In this short essay with photographs, I will show the general public how to treat a fairly common “sore” of digital electronic watches - inaccuracy. The clock can lag or rush, and most often we do not pay attention to small errors, but when the clock is behind by 5 (five) minutes a day, it begins to irritate.
Ready? Go!
Intro
I bought this watch to be nostalgic for the old ones. Soviet times, when the sun was greener and the grass was brighter... or vice versa?.. it doesn’t matter! The main thing is that there was no joy - the clock was disgustingly behind. More than 5 minutes a day. I need to heal, I thought. 
Looking ahead, I would like to note that I did not open a dispute; one hundred rubles is not the same money. The problem is not with the seller who sent a low-quality product. The problem is in a product that the seller cannot check in any way - surely a Chinese man/woman will not sit and measure the accuracy of the move?
To treat the clock we need:
Necessarily
+ soldering iron. preferably not very powerful, 25-40 watts is enough. 60 will already be too much.
+ replacement quartz resonator. Sold either in China or in any radio store. It is inexpensive and is called “watch quartz.”
+ thin Phillips screwdriver or thin flat head screwdriver. cross is preferable.
Preferably
+ tweezers with sharp jaws - pick up the screws (yes, the body is plastic, the frame is also plastic. There are screws everywhere)
+ good lighting and a stationary magnifying glass or jeweler/watchmaker glasses to clearly see Little Red Riding Hood's watch.
We disassemble the watch
Unscrew the four screws holding the back cover. Carefully remove the cover and remove the piezoelectric resonator (tweeter). We do not paw the squeaker with our fingers; we hold it by the side edges and the metal base. 
We note that the watch does not have a protective gasket, therefore water and sweat will get inside the watch. We understand that the Chinese save on everything for the sake of cheapness, which means that the glass is most likely sitting on double-sided tape and the buttons do not have rubber seals. This means that the watch will need to be removed in bad weather and during physical work.
We take the watch out of the case. 
We put the case, back cover, back cover screws and tweeter aside.
We unscrew four screws - three hold the 2016 lithium battery, one holds the spring tab for sending a signal to the tweeter. 
Let's put this all aside. We are considering the fee. You can't see any more screws, which means that's good.
Using tweezers, carefully remove the board from the plastic holder. 
Inside the clip we see a conductive rubber band that transmits a signal to the LCD and the LCD indicator itself.
We don’t touch the elastic with our fingers, because it doesn’t matter. If a speck or dirt gets in, some segment on the indicator falls off and you have to take it apart again... what the hell...
In the blue heat shrink there is a coil that produces sound. There is no need to touch it either. It’s easy to damage, the wiring there is thinner than a hair.
But the metal cylinder on the legs is our quartz resonator, which needs to be changed.
To replace the quartz, I decided to use donor quartz from the old motherboard, which died ten years ago and I am slowly taking it apart into small components. 
There are several quartz here bigger size than in hours.
Here, for comparison, is already soldered quartz from the motherboard and a clock board. 
We apply quartz to the board. Fits. We put quartz in the cage, it also fits! Great! Let's change! 
To replace, simply unsolder one quartz and solder in another.
There is no polarity, no features. The procedure is simple and does not require special qualifications. 
Voila! quartz replaced. We align the quartz body so that it is just below the board and does not touch the battery.
Reassembly
We assemble the mechanism in the reverse order - we place the board on the holder, there are guide pins there. We put the battery on the board, minus pointing down. 
Place the contact block on top of the battery. In this watch, it simultaneously holds the battery and is the contact group for the buttons. Fasten with three screws. Then a separate contact for the tweeter. We also screw it on.
We turn the block over and look - the clock should start. If this does not happen, it means either the battery is upside down or the quartz is not soldered in or it is not working or the board has been killed by static :)
Well, if everything works, carefully place the board in the watch case, center it so that the numbers are parallel to the edge, then install the beeper back, screw on the cover... 
OK it's all over Now!
We have overcome a big problem)))
During the day the clock has not moved forward or backward, it runs smoothly and accurately. I'll watch it some more and then report back on the accuracy.
It must be said that the procedure for replacing quartz is the same for all quartz watches - digital, dial. But, we must remember that most Chinese quartz watches are assembled on plastic rivets, which are melted with “mushrooms”, i.e. in fact, once the watch is disassembled, it is very difficult to reassemble it.
Well, the size of the quartz also matters - if the quartz from the motherboard did not fit in size, then you would have to look for another, smaller one.
Outside the framework of this “Murzilka” there was a film that the Chinese did not remove from the LCD when they put it in the holder. I removed this film and the screen contrast increased slightly. The film is almost invisible, but it was on my watch.
UPD
.
Over the past four days, since the quartz was replaced, the clock has moved forward by two seconds. 15 seconds per month.
For a cheap watch and free quartz, I think the result is satisfactory. Personally, it completely satisfies me)))
You can, of course, look for quartz watches for pennies at flea markets, pick up a bunch of quartz from there and experiment with precision... but we’ll leave that to perfectionists and die-hard freaks)))
The comments provide a recipe for finer-tuning the accuracy by soldering miniature ceramic capacitors. As an alternative to replacing quartz, it is quite viable and sensible. The main thing is that there is a place where to place these capacitors. Well, the presence of them...
And in general, friends, the main thing is not the review, the main thing is the comments)))
Thank you all for valuable ideas and various discussions)))
Why do wristwatches start to lag?
A watch is an invariable accessory for business people, with the help of which they find out the current time. Watch manufactories around the world never cease to improve watch mechanisms, which is why they constantly change their designs and get more and more high accuracy progress. However, over time, clock mechanisms malfunction or simply start showing the wrong time for some unknown reason. But if you immediately buy a high-quality Rado watch, then such troubles are unlikely to ever happen to you.
All modern mechanical watches, like hundreds of years ago, consist of many transmission mechanisms, distributors and movement regulators. Their smooth operation is a prerequisite for accurate time display. Most of all, the accuracy of a mechanical watch depends on the mechanism regulator. The main task of this device is to measure certain time...

