How can I tell if my Cartier watch is accurate?

1) If the watch is aligned with the time every few days, and the time signal of the radio station is basically the same, this is an accurate watch.

2) The watch starts to be consistent with the radio station time signal, but there is an error every day after operation. The cumulative increase is the same, but the error value is the same for each day. If the error does not exceed the quality standard of the watch, it is also a qualified watch.

If the error value exceeds the specified standard, you can toggle the fast and slow hand to adjust it to make the time more accurate.

3) If the watch is matched with the radio station time signal, sometimes it is slow, sometimes it is fast, there is no certain regularity, but the error is very small, it may be related to the use of the state, and it is also a qualified watch. If it is found that the error is too large, there is no regularity, and it cannot be adjusted by moving the fast and slow needle, and its accuracy cannot be guaranteed, it is necessary to make it meet the specified standards through maintenance and proofreading.

1. When repairing an Apache brand watch, all the watch parts should be disassembled, the movement should be wiped with gasoline, and then other equipment in the watch should be cleaned by professional equipment, and finally oiled and assembled. In addition to the parts inside the watch, the watch shell should also be polished when the watch is cleaned. Because Apache watches have very high technical requirements, cleaning the watch is a very delicate task, and professional cleaning usually takes 5 days to complete.

Second, in the maintenance of Apache watches, the process of oil lighting seems easy, but in fact, there are many places to pay attention to, first of all, you must confirm whether each part, plate, and gemstone is clean? Any remaining dirt must be removed in a reliable manner, otherwise the effect of the oil will be greatly reduced. 3. In addition, the oil used in Apache watch parts must be special oil, and the oil on each part is different, such as the power system must use slightly viscous oil (8300 oil), the gear system must use thinner oil (8000 oil), and the escapement system must use special oil (9010 2 oil), do not use an oil to the end, otherwise it will cause serious damage to the Apache watch movement.

All kinds of oil pens are also indispensable tools when lighting oil, usually a group of 4, green 8200, blue 9010 2, red 8000, yellow 8300, note that each oil has its own special oil pen, can not be mixed with other when using, otherwise the oil will deteriorate and deteriorate.

Cartier watches have always been a status symbol, and many people who own Cartier watches can't put it down. Even Cartier watches need to be cared for and cared for. In the daily use of Cartier watches, a slight carelessness may cause Cartier watches to suffer heavy pain, so we need to take more care of them and protect them.

What is the reason for the inaccuracy of Cartier mechanical watches?

1. Fast and slow needle: fast and slow needle is an economic structure that is convenient for time calibration, but theory and practice have confirmed that it will affect the isochronism of the system, and may also produce a potential difference, and these timing errors are relatively random and cannot be compensated or offset. The workarounds are:

Minimize the distance between the inside and outside fast and slow needles; But the best way is to adjust the speed by adjusting the inertia of the balance wheel, the friction between the wheel, the automatic watch spring and the barrel, the screw self-locking, etc.; On the other hand, friction can lead to a decrease in transmission efficiency and wear of parts, which can affect timing. Commonly used solutions: improve lubrication conditions, according to different requirements, choose different lubricating oils; Jewel bearings or gaskets; Improving the tooth surface condition of gears, including the use of scientific conjugate tooth shape and improving surface finish, etc., but generally the tooth surface is not lubricated (in this case, the resistance caused by the viscosity of the lubricating oil may be higher than the friction).

The easiest way is to use a small compass that is more sensitive, flat on the table, when the compass hand is stationary, the watch repeatedly and quickly skim over the compass at close range, change a few more directions, repeat the above actions, as long as the compass hand moves, it indicates that the watch has been magnetized.

There are two situations in which the watch is not allowed.

If it's just a little fast, for example, it's only more than ten or twenty seconds a day, then the gossamer circle is a little shorter, and this situation is okay.

If you know a little bit about the watch, you can adjust it yourself, if you don't understand, you have to find a watch repairer.

Mechanical failures such as magnetism, lack of maintenance, malfunction of the watch hairspring, escapement system, slippage of parts, etc., can cause the watch to be fast and slow. Mechanical watches are sometimes fast and sometimes slow, and it may be caused by severe impacts, water ingress, etc.

