Not sure about quartz.
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.

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
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...
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...