The accuracy of quartz watches is plus or minus 30 seconds per month, that is, 1 second per day. But as a rule, even not very expensive watch models run second per second. In my 20 years of working in the watch business, I have seen very few quartz watches in a hurry. Basically these were our domestic watches with low-quality quartz. Quartz watches can lag for three reasons:
1) the battery is dead (usually this is the main reason)
2) the lubricant in the mechanism has thickened (if the watch has been used for a long time without maintenance)
3) dust or other got in foreign body into the watch mechanism (this happens in watches with poor case sealing, usually in very cheap Chinese watches).
Some watches, for example from Seiko, provide information about a low battery - the second hand on the watch starts moving after 2 seconds, then if the happy owner of such a watch does not pay attention to this, the second hand starts moving after 5 seconds...

Every clock has some device that measures equal periods of time. For example, in the oldest wall clocks it is a mechanical pendulum. I don’t know how it is on simple walking watches, but on fairly solid watches there is a correction device at the end of the pendulum, roughly speaking - a small screw on which a nut is screwed. By moving the nut in one direction or the other, you can adjust the duration of one oscillation, and thereby the accuracy of the watch. In mechanical watches, this device is called a “balancer”. This is a “wheel” with a spiral spring that rotates approximately half a turn in one direction or the other alternately. One end of the spring is rigidly attached to the balancer, and the other passes through a kind of “fork” that can move. By moving this fork, the length of the free part of the spring is adjusted, and thereby the accuracy of the move.
In electronic devices (just watches, phones, TVs, recording devices, microwave ovens, washing machines, you never know...

In general, I began to reason in the Holmesian way - deductively, what could
be the reason for such a lag? Ideas with goblins and hobbits living
in the clock, threw it back immediately. Although, I must admit, after a glass of white wine,
the ideas didn't seem so absurd.

