Not sure about quartz.

Feb 04, 2008,23:02 PM

I had a bad experience with my quartz watch when I was working near some bus-bars in an electrical distribution board.  My watch ran a full one hour fast within a two hour period.  I suess the field is not as strong near a lap-top speaker or hard-disk.

* Magnetism, Have We Missed Out The Obvious? Laptop-Users Be Aware!

 By: Kong : January 26th, 2008-10:33
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

most of the time it's easily fixed

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...

 By: Kong : January 27th, 2008-10:19
The distance between the handphone and the phone is far, so has no effect, except when 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...  

Very interesting post Kong!

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

Not so sure about that.

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...
