Some more info on magnetized watches

From time to time my watches can get magnetized. I found the source - it is none other than my laptop computer. There is an easy way to find out if you have the same 'danger' lurking in your office. Take a simple magnetic compass and move it around your laptop. If the needle gets pulled in the direction of the computer, then you know that is a likely source. Pretty sure that it is the hard drive causing the magnetic force, as it spins away at thousands of revolutions per minute.

When I first started with mechanical watches a couple of years ago I had problems with watches getting continually magnetized. Some brands/models are more susceptible than others. In fact, I churned through a few watches learning about this (one of which I still miss - a JLC Amvox!). I have even thought about getting my own demagnetizer - but my current (small) collection doesn't get affected too frequently.

I was told by my AD that an alternative way of - by error - getting your watch magnetized was the new kitchen stoves, where heating is done by induction. Technically these stoves work by magnetizing the pan, and if your watch comes to close, it will be af...

Thanks...

Indeed, some are more susceptible to it than others. My other watches don't seem to be bothered by it. Will keep away just the same! : )
