First of all, mechanical watches are error-free, and the national standard is normal within 30 seconds of plus or minus 30 seconds for 24 hours. The International Astronomical Observatory's time service standard is within plus or minus 5 seconds in a 24-hour period.
-
Mechanical watches will have errors, as long as they are within the allowable error range.

Reasons why the watch is not running accurately:
1. Insufficient power reserve. You need to check whether the power is sufficient, if the amount of movement of the automatic mechanical watch is small, it may also cause insufficient power reserve, you can supplement the power by manual winding, and then observe whether there is a continuous phenomenon of speed and slowness, if there is still a suggestion to send it to the after-sales center for testing.
2. The power is insufficient. If the quartz watch suddenly finds that it is slowing, it is likely to be caused by insufficient battery energy, and send the watch to the after-sales center to check the battery or replace the battery.
3. Having been beaten or impacted. The watch is very tight, if it is hit or fallen, it may cause loose damage to the internal parts, and it may also cause time problems, it is recommended to go to the after-sales center for testing.
4. Maintenance is required. The lack of oil in the movement or the wear and aging of the internal parts may cause time problems, which need to be serviced and sent to the after-sales center for maintenance services.
5. 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 it to the after-sales center for inspection and adjustment can restore the watch to the normal error range.

For Mido. If the date is only inaccurate due to the lack of power of the Mido watch, you only need to swing the watch dozens of times or a few times to adjust the time. To ensure the Mido mechanical watch.
Walk accurately and wear it normally for more than 8 hours a day.
2. The watch is not allowed to be affected by the surrounding magnetic field, if the watch has been affected, the watch can be sent to a professional watch repair shop for demagnetization.
3. In order to ensure the normal operation of Mido watches, the watch should be sent for maintenance regularly, waterproof test and appearance cleaning can be carried out once a year, and the whole machine maintenance of mechanical watches should be done once every 3 to 5 years, which can not only keep the watch in good running condition, but also prolong the service life of Mido watches.

A watch with a calendar (including a day of the week) function, its watch handle has 3 gears, when the watch handle is fully pushed in, it is a normal gear", rotating the watch handle can wind the watch, when the watch handle is completely pulled out, it can be adjusted forward or backward, between the "normal gear" and the fully pulled out dial hand, there is also a gear, which is used to quickly adjust the watch calendar.

For the Mido watch now that the date is inaccurate, I think he should adjust it, so as to reflect the quality of this watch, after all, it has been worn for too long.
-
What should I do if the date of my Mido watch is inaccurate? I think that under normal circumstances, the date of the Mido watch is not accurate, and I said that you can uh adjust it from the inside of the watch, maybe it will do.
-
What should I do if the date of my Mido watch is inaccurate? I think that if the date of the Mido watch is not accurate, this should be readjusted.

Generally speaking, mechanical watches (including automatic mechanical watches) basically meet the standard as long as they are slow down by no more than 30 seconds per day and no more than 30 seconds faster than when the battery is full.
Except for the screen chip electronic watch, the watch that never beats the second actually does not exist, whether it is a mechanical watch or a quartz watch has a margin of error, and this range varies from country to country.
Therefore, whether it is a mechanical watch or a quartz watch, as long as the error is within the range of the above two standards, it can be said that the watch is qualified.
Otherwise, it means that there is a problem with the watch and it must be taken to the repair and maintenance department for adjustment.
Hello, you can consider it from the following aspects:
1. 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. >>>More
