Magnetic Errors
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 Rolex or Omega over a 30 year period. I have also been working with and close to strong magnetic fields during that time.
Further, I believe that modern materials are not prone to magnetic influence.
I am aware of the 'Soft inner iron core" marketing by one maker, but I think that is an unnecessary cure, for a cold that you might never catch.... unless you work in a power generating plant or magnet factory.
Certainly, if buying a gold watch I would prefer to know that the weight I feel is from the gold case, not an inner iron case, back and dial.
I can understand that early watches right up to the mid to late 1900s had a lot of steel parts in addition to the steel springs, and they 'Might" build up some magnetic energy.
I also remember as I was growing up in the 60's that for a while on radio and TV advertising, just about every watch was marketed as 'Anti Magnetic' ..... and I am sure they did not have inner iron cores.... but those same adds boasted of watch's having 7 or even 9 jewels....WOW...... so also they were obviously not what we would consider HH.
So realistically.... with modern metals.... what are the chances of a watch becoming unreliable due to magnetic exposure?
Kindest regards,
Jack

definite issues for me

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...

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 move...

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 ...