The noise of the interior clock mechanism is not regulated by any GOST - so it is difficult to appeal to the quality of repairs.
The larger the gap in the clock gears, the more “noisy” they are, but even this noise is difficult to distinguish from the usual city background. So, the older they are, the noisier they tend to be.
Today there is only one wall clock mechanism system that eliminates noise altogether - Sweep Hand - a “smooth hand”, there is not 1 pulse per second on the rotor of the mechanism, but usually 5 pulses per second. Therefore, the movement of the watch is almost completely silent.
As far as I remember this watch (your brand) at all. There is an ordinary mechanism there (it seems to be Taiwanese, these are usually good mechanisms), there is no point in replacing it with another one of the same type (in fact, there is a lot of fuss, it is easier to repair yours, especially since repairs there are very easy to carry out).
But it’s quite easy to check whether the master has replaced the mechanism in your watch - just compare...

A clock is an invariable means by which the current time has been determined at all times. But watch companies around the world work tirelessly to improve watch mechanisms, which leads to changes in their appearance and increasing the accuracy of their movement. However, over time, the clock mechanism may malfunction, or simply, for some unknown reason, begin to show the wrong time.
If you immediately buy high-quality copies of Patek Philippe, then such a problem can be avoided.
All components of a mechanical watch are a kind of engine, consisting of transmission mechanisms, a movement regulator and a distributor that transmits impulses to the regulator. The accuracy of a mechanical watch is determined by the clock mechanism regulator. It is this device that measures certain periods of time. If the clock in this device is broken, then the clock may well begin to lag.

The work of a clock is usually called “running”, so during operation it can be either late or in a hurry. Each type of watch will have its own reasons for rushing.
Posting Sponsor P&G Articles on the topic “Why watches are fast” Why watches are slow How to transfer an employee to part-time work How to convert kilowatt hours to kilowatts A mechanical watch can be fast because a hair of the balance has become magnetized. Take the watch to a workshop, they will demagnetize it. “Hurry” can also begin because oil got on a hair’s breadth, for example, if you tried to lubricate the mechanism yourself.
Electronic watches may be in a hurry due to a pulse generator that can no longer withstand the number of pulses per unit time. To ensure that your digital watch lasts a long time, take care of it, try to periodically wipe off dust and do not let the clock mechanism get wet. Consider temperature conditions, some models stop working due to sharp cutting. Treat your watch carefully, as the accuracy...

By the way, if the battery dies, you will not start the computer. and, in addition, you risk crashing the system.
There's no need to scare me. This only happened in the days of Pentiums and with one type of motherboard, where the battery was non-replaceable and was filed together with the BIOS (also seemingly non-replaceable). A dead battery called Beavis' karachun. But it was a scheme similar to direct sabotage. In the normal case, a dead battery, in the worst case, completely resets the BIOS to default settings: it forgets the date and time and requires them to be set at boot (via F1, usually). There may also be a variant of partial “amnesia”, when the time that has passed during a power outage is forgotten. But usually, if you don’t disconnect the computer from the network at all, just turn it off, then it can work with a dead battery indefinitely.
By the way, the fact that the service life of a computer with a dead battery is 5 years is not a fact. The store might have put in some kind of defective battery. Sometimes they die within a couple of years.

07/09/2009, 14:40 Stfw.Ru: The first IBM PC could not remember the time when you turned it off; you had to re-enter the date and time; when you turn on the computer. Some companies have entered the market with products that solve this problem. IBM got around this problem by installing a small battery in the IBM AT, which allowed the built-in clock to run before the computer was turned on again. Now such a battery is an almost universal component for computer systems; it also supplies power to the CMOS memory, which stores the BIOS (Basic Input/Output System) configuration settings.
If the battery runs out, the watch will run slower than it should and lag. This is the most common reason for a computer's system clock to lag. There are others possible reasons, such as software problems. Diagnose whether the problem is caused by the equipment or software- simple: if the clock is slow, when...

Each tablet has the ability to display the date and time corresponding to the selected time zone. Late Android versions(4.1+) determine such parameters automatically. However, it happens that the initial setting does not coincide with the real indicator, and then an adjustment needs to be made. Often when the clock is changed to winter time or summer time a system failure occurs, and the device then begins to provide incorrect information.
It must be said that similar incidents also happen when the tablet is turned off at night in order to save battery. Note that in solving the problem discussed here, changing the firmware to latest version, which automatically adjusts the named indicators.
So, let's consider the following option: the cellular operator provides false data, because the SIM card for the device was purchased in another region, where different settings apply. You can always check this fact in the “Date and Time” section, and distorted indicators should be...

