What is a Zenith watch with a power reserve of 50 hours

It is a mechanical watch from Zenith that can run for 50 hours when fully wound, compared to 36 hours for a normal mechanical watch, and it is also less accurate. Mine has been using this for more than 10 years and can walk for 48 hours straight.

That is, the movement of the self-winding mechanical movement is based on the movement of the wearer's wrist. After the full wind, the power reserve time of the watch is 50 hours, which means that even if you do not exercise after the full wind, you can have 50 hours of power to use, that is, you can not move at all when you sleep at night.

Watches with a power reserve indicator usually have a display window on the dial, also known as an energy window, which shows how long it can run before winding for mechanical watches, and how high or low the battery level is for quartz watches. Clocks powered by mechanical devices may not go correctly or even stop if they are not wound in time. The earliest power reserve was found centuries ago, when ships at sea relied on accurate sailing clocks to measure longitude and ensure safety.

A fully automatic watch is wound entirely by the swing of the arm.

Therefore, if the watch is left for too long or the amount of arm activity does not meet the requirements of the watch winding every day, the watch will cause the mainspring to be winding and the potential energy is insufficient, which will cause the watch to be unstable or stop when it is not worn at night.

If this happens, we can manually do an arc movement before the watch is placed. Or use the manual winding function to wind the watch. This keeps the watch with enough kinetic energy storage to keep it running until the next day.

Five common reasons for watch time error and watch time inaccuracy:

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

2) Insufficient power: If the quartz watch suddenly finds that it is slow, it is likely to be caused by insufficient battery energy, and you can send the watch to a special maintenance point to check the power.

3) Hit or hit: The watch is very tight, if it is hit or hit, it may cause loose damage to the internal parts, and it may also cause the problem of running time. This is to be dealt with in a timely manner.

4) Need to maintain: The lack of oil in the movement or the wear and aging of internal parts may cause time problems, which need to be maintained, and need to be sent to the designated maintenance point for maintenance services.

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

Usually the watch industry recommends that the watch must be sent back to the service center for maintenance every one to three years, depending on the situation

First, the watch that is worn every day, it can also be said that the watch does not leave the hand for 365 days, if you find that the error of the watch is very large, or the watch is water, it is best to send it for repair and maintenance; If everything is fine with your watch, it's best to have it serviced every three to five years; Some people do not leave the watch, a wear is more than 10 years, this is not the way to wait for the watch, because of long-term use, the lubricating oil of the watch will still be lost or dried up, in the case of oil loss, it will accelerate the wear of the shaft; There are quartz particles in the air that we can't see with the naked eye, which will adhere to the oil, and if you don't maintain it for a long time, and let the watch keep going, it will only accelerate the wear of the shaft; Some people wear it for 10 years, 20 years, the watch will go, never want to maintain, and when it fails, many parts have been seriously worn, after maintenance, its accuracy will be greatly reduced, not as good as the new watch.

There are three reasons for inaccurate time:

First, the power is insufficient.

The power required by the watch is not the same, like a mechanical watch, it relies on the shaking of daily wear to store power, if you don't wear it for a long time, there is no power, then the watch will definitely stop or slow down. The manual one needs to be wounded up and down from time to time, and some rely on electronics to maintain rotation, so if the watch is inaccurate recently, it is likely that the electronics are out of power and need to be replaced.

2. External interference.

This is whether you pay attention to it when you wear it daily, for example, watches are relatively squeamish, waterproof, anti-magnetic, and shock-proof, if you don't do a good job, it is normal for the watch to be inaccurate. If you wear a watch that cannot be worn for strenuous exercise, and you wear it to play golf or badminton, the strong vibration may cause damage to the parts inside the watch, and the watch will not be accurate.

In addition, it is a cliché that watches are afraid of magnetism, if your job is to engage in some research things and need to be in frequent contact with large electronic devices, then try not to wear a watch, because the magnetic field existing around it will disturb the normal walking of the watch. Some people say that the watch is bought to wear, and the baby is not good every day, so why buy it? That's true, but you should also be careful when wearing it.

