What is the normal error of a mechanical watch
For the love party, quartz watches and mechanical watches have their own advantages and disadvantages. Quartz watch time accurate, people who know the watch may know, quartz watch and mechanical watch movement is completely different, quartz watch core belongs to the electronic structure, the vibrating body is quartz, quartz has a fixed frequency of vibration, to ensure that the time is accurate. The biggest disadvantage of the machine is that there will be an error in walking time, today let me introduce you to the mechanical watch error how much is considered normal as well as the normal error range of mechanical watches!Article from watchdetective replica - https://www.bbtwatch.com/en/wbzs/61893-html

First, how much error is normal for mechanical watches.Article from watchdetective replica - https://www.bbtwatch.com/en/wbzs/61893-html
Generally speaking, the daily error of the automatic mechanical watch is allowed within ± 30 seconds, while the error of the chronometer certification is more demanding, the average error is -4 seconds to +6 seconds / day, the power of this automatic mechanical watch comes from the movement of the arm when wearing, driving the oscillating weight to rotate the watch to wind up the watch, generally in the state of the full chain, the mechanical watch can be in 36 hours to keep the time. If you wear it under normal circumstances, the normal use is about 16 hours. Work if you do not bring for a long time, or sit on the arm for a long time with too little movement, the watch may stop using. Therefore, to keep our automatic mechanical watches within the normal range, we have to wind the watch in our daily life.Article from watchdetective replica - https://www.bbtwatch.com/en/wbzs/61893-html

According to our watch industry standards, self-winding men's mechanical watches with a daily error of between -30 and +45 seconds are considered superior; -45 to +60 seconds are considered first class, and 60 to +75 seconds are considered qualified. Of course, watchmakers put a flywheel mechanism into the movement to minimize this error. In foreign countries, such as Longines, domestic brands such as Erbo Yufei, is to use this method to reduce the time error. How much error is normal for mechanical watches, I suggest that watch lovers communicate with professional watch repairers. They can answer the questions of those watch lovers very well. Hopefully, all these can be helpful to watch lovers!Article from watchdetective replica - https://www.bbtwatch.com/en/wbzs/61893-html

Mechanical watches how to prevent the error from increasingArticle from watchdetective replica - https://www.bbtwatch.com/en/wbzs/61893-html
The principle of movement of the machine is mechanical rotation, powered by the clockwork, and the large oscillating weight keeps rotating to achieve automatic winding. And because of the internal mechanical type of clockwork tightening and loosening state, the core wear condition, position change, temperature, electronic devices produce magnetic field, etc. caused by mechanical transmission unbalance error. Even if the watch is adjusted to one second is not a bad thing, mechanical watch is not always possible to maintain, so the accuracy will change over time.Article from watchdetective replica - https://www.bbtwatch.com/en/wbzs/61893-html
1. The power of the machine watch relies on the arm movement to realize the operation of the link on the watch, generally around 25-30 circles, in the state of full chain, the ordinary mechanical watch is able to maintain 36 hours of walking time, and it generally takes about 16 hours. If the working time is too long, or if the watch is sedentary while working, or if the amount of arm movement is too little, the watch is likely to stop. In order to prevent the watch from stopping due to lack of power, it needs to be wound manually for about 25-30 turns.
2. Daily habits, adhere to the movement, if not worn for a long time, it is as if you want a few mechanical watches, every day to replace a few mechanical watches, for the more expensive watches, it is recommended to use the shaker, so that the mechanical table every day can work properly, a long time does not work the mechanical table or walking stops and so on, there is no benefit to the movement itself.
3. Their own maintenance is also very important to reduce the bump, general life waterproof watch as little as possible into the water, can not put magnetic items.
What causes a mechanical watch not to run correctly?
Due to a series of influences, mechanical watches can not reach the degree of accuracy. Machine table type, manufacturing quality varies, ordinary table daily error of 30 seconds or less, are within the normal range. Some higher precision core can reach 10 seconds. The following gives you an explanation of the reasons why mechanical watches are not allowed to walk.
1. Magnetic field effect.
Many parts of the mechanical watch movement part are steel structure, so they are easily magnetized. When the mechanical watch is in the external magnetic field or has been magnetized, the oscillation cycle of the balance wheel will be interfered by the magnetic force, which is manifested as very fast timekeeping. Therefore, in daily life, it is better to keep mechanical watches away from refrigerators. Speaker. Cabinet door and other household appliances with permanent magnets.
2. Rationale for power storage.
The mechanical action of automated winding is mainly generated by the wearer's wrist movement, therefore, when the wearer does not wear it during daily work or for a long period of time, the string force will drop or become empty, resulting in the watch not being able to walk or stop when walking. In that case, the wearer can manually wind the watch according to his/her preference (10~20 rotations in a clockwise direction to manually wind the watch).
3. Improperly fitted.
When people wear a watch, some of their own behavior behavior will have an impact on the watch, such as swinging the wrist with force, so that a part called the hairspring is entangled. This causes the watch to go faster or even stop running; if the watch is subjected to a large shock, it will make the watch jump out, the shock absorber fall off, and the fast and slow pins are misplaced. Watches are often subjected to strong impacts, and the winding efficiency decreases or even fails.
Also, although most watches are water resistant, if the watch is not very water resistant, try to remove the watch when it comes into contact with water. To ensure water resistance, even professional waterproof watches should be replaced at least once every two years.
4. Maintenance issues were not considered.
Clocks and watches belong to precision instruments, and their internal mechanical structure is very strict and fine. Therefore, due to the long time operation will lead to screws loosening. Insufficient oil and other problems, these problems will affect the operation and service life of the watch, so mechanical watches need regular maintenance.
Can the error of a mechanical watch be adjusted?
The permissible daily error of an ordinary mechanical watch is about 30 seconds, and the specific error depends on the movement used in the mechanical watch, such as there is no too clear regulation on the error of the watch, which is based on the national standard. Since the error of mechanical watches is larger compared with quartz watches, the adjustment of mechanical watches is particularly important.
Mechanical watch timekeeping error standard, can be corrected?
Machine position error criteria:
Men's Mechanical Watches
Best (sec/day) -20 to +30 First Class (sec/day) -30 to +60 Qualified (sec/day) -50 to +90.
Women's Mechanical Watches
Optimal (sec/day) -30 to +40 First Class (sec/day) -40 to +80 Qualified (sec/day) -90 to +120.
Machine meter tuning time slot selection:
1. Daytime jump schedule can be adjusted, such as found in the schedule in the day between noon jump, usually table time fast. Slow 12 hours, for example, in fact, it is now 11:00 a.m., the watch is the previous day's 11:00 p.m., just add the hour hand in the table, that is, the afternoon changed to the morning. This is a relatively common condition, with a chance of about 50%.
2. In order to prolong the service life of the watch, many watches use a gradual jump around midnight, usually completing the jump before 2:00 am, and partly not until 4:00 am. For example, I am wearing this Seagull M186SP.
3. Please do not adjust the time at 22:00-2:00 (20:00-4:00 for some watches), which will easily lead to damage to the watch or the calendar jumping wrong. In other words, the afternoon laboratory mechanical watches recommend that people try to adjust the time during the day.
4. Adjustment methods vary by watch style, but when adjusting a watch with a schedule function, AM and PM must be taken into account.
5. The general mechanical watch adjustment requires clockwise pulling out, such as counterclockwise pulling out, it will make the watch pointer deviation. Special attention should be paid to this, usually worn with the left hand, adjusted with the right hand, and turned forward in the clockwise direction.