Hi all!
This strange thing happens to our clock that hangs in the kitchen. Recently I noticed that they began to lag behind the correct time, well, of course, the battery began to run out. By the way, until I noticed that the clock was slow, I was late everywhere all the time, because... I was guided by this clock...
And so, I bought new batteries, changed them and... everything seemed fine, but after a while I began to feel that time was passing quickly)) Yesterday I looked at the clock, that it was time to put the child to bed nap, went to bed, left the bedroom - looked at the other clock and was stunned! How did it happen that I put the baby to bed in 5 minutes, although I had been lying on the couch with her for about 40 minutes. I went to check the clock and saw that it was already 45 minutes too fast!!! How? The battery is new, this has never happened before - has the watch gone crazy??? I specifically photographed the clocks in the kitchen and in the living room (the difference in the photographing process is...

It’s very strange, the Swatch watch, which was not bad, worked for 2 years (and this company doesn’t even give a guarantee because of the confidence in its “eternal” quality), recently began to lag. Replaced the battery. After some time - again. in the workshop they said that it is useless to repair, it is disposable, otherwise everything is in order with the mechanism. I got tired of it and decided to throw it away. But, to begin with, I just put it in the desk drawer at work before leaving, in the morning - perfect, they didn’t lag behind for a minute. I put it on my hand and immediately there was a lag. So this is what I mean - I know that this may be related to my energy and not very good. Can anyone clarify?
It depends on the magnetic field(your personal biofield)!!! By the way, if they fall behind, it's not very good. It says that your internal clock. Please note - you often either sleep until lunch and go to bed late, or vice versa!!! In short, the mode that suits you...

Quite often people ask whether it is possible to move the arrows back. The time on the dial can be set by turning the hands both forward and backward. It is better to rotate the arrows in the direction where the number of revolutions is lower.
An exception to point 1 are watches with a date and other complex functions. It must be remembered that in such a watch the hands should not be turned backwards while the calendar mechanism is engaged or the calendar may be engaged during installation. Watches come in a variety of designs, so it is a good idea to consult with a representative of the watch manufacturer for each model. If you are tormented by doubts, move the arrows only forward, calendar and complex functions set only after setting the exact time.
When setting the time, turn the arrows forward not in one continuous movement for several turns, but intermittently, in small portions. This will save the minute trib1 from breakage, especially if it is tight...

The main parts of a mechanical watch are the motor, the transmission mechanism, the movement regulator and the distributor that transmits impulses to the regulator. The clock mechanism regulator is responsible for the movement of mechanical watches. It measures certain periods of time per day, for example, a second, half a second, a quarter of a second. If this device begins to adjust to a different value, for example, indicates a lower number, then the clock will begin to lag.
The accuracy of the watch can be checked using a special device called a thermometer, but for this you will have to open the watch, and therefore it is better to take it for repair. Note that if the clock moves slowly, it means that the main elements of the thermometer are located too close.
Quartz watches work thanks to quartz crystals. The main components of such a watch are a battery, an electronic generator, a counter divider and a special amplifier that drives the clock mechanism. Quartz watches may lag due to an element...

