At one time or another, every watchmaker has had trouble with magnetism. Not much is known about where it comes from — it often occurs when no magnetic field has been contacted to the knowledge of the owner — and not much is known about getting rid of it.

In view of the present methods employed so successfully, this last statement may sound farfetched. But it is not. Every experienced workman has found, at one time or another, a watch magnetized in such a way that ordinary methods would not take it out.

The usual method is to place a small compass over the watch suspected of magnetism. Turn the watch slowly around and watch the compass. If the balance wheel is magnetized, when the compass is directly over it the needle will rock back and forth with the swinging of the wheel.

Another time it may drop directly down toward the wheel and stick in that position. On still other occasions, the compass may not be attracted to the balance but to some other part of the watch such as the stem, the crown wheel, or even the mainspring. All these things indicate magnetism.

The simple way to remove it is with a demagnetizer which may be had from your supply house. Simply insert the watch in to the coil, press the contact button and pull the watch away at the same instant. Hold the watch on an even keel and hold the contact button until the watch is approximately three feet away from the machine. Release contact. Never at any time hold contact button more than ten seconds.

Now try the compass again. Perhaps that one effort removed it. If not, try again. Many times you must turn the watch to different positions. Perhaps the stem is magnetized. If so, it must come out through the watch. Therefore, the stem must go into the demagnetizer first, If it does not work one way, try it another. The best of demagnetizers will have to be worked with in order to remove all traces of magnetism.

Another thing to remember is this: a balance wheel that is heavily magnetized cannot be poised. Perhaps because the magnetic pole attracts the wheel such as it does a compass. So if the wheel will not poise, try the compass on it. If it is magnetized, you must remove it before continuing with the poising.