How many errors will there be when the watch goes, specifically depending on which type of watch is quartz, mechanical, and electronic, as you said, it is not allowed to buy a new one, it should be a fake Disney product. And judge that your watch should be below 100, it should be that the watch movement is very inferior or refurbished, such a watch can not be repaired, you should be a jewelry to use, repair is not meaningful!

1. See if the crown is pulled out, the crown is pulled out, and the watch stops.

2. Whether the second hand touches the glass, there will be a circle mark on the glass.

3. Whether the three watch hands are not well balanced, causing contact and causing stopping.

4. Whether the battery is exhausted or not, it generally needs to be replaced in 1-2 years.

If the problem is still not solved by visual inspection and battery replacement, you should go to a professional watch maintenance department for inspection and repair.

The demagnetization of a Cartier watch is theoretically to place the Cartier watch in a strong alternating magnetic field, and the intensity is gradually decayed. Usually a large hollow coil is used, which is applied to alternating current, and the Cartier watch is placed in the hollow coil and then slowly withdrawn, which is equivalent to gradually reducing the strength of the magnetic field. This action has to be repeated many times, each time changing the orientation of the Cartier watch by 90 degrees, because the demagnetization effect is best when the magnetic field lines of the demagnetized magnetic field and the magnetic field lines of the demagnetized watch are in the same direction, and when they are at an angle of 90 degrees, they are invalid.

Therefore, it is necessary to demagnetize the Cartier watch in all directions in order to remove it cleanly.

Reasons why the watch is not running accurately:

1. Insufficient power reserve. If the amount of exercise is small, it may also cause a lack of power reserve, so you can replenish the power by winding it manually, and then observe whether it continues to be fast or slow.

2. The watch has been hit or impacted, which may cause loose damage to the internal parts and may also cause the problem of running time.

3. The lack of oil in the movement or the wear and aging of the internal parts may cause the problem of running time, which needs to be maintained.

4. The watch is magnetized: If the hairspring of the watch is magnetized, the watch will not be accurate. The influence of the wearer's usage habits may cause an increase in the time error. Sending the watch to a repair center for inspection and adjustment will restore the watch to its normal tolerance.

Hello! After-sales center in: Room 1003, 10th Floor, Hongyi International Plaza, No. 299 Nanjing East Road, Huangpu District, Shanghai, when your watch fails, you should go to the regular after-sales center, and the watch will be comprehensively repaired and inspected by professional technicians.

1.Insufficient power reserve: You need to check whether the power is sufficient, if the amount of movement of the self-winding mechanical watch may also cause insufficient power reserve, you can replenish the power by manual winding, and then observe whether it continues to be fast or slow.

2.Insufficient battery: If the quartz watch suddenly finds that it is slowing, it is likely that the battery is insufficient, and you can send the watch to a special repair point to check the battery level.

3.Having been hit or impacted: The watch is very tight, and if it is hit or hit, it may cause loose damage to the internal parts, or it may cause time problems. This is to be dealt with in a timely manner.

4.Need for maintenance: Lack of oil or wear and tear of internal parts of the movement may cause time problems, which need to be serviced and sent to a designated repair shop for maintenance services.

5.In addition to the above common situations, the watch is affected by some ambient temperatures: if the balance spring of the watch is magnetized, the watch will not be accurate.

1. Magnetic field. The magnetic field has the greatest impact on the hairspring, the strength can change its elasticity, and it will also deform the hairspring under the action of the magnetic field.

2. The influence of temperature.

The influence of temperature is mainly reflected in two aspects: the change of temperature will affect the hardness of the hairspring, and at the same time change the direction of the balance wheel, which can directly affect the inaccuracy of the Cartier mechanical watch; In addition, changes in temperature can affect the viscosity of the lubricating oil, which in turn affects the efficiency of the tourbillon transmission and the timekeeping of Cartier's mechanical watches.

3. an escapement.

The influence of the escapement is mainly on the balance spring system during energy transfer. The balance spring system maintains a fixed oscillation frequency only if it vibrates freely. Obviously, the process of energy transfer of the escapement affects the oscillation frequency.

The theory suggests that this effect decreases when the transfer process approaches the equilibrium of the equilibrium.