It has long been no secret that mechanical watches are the most "capricious" than quartz. Battery-powered watches are less susceptible mechanical damage from impacts, and the recommended period for carrying out is once every 4-5 years.
But, nevertheless, quartz watches also have a number of their own “diseases”.
Dead battery
The most common reason for a quartz watch stopping is a dead battery. Often, a warning that the battery has exhausted its resources is the second hand, which begins to jump through several divisions. This function is called EOL (End Of Life).
EOL is special system, notifying the owner of a quartz watch that the battery needs to be replaced. In watches equipped with this system, about 2 weeks before the battery is completely depleted, the second hand begins to behave in a special way: it stops moving clearly every second, but waits 4 seconds and jumps forward immediately by 4 (sometimes 2) divisions. Thus, the watch makes it clear that it is time to change the battery.
Sometimes the clock just starts to lag, but more often, it just stops.
In any case, it is better not to delay replacing the battery and have it replaced at an authorized service center with a guarantee for the battery and tightness.
Quartz movement board
The next disease of quartz watches is considered to be the power consumption of the quartz movement board. It happens that the board fails and begins to consume too much energy, thereby quickly destroying the battery. Several factors can lead to this failure:
- moisture got inside the watch case and corrosion formed on the board;
- the Chinese battery leaked;
- The battery has been left in the watch for too long.
In rare cases, with such a breakdown, it helps complete prevention watches, but often you have to change the entire mechanism completely.
Woe-master
Quite a lot of watch owners believe that they can cope with replacing the battery on their own, or they rush to a technician close to home, without thinking about the consequences, the availability of knowledge and tools. As a rule, when purchasing Swiss watches, consultants recommend servicing service centers, and they recommend it for good reason. But, based on statistics, in authorized workshops the flow of watches with broken seals, torn coils and leaking batteries does not dry out.
Stopping the clock
Another reason for a quartz watch stopping, in addition to a dead battery, may be the need for preventive maintenance. The fact is that quartz Swiss Watches consist not only of an electronic quartz unit, but also of a mechanical analogue one with a wheel system, in which, over time, parts also wear out and dust and dirt get inside.
Shock resistance of watches
Despite the fact that quartz watches can withstand small shocks well, it is not worth testing their durability. In fact, according to GOST they must withstand a drop of one meter onto a hard wooden floor. And, nevertheless, there are quite a lot of calls to the service center with damage from impacts. The result of a fall or blow is:
- displaced or broken hands on the dial;
- cracked quartz;
- broken teeth;
- broken glass, etc.
All this naturally leads to the clock stopping or the mechanism breaking down.
Take care of your watch!

Maya Taturevic September 30, 2018, 11:11 pmA watch is an excellent accessory that has not lost its relevance even in the century computer technology. With their help, we arrive on time for business meetings, are not late for work, have time to take our children to kindergarten and we always know how many minutes are left until the long-awaited meeting with your loved one. Simple wall-mounted or antique floor-mounted, mechanical or quartz - such time meters can be found in every home. But even the most precise mechanism goes astray from time to time, and then the clock begins to deceive us: sometimes they will show more time, sometimes less. The result is missed meetings and being late for work. Let's find out why the clock is fast and how to fix this situation.
About the accuracy of the clock
Many people think that the term "clock accuracy" refers to how accurate the time is. Watchmakers believe that precision is the inevitable deviation of the watch from the exact time. As a rule, such measurements are made once a day. There is even a special table of permissible deviations for different types hours:
- mechanical watches can be fast or late by 30-60 seconds;
- quartz - for 20 seconds;
- watch with chronometer no more than 5 seconds.
Of course, even the most accurate watch Sometimes fail - in most cases it is enough to tighten them up to the exact time. If the watch constantly deceives you by showing the wrong time, then it’s time to contact a watchmaker and eliminate the cause of the breakdown.
The clock is rushing
The clock has started to rush, what should I do?
It's worth starting with the fact that all mechanical watches have a small spiral. The degree of tension and frequency of oscillations in it are constantly changing - the lower the frequency of oscillations, the greater the inaccuracy of movement. Don’t think that this is typical only for Soviet models - modern mechanical watches can deceive you by 1.5-2 minutes.
Let's look at what other reasons for inaccuracy there may be:
- Reaction to temperature changes (heat, humidity, severe frost).
- The degree of cocking and unwinding of the spring.
- Thickened grease.
- Hand position. If she's down all the time, then the time on the clock will be a couple of minutes longer than it actually is.
- Reaction to changes in the Earth's gravitational field.
There is one very important rule: the smaller the spring winding, the faster the clock goes!
If your wrist time keepers start to rush, do not try to fix the problem yourself. This requires a trained eye and precise knowledge of the reasons. An experienced watchmaker will fix the problem in just a couple of hours, but you risk completely ruining them.

