair shop - There they will quickly return the perfect accuracy.

Quartz watch
Such models of the clock are much more accurate and more reliable than their mechanical fellows. Nevertheless, they can also run away or fall behind. The watchmakers allocate several reasons why the wrist quartz watches are in a hurry:
- Battery power consumption. Standard can serve about a year - as soon as it starts to sit down, the rods accelerate their pace. Avoid such a situation watch with a generator (The frequency should be at least 144 Hz): With careful operation, they will serve you for more than 10 years.
- Wear quartz crystal (than he is older, the more changes occurs in the resonant frequency).
- Drops of temperature modes.
- Use under high humidity.
- Water getting inside.
If you have a question: "Why is the electronic clock" hurry "and there was a need to repair this useful wrist accessory, then do not even try to fix the breakdown with your own hands. Only a professional can help here! In case you download cheap classes - buy new, because often the repair will cost you in the same amount as the purchase of new ones. Dear quartz watch makes sense to attribute to the workshop - good master Give them a second life.
We all prefer different hours. Some are only mechanical models. Others decorate their homes with massive clocks with a cuckoo or complement the decor with simple clocks with colorful patterns. Third and day to live can not without their quartz Khodikov. Regardless of the variety, all the hours need careful care and timely repair. Independent repair can lead to a deplorable result, which is why trusting the repair is professional watchmakers.

And it's easier to buy new ones - these days in stores many models, among which you will certainly find your perfect clock.
In this small essay with photos, I will show the general public how to treat a fairly common "sore" digital electronic hours - inaccurate move. The clock can be lagging behind or hurry and most often on small stroke errors we do not pay attention, but when the watch is lagging behind 5 (five) minutes a day, it starts to annoy.
Ready? Go!
Intro
I bought this watch in order to configure the old Soviet times when the sun was greener and the grass brighter ... or vice versa? .. No matter! The main thing is that the joy did not work - the clock was gloomy behind. More than 5 minutes a day. We must treat, I thought. 
Running forward, I note that I did not open the dispute, one hundred rubles is not the money. The problem is not in the seller who sent low-quality goods. The problem in the product that the seller cannot check in no way - there will be no Chinese / Chinese woman sit and conquer the accuracy of the course?
For the treatment of hours we will need:
Before
+ soldering iron. It is desirable not very powerful, 25-40 watts are quite enough. 60 will already be too much.
+ Quartz replacement resonator. Sold or in China or in any radio market. It is inexpensive, called "hour quartz".
+ Thin crisp (phillips) screwdriver or thin flat screwdriver. Cross preferable.
Desirable
+ Tweezers with sharp sponges - take the screws (Dada, the plastic body, the frame is also plastic. everywhere screws)
+ Good lighting and stationary magnifying glass or jeweler glasses / watchmaker to see a red hat clock well.
Disassemble hours
We spin four screws holding the back cover. Gently remove the cover, remove the piezoelectric resonator (sulfting). I do not paw with your fingers, keep on the side faces and for the metal base. 
We note that there is no protective gasket in the clock, therefore water and sweat will fall inside the clock. We understand that the Chinese for the sake of cheapness save generally on everything, it means that the glass is most likely sitting on a double-sided scotch and buttons without rubber oils. So, the clock will have to be removed in bad weather and during physical work.
Take out the clock from the case. 
The housing, the back cover, the rear cover curbers and the squeeze we remove to the side.
Remove the four screws - three hold the lithium battery, 2016, one holds a foot-spring for feeding the signal to the squeeze. 
We remove it all aside. We consider fee. More screws are not visible, it means that it is good.
Gently tweezers remove the board with a plastic clip. 
Inside the clip we see a conductive gum that transmits a signal to the LCD and the LCD itself indicator itself.
Rubber fingers do not touch, for nefig. Sorink or dirt will fall, some segment will fall off on the indicator and disassemble again ... Nafig it is necessary ...
In the blue shrimp - the coil, which gives the sound. It is not necessary to touch it too. Hurt easier simple, wiring there thinner hair.
But the metal cylindrik on the legs is our quartz resonator, which must be changed.
To replace quartz, I decided to use a donor quartz with an old motherboard, which died about ten years ago and I slowly disappear on a small set. 
Quartz here is somewhat larger than in hours.
Here for comparison already drop off quartz from the motherboard and the hour fee. 
Apply quartz to the board. Suitable. We put quartz in the clip, also fits! Excellent! Change! 
For replacement simply we drop one quartz and we hit the other.
There are no polarity, no features. The procedure is simple and does not require special qualifications. 
Voila! Quartz is replaced. Align the quartz housing so that it is just below the board and did not touch the batteries.
Reverse assembly
We collect the mechanism in the reverse order - fee put on the clip, there are guide pins. At the fee put the battery, minus down. 
We wear the contact block on the battery. In these hours, it also holds the battery and is a contact group for the buttons. We screw three coarseers. Then separate contact for a squeezer. We also screw.
We turn the block and look - the clock must start. If this did not happen, it means that or turned the battery or the quartz or the quartz or it is non-working or static killed the fee :)
Well, if everything earned, carefully put the fee in the cluster of the clock, centen it so that the numbers were parallel to the edge, then we install the squeeze back, screw the lid ... 
That's it!
We won a big problem)))
During the day, the clock did not go any forward any back, go smoothly and for sure. You will also unsubscribe about accuracy.
I must say that the quartz replacement procedure is the same for all quartz watch - Digital, shooter. But it must be remembered that most Chinese quartz watches are assembled on plastic rivets, which are melted with "mushrooms", i.e. In fact, breaking the clock, collect them very problematic.
Well, the size of quartz also matters - if the quartz from the mother would not approach in size, they would have to look for another, smaller.
Out of this "Murzilki", the film remained, which the Chinese did not remove from the LCD when they put it in the clip. I removed this film and the contrast of the screen increased slightly. The film is almost not visible, but she was on my clock.
Upd.
.
For the past four days, since the replacement of quartz, the clock was killed forward for two seconds. 15 seconds per month.
For a penny watch and free quartz, I consider the result satisfactory. Personally, it is quite satisfying me)))
You can, of course, search for ferreclasses Quartz watch for a penny, to put a bunch of quartz and experiment with accuracy ... But it will leave perfects and toast frikas)))
The comments present a formulation of a more subtle adjustment of accuracy, by putting miniature ceramic capacitors. As an alternative to the replacement of quartz - is quite viable and sensitive. The main thing is to place the place where these capacitors are placed. Well, the presence of these ...
And in general, friends, the main thing is not an overview, the main comments)))
Thanks to everyone for valuable ideas and various discussions)))
