The Common Fault Of Automatic Mechanical Watches

Time:2019-03-18 Views:243
The common fault of automatic mechanical watches is that the walking time is not accurate, especially when the watch accidentally falls to the ground, the gravity acceleration, the damage caused to the watch is very large.
Possible damage, one is the appearance of the watch, such as: the case is bruised, scratched, the watch is skewed or the watch glass is broken; the other is inside the watch, including the dial deformation, the characters fall off, the hands fall off, the night falls off, in addition There are also movement parts.
       In the watch movement parts are the most "squeezing", when it belongs to the balance wheel and hairspring. The balance wheel is because its axis is very thin, about 0.10mm. 
The balance wheel rotates in the watch at high speed, and the whole mass of the balance wheel is supported by it. Today‘s brand watches are equipped with shock absorbers, which can effectively protect the balance shaft from being damaged when the watch is strongly shaken.
       The spring in the movement is actually a tiny spiral spring, the shape of which is called the Archimedes spiral. It took about 10 laps and was made from a nickel-based material with extremely complex composition. It is the most important part in maintaining the mechanical oscillation of the balance. Its installation, adjustment, shape, clearance in the speed clamp and Omega watch rippling are the most important part of determining the accuracy of the watch.
The rigidity, spacing and number of turns of the hairspring are related to the oscillation frequency of the watch and the size of the movement. Generally speaking, if the frequency is low or the female watch, the hairspring is relatively "soft". On the contrary, the higher the frequency, the more "hard" the hairspring is.
In the early "slow pendulum" watch (18,000 times / hour), after the watch was hit, the hairspring was most prone to "hanging". That is to say, the inner ring of the hairspring is hung on the top of the hairspring or the clip. It usually means that the watch is very fast when it stops or walks.
Today‘s watches, the frequency is mostly 28800 / hour of the frequency, the hairspring is relatively hard, the spacing is also small, after the watch is dropped, the problem that the hairspring is prone to deformation is deformation. The so-called deformation means that the level of the hairspring is cheaper than that of the Tissot watch, so that the hairspring becomes uneven or not round. Among them, the horizontal deformation is the most, and the hairspring is different. Also, it may hit the gossip pile during the wandering of the work. The fault manifests itself as that the watch is easy to stop and the time is faster. The specific speed depends on the degree to which the hairspring is released to the outer pile. Seriously, it can be as fast as 2 hours a day.
Many watches that have been repaired (especially ETA movements) have found that the hairspring is horizontally displaced and deformed without exception, and that the second loop of the hairspring has reached the top of the hairspring. In the repair, you need to use the tweezers to make a careful correction to the hairspring, be sure to ensure the concentricity, to ensure its pitch, peace and round.
If you find that the watch has been accidentally dropped, there is a very fast phenomenon of walking and stopping and accompanying time changes, and most of the time, the hairspring is deformed. Of course, it is also possible that other components also fail at the same time.
Today‘s custom watches are getting bigger and bigger (watches have this trend), many men‘s watches are approaching 50mm in diameter, and the weight is getting heavier. If you use a solid stainless steel strap, it will have about 130 grams.
