Is it normal for a mechanical watch to be 0 1 second faster in a minute?

24 hours a day, 60 minutes per hour, so a total of 1440 minutes a day, every fast second per minute, the day will be 144 seconds faster, and the international mechanical watch day error is within plus or minus 30 seconds, so this is abnormal.

Hello. The method of adjusting the speed of the mechanical watch: 1. First of all, rotate the watch counterclockwise, and find that it pops up after a few turns, which is in the winding state at this time, and can be wound by tightening clockwise.

2. Then, pull the watch out of a grid, and adjust the date status, if it is only one minute faster, the date is accurate, then there is no need to adjust. 3. Pull the watch out of a grid again, and at this time it is in the state of dial time adjustment, which can be adjusted as needed. 4. Finally, press the watch to its original position and you can wear it.

The reason: the balance wheel inside the movement is too heavy, and the balance wheel is unbalanced, which is what we often call the balance wheel is too heavy, which will directly produce position errors. Because the oscillating shaft of the balance wheel needs a clearance, and it is precisely this clearance that is actually the reason for the random bias.

Solution: Generally, in the production process of watch parts, the balance wheel is statically balanced; During the assembly of the movement, the balance wheel is adjusted again to greatly reduce the position error and improve the overall performance.

The "tourbillon" structure was also created for this purpose, in order to improve the effect of the balance wheel imbalance on the accuracy of the clock by rotating the escapement.

Special method: When the balance amplitude is stabilized at 220°, the various impact forces transmitted to the balance have no effect on the frequency. Using this principle, some people have tried to control the swing around 220° by using an equalizing mechanism mounted on the escapement, but it is very difficult to achieve.

A mechanical watch error of 30 seconds is considered normal. Generally speaking, as long as the mechanical watch is in the case of full winding, the time is not more than 30 seconds slower and no more than 30 seconds fast every day. The instantaneous error range of the calendar mechanical watch type I (men's watch) is:

Superior error per 24 hours -30 +45 seconds; First-class error -40 +75 seconds per 24 hours; The error of the qualified product is -60 +105 seconds per 24 hours. The average duration of the continuation is greater than or equal to 36 hours.

The instantaneous error range of the calendar mechanical watch type II (medium-sized watch) is: -35 +65 seconds per 24 hours for the superior product; First-class error per 24 hours -50 +95 seconds; The instantaneous error range of the qualified product is -70 +135 seconds per 24 hours. The average duration of the continuation is greater than or equal to 35 hours.

Precautions for purchasing a mechanical watch.

When buying a mechanical watch, pay attention to check whether it can swing automatically. The method is to gently hold the watch that relaxes the stop of the spring, slowly wind it, and at the same time look at the second hand, which should be rotated at the beginning of the winding clockwork, otherwise it is not standard.

Missing call checklist sounds in various locations. After a few springs, turn the surface upwards, downwards, left, and right. Listen to the frequencies and beats in all directions, and after winding up, the sound is crisp and noise-free.

It is normal for a mechanical watch to have a daily error of less than 30 seconds. Due to the different internal mechanical structure of each type of watch, under normal use, the error of mechanical watches or mechanical automatic watches is within 30 seconds per day (this standard is promulgated by national ministries and commissions), while the error of quartz watches is lower and more accurate. Mechanical watches are larger than quartz watches, and errors occur due to the quality of the production and the fact that the core inside the watch is susceptible to the influence of gravity.

Usually mechanical watches are calculated in terms of daily error seconds, while quartz watches are calculated in terms of monthly error seconds. If you want to be accurate and timely, and finally replace the electronic watch, the mechanical watch needs to be calibrated and timed at regular intervals during wear.

Summary. Abnormal mechanical watch is powered by the mainspring, relying on the balance wheel speed regulation system to control the operation of the watch, its timing accuracy is affected by many internal and external factors, for example, it is easily affected by temperature and humidity changes, the spring full or half string, external force caused by swing, vibration, magnetism, etc., is caused by mechanical characteristics. In order to ensure the accuracy of the watch, the maintenance cycle of Citizen mechanical watches is generally about 2 years, and regular watch maintenance can ensure the sealing effect and waterproof performance of the watch.

There are two ways to adjust: First, it is to correct the standard time every day.

2. Open the back cover and adjust the frequency of the balance.

Is it normal for a mechanical watch to be about a minute slower every day?

Automatic. Mechanical.

People are at most a minute or two slower a month.

It's not normal for you to be a minute or two slow down this day.

It is recommended to find an after-sales service and let them repair it for you.

It doesn't matter if this is the case, you can continue to use it. The mechanical judgment table has an error of 10 seconds a day, which is not a fault, it is an error within the controllable range of a liter of punching die, because the mechanical watch is manually debugged, and the error within plus or minus 20 seconds every day belongs to the normal range. Generally, the operation of mechanical watches is generated by the rotation of the mainspring inside, and the mainspring is slow in the case of looseness or tightness, which will cause an error in operation, as long as this error is not more than 20 seconds a day, it does not matter, you can continue to use.

Hello, it is normal for a mechanical watch to be ten seconds slower a day. It is normal for mechanical watches to have errors, and the reasons for the errors are: 1. Due to the level of the watch, according to the international standard automaton The instantaneous error range of the watch I-type is as follows:

Superior products have an error of 20 to 30 seconds every 24 hours; First-class products have an error of 30 to 60 seconds every 24 hours; The good product has an error of 50 to 90 seconds every 24 hours. The average duration of the continuation is greater than or equal to 36 hours. 2. Due to the owner's wearing habits. Mechanical watches should be worn regularly so that the gears between the movements can be fully integrated.

When the first fiber base finds that there is a major deviation in the mechanical watch, the first thing to check is whether the seal of the outer box of the movement is intact. Each time you adjust the time of a mechanical watch, twist the crown clockwise.