Is the clock running fast - an anomaly, a warning or a simple malfunction?
Our ancestors believed that the health of a watch is directly related to the life of its owners. So, if you are unhappy with yourself and the events happening to you, then the clock will go wrong. Only one thing can correct the situation: put things in order in your thoughts and soul, then time will make friends with you.
The more fuss and worries, the more problems you try to solve at the same time, the more your watch will lag
These little time keepers are sensitive to your experiences: as soon as you become depressed or think that everything is bad in your life, the clock begins to get upset. There is a proverb: “Happy people don’t watch the clock.” It has a double meaning, one of which is that when everything in your life is sorted, the clock works properly.
If your walkers are constantly late, it means that you are fixated on the past, and you need to start urgently life with clean slate . The clock is a kind of prompter that signals: change urgently and change everything around you!

Mechanics: setting the speed of a mechanical watch
This version of the clock can be found in every home - many models have survived from Soviet times. Such specimens will serve you for many years, but they may not show exact time. For example, the Vostok watch continually tends to run ahead - this can only be corrected by specialists.
Vostok Clock
A watch is a very delicate mechanism that requires care and careful handling. It's worth it protect from temperature changes, extreme situations and high humidity, but there are several other reasons why they start to fail:
- Small building. The small balancer and winding spring slow down the energy of the spring, hence the lag of the watch.
- Friction dominates the balance energy. This results in rapid wear of spare parts and slow speed.
There can be only one answer to the question of what to do if your mechanical watch is in a hurry - contact a repair shop. The watchmaker will clean and adjust the length of the balancer, replace faulty parts, and lubricate the watch parts with oil. After such repairs, your walkers will serve you for many years.
Mechanical watch is in a hurry
Why do digital watches start to rush or lag over time?
These walkers are based on a clock generator: it is a small microcircuit that emits a pulse once every time. Many watchmakers have tried to solve the problem of a malfunction in them, but if an electronic watch is in a hurry, it is almost impossible to fix something inside this mechanism. In any case, they will slowly lag behind or rush.
This is caused by two things:
- The impossibility of creating a perfectly accurate microcircuit - there will certainly be an error, albeit in a split second.
- Changing internal parameters - reducing the capacitance of the capacitor, the response time of the transistor gate.
In this case, there is no point in taking the watch to the workshop - electronic options are inexpensive, and it is easier to spend money on buying a new watch.
The electronic clock is in a hurry
Wall clock mechanism and wall clock accuracy testing
If you are the owner simple option on batteries, it is easy to fix the breakdown - just replace the battery with a new one, and they will again show the exact time.
It is much more problematic if a self-winding wall clock is in a hurry - in this case, you can try to fix it yourself. The mechanism of such a watch is very simple, and it can work without interruption for about three years.
After three years from the date of purchase, carefully clean the watch from dust and dirt, and then lubricate it with a thin layer of oil.
Failure in the accuracy of the stroke can also occur due to the fault of special hammers that strike the strike springs. While the springs are wound, the accessory shows the exact time. However, this is very easy to fix: just turn the minute hand in the direction of its movement, and the clocks work properly again.
Don’t want to waste time on DIY repairs or are you simply afraid of damaging such a fragile mechanism? Take it watch to a repair shop– there they will quickly return to perfect accuracy.
Self-winding wall clock in a hurry
Quartz watch
These watch models are much more accurate and reliable than their mechanical counterparts. However, they can also run ahead or lag behind. Watchmakers identify several reasons why quartz watches are in a hurry:
- Battery energy consumption. A standard one can last about a year - as soon as it starts to shrink, the walkers speed up their pace. Avoid this situation a clock with a generator will help(frequency must be at least 144 Hz): with careful use, they will serve you for more than 10 years.
- Wear and tear of the quartz crystal (the older it is, the more changes occur in the resonant frequency).
- Changes in temperature conditions.
- Use in conditions of high humidity.
- Water getting inside.
If you have a question: “why is an electronic watch in a hurry” and there is a need to repair this useful wrist accessory, then do not even try to fix the breakdown yourself. Only a professional can help here! If cheap walkers are acting up, buy new ones, because often repairs will cost you the same amount as buying new ones. It makes sense to take an expensive quartz watch to a workshop - a good master will give it a second life.
We all prefer different watches. Some wear only mechanical models. Others decorate their homes with a massive wall cuckoo clock or complete the decor with a simple clock with colorful patterns. To live for a third and a day can't live without theirs quartz clocks. Regardless of the type, all watches require careful care and timely repairs. Repairing it yourself can lead to disastrous results, which is why you should entrust the repair to professional watchmakers.

