What should I do if the time of the automatic mechanical watch is not allowed?

2023-03-23

One of the characteristics of automatic mechanical watches is that the time is not accurate enough, although many watch factories can greatly improve the accuracy of mechanical watches technically. But inaccurate travel time is still an unavoidable problem for mechanical watches, so how do we deal with an inaccurate travel time of mechanical watches?

Regarding the travel time error of automatic mechanical watches, first of all, you need to know the following two points:

1. The accuracy of automatic mechanical watches cannot be maintained through calibration

Because the travel time of an automatic mechanical watch is constantly changing, it can be temporarily accurate in a spring state, fixed position, and temperature environment, but it will change compared to another situation. That is to say, even if the watch is calibrated to be exactly one second, it will not be maintained, and the accuracy will always change in an instant and fluctuate.

Moreover, there are many other factors that affect the accuracy of the watch. The error of the watch we see is only the average error of actual travel and unit time.

2. The accuracy of the automatic mechanical watch is best when the mainspring is fully wound

To keep your watch accurate, you must wind up the mainspring as fully as possible, which is even more important for automatic watches. Because the tightening degree of the automatic watch spring is directly related to the wearing time and wearing movement, the premise is that there must be a sufficient amount of exercise.

Generally speaking, the travel time error of automatic mechanical watches may be caused by the following reasons:

1. Insufficient power reserve

You need to check whether the power is sufficient first. If the amount of exercise of the automatic winding watch is small, the power reserve may be insufficient. You can replenish the power by manual winding, and then observe whether the phenomenon of speed continues. If it is a manual winding movement, it is very likely that your arm is not moving enough. Because the manual winding movement is powered by the swing of the arm, people who sit in the office for a long time and the elderly are not suitable for wearing it. Unless it is a particularly fanatical watch lover.

2. The watch is magnetized

There is a part of the watch called the hairspring, which is most afraid of the magnetic field. When the watch is close to the magnet, the hairspring will be magnetized. After the hairspring is magnetized, the hairspring will bond together, which can affect the accuracy of the watch at least, or stop at worst. After the watch's hairspring is magnetized, it is necessary to find a watchmaker to use a degaussing instrument to demagnetize the watch, so that the watch can return to normal.

Prevention and solution:

Electrical appliances with coils will generate alternating magnetic fields, such as hair dryers, motors, and transformers.
When you take a steel metal object, when you get close to them, your hand will feel a vibration, and it is easy to obtain an attenuated alternating magnetic field. In fact, it is achieved by holding the watch close to it first, and then gradually moving away. This is an earth method, please try it carefully. Usually, it can be demagnetized, but the demagnetization is not clean.
It is recommended to go to a professional watch repair shop for demagnetization.

3. Need maintenance

The lack of oil in the movement or the wear and tear of internal parts may cause travel time problems, and it needs to be sent to a designated repair point for maintenance services. Mid-to-high-end watches should be maintained every two to three years, such as replacing waterproof components, testing travel time performance and power consumption of the movement, cleaning the movement, and maintaining the appearance.

4. has been hit or hit

The watch is very precise, if it is hit or beaten, it may cause loosening and damage to the internal parts, and it may also cause travel time problems. In addition to the above common situations, the influence of some environmental temperatures and the influence of the wearer's usage habits may cause an increase in travel time error.

There are many reasons for the inaccuracy of mechanical watches, but there are two main categories: one is that the movement is damaged, and the only way to deal with this is to send it to the relevant parties for repair. The other is that it is gradually inaccurate due to the influence of the environment and the way of use during long-term use. The ultimate solution is to send it for maintenance, but as long as the problem is not too serious, it can be used temporarily. The thing to consider here is whether you can try degaussing if you go a little faster. As long as the master has the equipment, it is immediately advised to raise your hand. In addition, in extreme climates and extreme use environments, the operation should return to normal after returning to the normal environment, and no special treatment is required. After long-term use, mechanical watches tend to run inaccurately, especially those antique watches. This situation is more obvious and must be sent for maintenance. As for whether to maintain regularly or how long the period is good, personal opinions are not fixed. It is not too late to deal with the obvious speed phenomenon. One reason is that different styles of watches and watches in different usage states will have different damages, and it is not scientific to generalize. In addition, opening the cover for maintenance also increases the risk of damage to the movement, and it is expensive to pay, so there is no need to deliberately maintain it for maintenance.
