1. The watch is magnetized
The hairspring is one of the most easily magnetized parts in the watch, and once it is magnetized, it has the greatest influence on the walking time of the watch. It is more typical that the stitches occur between some circles of the hairspring, that is, between the adjacent inner and outer circles. Being stuck to each other. It is also possible to occasionally take a circle. As the hairspring oscillates, it can be separated. The most common position of the circle is usually between the second and third rings of the outer circumference of the hairspring. At least 2 hours faster. Therefore, the watch goes fast.
2. The impact of mechanical watches
We know that there are balance wheels in the movement of the mechanical watch. The oscillator consisting of the balance wheel and the balance spring is rotating at a high speed. However, if the amplitude of the swing exceeds a certain swing, a collision will occur. The swaying pendulum is also called “swinging”, which is a phenomenon in which the impact nail on the balance wheel hits the outside of the escapement fork in the case of high swing. The consequence is that the oscillation period of the balance wheel is greatly shortened, accompanied by a rapid sound like a horse-shaped horseshoe, and the second hand runs faster. Therefore, the watch goes fast.
3, the hairspring to the speed clip or the pile above the
When the balance wheel rotates, the balance spring also oscillates, which is characterized by stretching and contraction. Due to the imperfect shape or defect of the balance spring, when it is stretched, it is possible that the outer ring is smashed onto the fast and slow clips or the pile, especially at the high swing. In this case, this will greatly shorten the oscillation period. This situation is most likely to occur when the watch is on a particular façade, and the watch has been subjected to severe shocks and vibrations, and the spring has produced horizontal displacement and deformation, which is more common. There is also a rare case where the fine fibers are licked on the top of the hairspring when it is hung or swimming. Therefore, the watch goes fast.