4. Environmental impact.

Cartier's mechanical inaccuracy comes from the influence of the external environment. Commonly used protective measures are: shockproof design, waterproof design, anti-magnetic design, additional protective shell, etc.

5. Friction.

Friction usually has two sides. On the one hand, the friction between the watch friction wheels, automatic springs and the barrel makes the screws self-locking; On the other hand, friction can lead to reduced wear and tear of transmission efficiency and parts, affecting the time of Cartier watches.

Common solutions: improve lubrication conditions, choose different lubricating oils according to different requirements; use of jewel bearings or washers; Improve the condition of the gear tooth surface, including scientifically conjugated tooth shape and improve surface finish.

Cartier Code Query Official**:.

The code of the Cartier watch is queried on the back cover of the watch, which has a 4-digit technical designation of Cartier, and a 6-digit letter plus a number is an independent number. There is also an independent number on the certificate of the form, which is filled in after the later salesperson. Cartier watches on the back cover is material, waterproof and deep, some also have the name of the series, as well as the only number, Sun blind fiber and movement model, if there is no model check, it is imitated the inquiry number, if you need to know the model number, you can find it on the sales list, the watch usually starts with W.

If there is no bill of sale, you need to show ** (front, back, side, strap) to identify. The Cartier Manufacture has its own fixed numbering rules and has serial numbers for each of its watches. According to this number, you can find out the specifications and models of the watch, even the date of manufacture and the place of sale, while the fake Cartier watch only uses a number, or even no number, which is easy to distinguish.

Analysis of the reasons why the watch goes fast.

1. The speed of a mechanical watch is mainly determined by the pendulum frequency, usually the larger the pendulum amplitude, the smaller the pendulum frequency, and the smaller the pendulum amplitude, the greater the pendulum frequency. Generally, watches rely on the retraction and release of the hairspring to control the swing, which is the basic principle of adjusting the speed and slowness. If the hairspring is longer, the swing will increase, the frequency will be smaller, and the watch will be slower; Conversely, the more the pendulum frequency increases, the faster the watch will be.

2. The structural problem itself, due to the gravitational force of the earth, the offset of the horizontal position and the vertical position will produce a displacement, the mainspring is tightened from the top to the relaxation, the torque is unbalanced, and the external temperature, magnetic field, vibration, etc., even if the mechanical watch increases some frequency, it is impossible to achieve the accuracy of the quartz electronic watch.

3. The effect of the magnetic field, after the hairspring is magnetized, the circle between the rings is only shown when wearing, there is a sticky or short-term lap, especially in the façade, the hairspring will hang down due to its own gravity, and the shaking of the arm will intensify its radial movement, and the magnetic energy utility is shown because of this.

4. The balance of the balance wheel and the balance spring, especially the balance wheel, the balance wheel is very poor, which will cause the balance wheel to highlight the precision change of the surface under a certain swing.

Analysis of the reasons why the watch slows down:

1. The amount of activity is not enough, and the kinetic energy is insufficient. Automatic watches need to be worn normally for about 8 hours a day, and need normal and appropriate amount of exercise kinetic energy to support time, and wearing 8 hours a day can support about 36 hours of time.

2. The watch is magnetized. Generally, the watch is close to the magnetic field, such as placing it next to electrical appliances (such as stereos, refrigerators, computers, etc.) that generate magnetic fields, and magnetic objects (such as magnets, mobile phones) will cause magnetism, which will affect the watch to run fast or inaccurately or temporarily stop.

3. The oil sludge of the movement is dry. If the oil in the watch movement is dry, it will increase the frictional resistance between the parts in the watch, causing the watch parts to be damaged and unable to operate normally.

Hello, glad to answer for you!

Reasons for inaccurate time: insufficient kinetic energy reserve of the watch, insufficient battery of the watch, the watch has been hit or hit by an external source, the watch has not been maintained for a long time, and the watch is affected by magnetic fields.

Cartier watches have mechanical watches and quartz watches, the reasons for the inaccuracy of mechanical watches and quartz watches are different, mainly depending on your watch mechanical watch or quartz watch, you can take the watch to the after-sales center for technician testing.
