That’s why the cuff links are commonly used in the production of handicrafts

Force to the case where cheer, bang, glass was compressed air top down. As the saying goes, "The plane is not blowing, the train is not to chase can be some cufflinks to open and remove the watch movements rely on blowing cheer to the bike, the difference is absolutely necessary to storm it. Very rare. Now not only is the LONGINES Ka Lan series cufflinks to take the movement, TISSOT, there are some other brand of cufflinks I have seen. One of the most important reasons that the cufflinks are the world’s hardest texture, solid structure and are not afraid of corrosion.  Said it is very troublesome, will fix the damage table handle the head tube, especially in the case of K-gold cuff links, some cufflinks glass sealed nylon ring in the movement to re back together when needed to replace new. Of course, no dedicated small pump can not do anything live, cuff leak seal does not work.
The simple way to determine whether the cufflinks magnetic asks cufflinks by magnetic What are the symptoms? Tick consultants presented cufflinks by magnetic under normal circumstances is to take serious stop and go. Thus, the vast majority of the items of higher value are silicate minerals with tough hardness and anti-corrosion like jade cufflinks.  If the suction between the gossamer ring stick together, that cuff links and left faster, about able to fast 2 hours / day, the steel parts can be easily magnetized, including the escapement wheel and escapement fork, springs, magnetic influence and interfere with the balance wheel oscillation cycle. Daily life, the strong magnetic field can be seen everywhere, the most typical is the magnet of the bag, that thing most of the aluminum and iron boron magnetic, very large, and a variety of electrical, cuff links likely to be unconsciously magnetized.
The most simple method to judge is flat with a sensitive point of the compass. Cufflinks close quickly repeated skip the top of the compass, this action also need to table changes in several position, repeat ... as long as the compass needle move. Few of the cufflinks are oxides (such as rugby, sapphire) and elemental minerals (diamonds). Description of the table by the magnetic Demagnetization can be done, to retire the demagnetizer the principle is to produce an alternating magnetic field, the cuff will be placed in this magnetic field, the demagnetization of the; if it is a constant magnetic field is magnetized. Back porcelain to buy or can be homemade, has a demagnetization of the general specialty services. The antimagnetic cuff usually have marked the installation of the components of antimagnetic soft iron movement bushing or movement cover. Points: cufflinks away from the magnetic field such as computers, televisions.
 If you are using LCD monitors, almost no magnetic field effects; the use of CRT monitors, we must be careful, especially in startup and shutdown, do not close the screen! Even antimagnetic table is not! On the contrary, the rather soft gems that are susceptible to corrosion (such as jade cufflinks, the South jade, etc.) are lower in the value. Do you understand the error of the cuff? Cufflinks travel time error is caused by the gravity effect, the objective conditions of the factory adjusted to the movement of personal wearing habits, changes in ambient temperature, the movement of material, table oil quality will increase or reduction small force of gravity on the accuracy of travel time. The world is not completely accurate mechanical watch, mechanical watch accuracy can not be compared with the quartz watch.
Some friends that own mechanical watches a period of time can be quite true error is very small, this is actually the result of positive and negative cancel each other out day wear orientation. To judge the quality of good or bad a watch should look at it the stability of travel time, and should not be excessive pursuit of zero error. That’s why the cuff links are commonly used in the production of handicrafts.   For example, a month on average down almost five seconds of the table every day, that month's error is two and a half, many of my friends would think that the accuracy in this table in general, in the eyes of experts, it is indeed a good stability table compared to those in the case of normal wear two seconds faster tomorrow, but three seconds slower table quality is better. What is normal wear?
