■OnePoint advice!
A natural enemy of watches that many customers ask questions about. "Magnetic"
This is a very common cause of delays, progress, and stoppages.
This"Magnetic"The trouble with this is that you can't see it.
Therefore, most customers have no recollection of when magnetic interference occurred.
Magnetic bands are difficult to deal with from these points, but if you are careful, there are ways to deal with them! !
■Effects of magnetism on various watches
・"Mechanical watch"(self-winding watch, hand-winding watch)
The internal parts of the movement are made of metal, and if exposed to strong magnetism,parts are magnetizedI end up doing it.
Inside a mechanical watch, there is a device that controls the speed at which the mainspring unwinds."Temp"There is a part called.
The balance acts like a pendulum, moving evenly from side to side.Magnetism affects the precise movement of this balance wheel.、This may cause the clock to become less accurate or stop working.。
・"Quartz watch"(Battery watch, solar rechargeable watch, etc.)
Analog (hand-type) quartz watches utilize the properties of magnets."Step motor"There is a device called Permanent Magnet.
Therefore,If it is exposed to strong magnetism, it may stop, time may slow down, or it may move forward.
*As mentioned above, if both mechanical and quartz watches are affected by magnetism, various negative symptoms such as delays, advances, and stoppages will occur.
In the case of quartz, if the magnetism is light,Just keep your distance from magnetic fieldsIn most cases, the current state can be restored by adjusting the time, but in the case of mechanical systems, once the parts become magnetic,I have to disassemble and clean it and remove the magnetism.In many cases, it is not possible to return to the current situation.
Of course, in the case of quartz, if it becomes strongly magnetic without you noticing, you will have to replace the machine or disassemble it for cleaning.
■Why does this happen?
Next, let's take a look at what kinds of objects actually generate magnetism and affect watches!
There are various reasons for this, but there is a possibility that you may become magnetized without knowing it.
As mentioned above, we have listed the strength of magnetism of things that are around us and can bring a watch close to it without our knowledge.
Approximately for a typical ordinary watch1600A/mIt is said to be resistant to magnetic fields.
So, as you can see from the table, if you put them in close contact, they will immediately be affected by magnetism that far exceeds their resistance.
■What should I be careful about?
just a littleJust keep it 5cm away!is!
You can see that just by doing that, the strength of the magnetism is significantly reduced.
further thisIf you move it 5cm away and make it 10cmThe durability of the watchBelow 1600A/m, it will no longer be affected by most magnetic products.
①First, understand the things around you that generate strong magnetism.
②Also, be careful not to place your watch within 10cm of the object.
However, it is still invisible, so it may be difficult to prevent all of it outdoors.
However, if you understand this in your daily life and take some precautions, I think you can prevent magnetic interference to a large extent.♪
■Not magnetic!? About “magnetic resistant watches”
There's one more thing left.
Just like there is a waterproof watch on a wristwatch.anti-magnetic watchThere is also such a thing.
Just like waterproof performance, magnetic resistance ranges from those that can withstand normal use to those that can be used in close contact with any type of magnetism, so if you are interested, you may want to check it out!
There aren't as many as waterproof watches, but I think you can get a feel for the commitment each manufacturer makes.
Above, I have talked about the relationship between watches and magnetism.
I hope you find this useful as a reference when handling your precious watches (^^)
