I guessed if the distance is too near to the magnetic field, doubt...
the soft-iron case would be able to withstand. I also think the exposure time play a part too.
Do re-read John's ( ei8htohms) post, his friend's watch has a soft-iron case!
I would say be mindful and take precaution, though many would disagree and purchase a demagnetiser

* Magnetism, Have We Missed Out The Obvious? Laptop-Users Be Aware!
Upon reading the thread about Magnetism Effect from Watch-Winder "Navel Gazing - A Question for Watchmakers and Engineers..." by Harry Tan, I suddenly remembered there is a question I've always wanted to share and ask. The little experiments and photos we...
I am keeping my watches
But throwing out my lap top. LOL. Only kidding. Lucky for me I am right handed so I don't have to worry about cell phone magnetism. Thanks Kong for the great report and the bad news. Bill
thanks Kong. i spend a lot of the day using my laptop and
wearing 2 watches i am willing to accept time gain or loss although i havent actually noticed any. but does it do any damage to the watches themselves? Graham
I knew that there was a practical aspect...
to my collecting vintage IWC Ingenieurs! Thanks for the interesting post. Tony C....
Kong, useful information. Thanks
Apart from laptop, handphone also has very strong magnetic field. I haven't done any experiment. Don't know how actually it will affect the watch when you hold your handphone with the same hand. Regards Ling
Knows the source of the magnetism & avoid close proximity...
The distance between the handphone and the phone is far, so has no effect, except when ....you placed your watch side-by-side with your handphone. The strongest magnetic field is at the earpiece (the speaker)! I believe in taking precaution.... a few of o...
Doubt so...a soft iron cage also has 'weak points' like....
the date-window, the hole/s of the hands (hr, min, sec) and the crown. It depends on the strength of the magnetic source So prevention is better. Kong
Hmmm . . . some of my favorite watches are . . .
. . . the Ingenieur, Milgauss, and Railmaster, both vintage and modern . . . I thought it was primarily for aesthetic reasons, but perhaps there was a magnetic subtext as well . . . curiously, Art
Thanks, Kong, great detective work!
I'm particularly sensitive to magnetic fields, and get a headache just from using cell phones - a bona fide, wave pressure migraine just from having an active cell phone operating near my head/ears. But it is a good idea to note that EMI and RFI are relat...
Good information, Kong. From now on, i will only be...
wearing quartz watches when doing a lot of work on my laptops.
