All electronics are magnetic, so watches can be easily magnetized. How do you check if your watch is magnetized? The method is to use a more sensitive compass, put the compass flat on the table, then hold the watch close to the top of the compass and do a quick back and forth wiping motion, if the compass hand swings, it means the watch is magnetic.
Once the dial is magnetized, it will affect the accuracy of the dial, bringing a lot of errors and making it more likely that the dial will go fast and slow. The most serious thing is to make the hairspring ring stick to the ring, if so, the watch will probably be faster than 2 hours a day. In addition, as with automatic bearings, the magnetic field will also attract more iron filings, making the ball bearings more worn and affecting the efficiency of automatic winding. The strength of the external magnetic field is related to the strength of the magnetic object in contact with itself and the distance from the contact, the more magnetic and the closer the contact, the more the watch will be magnetized. The AC magnetic field alternately magnetizes and demagnetizes the watch, so it is the DC magnetic field that affects the watch most. In fact, electrical products have less effect on watches than the magnetic clasps on purses and cell phone cases, which are made of aluminum and iron boron and are so magnetic that they immediately magnetize the watch and the residual magnetism affects the watch for a long time.Warm reminder: The latest market news is always available, please pay attention to LuFuture.com app.