3. Proper maintenance.

The watch is more precise, there are more small parts, and the mutual fit between the parts can operate normally, so the haul is indispensable for friction, so the watch is oiled, and it will inevitably dry up after a long time, plus there may be some impurities into the watch, so it will cause the watch to go inaccurate, at this time you have to go to maintain it, clean up the watch.

If it's a Zenith watch that's almost 1 minute a day, it's really a bit abnormal, and you can consider repairing it.

It's normal for Zenith to have an error of more than 10 seconds a day.

This is not normal.

Mechanical watches allow a daily error of about 30 seconds, as long as the error range of about 30 seconds is qualified. If there is an exceedance, the error is a fault.

Subtle jet lag is an important issue for the proper functioning of your watch, depending on the type of watch you love.

It is normal for the normal error to be less than ten seconds per day.

Hello, a minute is not normal within the warranty period can be taken to the counter for maintenance.

In order to reduce the error, first of all, the temperature of the place where the clock is placed must be suitable, not too high or too low. Secondly, the clock should not move or move as little as possible, and it is necessary to avoid large vibrations. When it is absolutely necessary, it should also be handled with care. Third, spring your feet at regular intervals.

If it is within the warranty period, you can consider returning it, and there will be no such problem with famous watches of large brands.

The error of a mechanical watch is calculated on a daily basis, depending on the model of the movement and the quality of the manufacture, and generally within 30 seconds per day is within the normal range. Some movements with higher precision, such as the chronometer series, can reach about 10 seconds, and quartz watches can be divided into digital quartz electronic watches, analog quartz watches, automatic quartz watches and acoustic-drive watches. Quartz watches are battery-discharging, except for mechanical watches, they are all quartz watches. There is a quartz oscillator inside, which vibrates at a unique frequency when energized, so it is very accurate.

Chronometer certification (: daily difference +6 to -4 seconds, daily error of less than seconds for ordinary quartz watches.

The ZENITH watch is repaired at Room 707, 7th Floor, Tower 1, Grand Gateway Center, No. 1 Hongqiao Road, Xuhui District, Shanghai. If you encounter such a situation, you must take immediate measures as follows:

1) Pull out the watch knob and let the watch stop.

2) Never dial the needle, nor do you adjust the calendar quickly.

3) The watch is placed flat (preferably with the glass facing down), and the watch should be kept flat until it is sent to the after-sales service.

4) Do not do violent vibration and shaking during this period.

5) Tell the after-sales service of the clock, in the process of disassembly and maintenance, be careful not to let the glass chips hurt the dial and watch hands.

The watch is not allowed to run inaccurately:

1.Watch magnetization: The watch is in too much contact with items with magnetic fields, which leads to the phenomenon of magnetization of the watch, causing the watch to be inaccurate.

After being magnetized, the watch may stop, slow, or fast. After the watch is magnetized, its magnetism will not recede on its own, and it needs to be demagnetized and repaired to return to normal.

2.Lack of maintenance: If the watch lacks maintenance, it will lead to wear and tear of parts, dry up the sludge, affect the normal running time of the watch, and make the watch appear fast and slow.

3.Mechanical failures: Mechanical failures such as watch balance spring failures, escapement failures, and component slips 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. Quartz watches are generally very accurate and less prone to time failures. In the case of adequate maintenance, it is more likely to be fast and slow, which is more related to the failure of the circuit board, or the poor contact of a certain part.

Our mechanical watches often have the situation that the time is not accurate, and most people wonder if the mechanical watch is broken. There are many reasons why a mechanical watch can be parked, but there are several main reasons.

1. Insufficient kinetic energy: The watch is not winded enough, and the kinetic energy is insufficient. In particular, automatic watches require more arm movement, and the winding efficiency is very low. If you usually exercise a little bit, you can wind it manually, which can ensure enough kinetic energy.

2. Gear failure: Gear train failure such as deviation wheel and center wheel failure will lead to the condition of stealing stop of the watch. These situations are often not easy to detect and require disassembly, careful inspection and testing to find out the problem and solve the problem.