And it’s even easier to buy new ones - these days there are many models in stores, among which you will certainly find your ideal watch.
If quartz is so wonderful, you may be wondering why quartz watches don't keep time with real-time accuracy forever. Why does it still lose seconds here and there? The answer is that quartz vibrates at a slightly different frequency and at different temperatures
and pressures, so that his timing abilities are affected by a tiny misfortune in the warmth and, in the cooling, changing around us. In theory, if you keep the watch on your wrist all the time (which is at a more or less constant temperature), it will keep better time than if you keep them in a different place (resulting in a different temperature each time). But even if a quartz crystal can vibrate at a constant frequency, on a microcircuit, tiny imperfections of the earth, friction, and therefore can introduce errors in the timing of minutes. All these effects should introduce inaccuracy until the second day in the clock. Typical quartz and watches (keep in mind that a second loss may occur one day and be compensated for the second and the following day, so total accuracy may be as good as a few seconds per month).
It is important to remember that piezo quartz: will vibrate when you apply electricity to it, or it will output electricity when you force it to vibrate. A crystal oscillator uses piezoelectricity in two ways: at the same time!
I have a circuit made up similar to it, like a quartz crystal separate from the microchip circuit, but, in fact, it is a private part of the printed crystal and two electrodes wired into it. You can clearly see them in the photo of the inside and should look and photograph the generator itself: they both have silver legs sticking out of the cylindrical metal. Basically, it is a crystal oscillator, but another component of the chip is wired into the circuit, like a resistor or capacitor.
I say "circuit", but that's just thinking about the oscillator within two separate circuits, like on the same microchip. The first circuit (we call it the input) stimulates the quartz crystal with electrical flashes. Feeding electricity into quartz makes it vibrate (or, if you prefer, oscillate or resonate) through what is sometimes called the inverse piezoelectric effect (where electricity produces vibrations). The oscillator is configured so that the quartz directly vibrates 32,768 times per second. But remember, the piezoelectric effect is now normal: when a piece of quartz vibrates, it generates an electrical voltage. The second microchip circuit senses the "output voltage" (supposedly 32,768 times per second) and divides the frequency of receiving pulses once per second to control the engine shifting into gears. I'm watching with a digital display, instead of transmitting, the chip repeatedly divides the oscillator frequency to drive the hours, minutes, seconds (as shown in the picture).
The quartz oscillator divides the binary, counters and displays of a typical Timex digital watch with US Patents 3,863,436.
Operation: How a digital crystal oscillator controls the hour and minute of the time display and a flashing colon between them (“0:32″) to indicate the seconds. The oscillator (yellow) vibrates 32,768 times per second. Binary divider (blue, left), by 15 times, TO CREATE 1 Hz (one per second) pulse that drives and flashes. The 1-Hz signal from the divider itself is about 60 minutes and another 12 hours. Serves the signs of the driver set (red), which is the power of the parts in the digital display.
When the crystal vibrates, it produces a piezoelectric voltage. This was detected using a second set of electrodes (attached to another part of the same crystal) and fed into the output circuit. When quartz technology is miniaturized for use in compact wristwatch, it became clear that smaller generators were needed and there was no room for two pairs of electrodes. This is why modern generators use one pair of electrodes to stimulate both crystals with energy and detect their vibrations.
That's as much as I'm going to tell you. If you want to learn more, you might want to take a look at the following sources. Warned that they are complex and difficult to understand, if you have some knowledge of electronics then go ahead.
In one of early species quartz oscillator, the quartz crystals had two sets of electrodes located on it. The first set was connected to the input circuit electricity and fed into the crystal to make vibration. When the crystal is shaken, a piezoelectric voltage occurs. This was marked with a second set of electrodes (stuck with some of the same crystal) and fed into the output circuit. When used in miniature quartz technology in compact wristwatches, there is an obvious need for small and oscillators. In one early form of quartz oscillator, the quartz crystal had two sets of electrodes mounted on it.
