They're real.

I have not had problems with watches becoming seriously magnetized (that is, off by hours per day), but I have noticed that movements are susceptible to being slightly magnetized, with magnetization changing their rate by 5 - 10 seconds per day. Some movements are more susceptible than others. Obviously, for a watch that doesn't keep good time to start with, one will never notice the difference.

Ironically, my biggest cause of magnetization seems to have been a couple of watch winders. They didn't magnetize watches that they were winding, but they seemed to be shielded only in that direct, so leaving a watch near them would tend to magnetize it.

Hi All, This may have been done to death.... certainly touched on in many posts..... but have any of you had problems with a modern watch becoming magnetized to the point that it needs rectification. I can only say that I have never had a problem with Rol...

definite issues for me

By: sancerre : October 27th, 2009-14:15

I have definitely had issues with laptops and automatic watches. I owned quartz watches for years without issues. Over the past couple of years I have tried two Oris models, and a Jaeger le Coultre. All three of them proved to be unreliable due to magneti...

Thanks... How can you tell if a watch becomes magnatized....

Hi and thanks for your reply.. How can someone tell if a watch becomes magnetized. kindest regards, Jack

by observation or w/ equipment

By: sancerre : October 28th, 2009-08:35

It was really easy for me, all of the watches suddenly and dramatically lost accuracy. For example, instead of gaining a few seconds a day, gaining nearly a minute a day. If you take the watch to a dealer, they can easily detect if if has been magnetised ...

Hi Amerix...How do you demagnetize a watch

By: justpen : October 29th, 2009-06:34

Hi Amerix Tell me how do you demagnatize a watch. Kindest regards, Jack

by banging it on a table

By: amerix : October 29th, 2009-11:31

Well, what I do is to bring a simple and cheap "throttle" or inductance coil - one I have frequently employed to demagnetize the heads of tape and cassette reorders - by first plugging this longish oval device, with no moving parts, and which fits easily ...

Thanks Amery... I am now a wiser and happier man..

Hi Amery, I am now a wiser and happier man.... . I am sure many screwdrivers have been pointed north and banged in the last 24 hours. kindest regards, Jack

Magnetic and soft inner core?

By: iceheller 1945 ✌️ : October 30th, 2009-02:32

I own a BALL WATCH Engineer HydroCarbon which uses the soft inner core to give the watch more shielding against magnetic effect. I constantly place my watch around labtop and some time stand infront of loud PS15 Nexo speaker and they still work fine. The ...