3. Lack of maintenance: mechanical watches should be maintained every 2-3 years or so. If it is not maintained for a long time, a large amount of oil sludge will be generated inside. Friction between gears increases, causing slippage.

There will be after-sales ** on your warranty link, call after-sales ** to inquire about the after-sales address.

If you find that your watch is going fast, you can find a compass to diagnose whether the watch is magnetized. Place the compass flat on the table, hold the watch at close range and quickly shake it back and forth above the compass, and try the watch in a few directions a few more times, as long as the pointer moves, especially if the deflection is very strong, you can judge that the watch is magnetized. The watch is magnetized and it is best to take it to this repair center for demagnetization.

Usually take care of the watch, do not let the watch come into contact with items with strong magnetic fields, and it is best to keep a distance of more than one meter. Do not leave your watch next to TV, computer, radio, mobile phone, mahjong table, refrigerator, washing machine, speaker, car door, or leather bag magnetic buckle.

Because there are many steel materials in mechanical watches, such as large and small steel wheels, escape wheels, shaft tenons of gears, bearings, screws and hairsprings, watches are very easy to be magnetized. The speed of a mechanical watch is controlled by a hairspring and a balance wheel. When the watch is magnetized, the magnetic force causes the frequency of the balance to swing, so the speed of the gear system also changes, and the watch may stop, slow, or fast.

If the symptoms are mild, the daily error is tens of seconds. In severe cases, the daily error is several points. After the watch is subjected to magnetic coarse potatoes, its magnetism will not recede by itself, and it needs to be demagnetized and repaired to return to normal.

Anti-magnetic watches are only the main parts, such as balances, hairsprings, springs and other parts made of anti-magnetic materials. Although it is an anti-magnetic watch, it can only play a preventive role, and it is not completely unscrupulous against magnetic fields.

In daily life, it is necessary to avoid placing the watch next to electrical appliances (such as stereos, refrigerators, computers, etc.) that generate magnetic fields, magnetic objects (such as magnets, mobile phones), and women use handbags to open and close magnetic buckles, and men use mobile phone cases to switch magnetic buckles, which may make the watch magnetic, which will cause the watch to be inaccurate or temporarily stopped.

After the watch is magnetized by hand dust, it is recommended that you go to a professional maintenance center for anti-magnetic testing and all-round demagnetization.

1. The watch is magnetized.

The hairspring is one of the most easily magnetized parts of the watch, and once magnetized, it has the greatest impact on the watch time. It is also possible to occasionally lap the loop, with the oscillation of the hairspring, it can be separated, the most common occurrence of the loop, generally between the second and third lap of the outer ring of the hairspring, to keep going like this, the watch should be at least 2 hours a day. Because of this, the watch goes fast.

2. The swing of a mechanical watch.

We know that mechanical watch movements have balance wheels, and oscillators composed of balance wheel and hairspring rotate at high speeds, but if they oscillate beyond a certain amplitude, they will collide. A pendulum, also known as a "pendulum", is a phenomenon in which the impact peg on the balance wheel hits the outside of the pallet forkhead at a high swing. The result is a drastic shortening of the oscillation cycle of the balance wheel, accompanied by a galloping horseshoe-like rush and a visible increase in the seconds hand.

Therefore, the watch goes fast.

3. The hairspring rubs against the fast and slow clamp or the outer pile.

When the balance wheel rotates, the hairspring is also oscillating, which is manifested as stretching and contraction, due to the imperfect shape or defect of the hairspring, when it is extended, it is possible that the outer ring rubs against the fast and slow clamp or the outer pile, especially in the case of high swing, which will greatly shorten the oscillation period. This is most likely to occur when the watch is located on a particular façade, and it is even more common for the watch to be subjected to severe shocks and vibrations, resulting in horizontal displacement and deformation of the hairspring. There is also a relatively rare case where a very fine fiber may be hanging on or swimming on the hairspring.

Therefore, the watch goes fast.
