All electronic products are magnetic, so the watch is easily magnetized.
How to check whether there is a magnetization phenomenon of their watch?
The method is to use a more sensitive compass, put the compass flat on the table, and then hold the watch, close to the compass above, do a quick back and forth wipe action, if the compass pointer swing, it shows that the watch has a magnetic.
Dial once magnetization, will affect the dial travel accuracy, bring a lot of error, the dial to go fast and slow possibility.
The most serious is to make the spring ring and ring adhesion, in this case, watch every day about 2 hours faster.
In addition, like the automatic bearings, the magnetic field will also absorb more iron filings, which will aggravate the wear of the ball bearings and affect the automatic winding efficiency.
The strength of the external magnetic field and contact magnetic things are related to their own magnetic strength and contact distance, the greater the magnetic, the closer the contact distance, the watch is magnetized is more serious.
If it is an alternating magnetic field on the watch is alternately magnetized and demagnetization, so the impact of the earth or DC magnetic field on the watch.
In fact, the impact of electrical products on the watch is not as good as those bags, mobile phone cover on the magnetic button, that thing is aluminum iron boron do, magnetic huge, the watch is immediately magnetized, magnetization after the magnetization will affect the watch for a long time.
The latest market dynamics at any time to see, please pay attention to.
