Warning...all iPad Users!

One of the assets of RWG is the ability to learn from the mistakes of others.  Therefore...

 

Do not set your watch on your iPad if you have a Smart Case.  It has a pretty strong magnet in it.  I found out the hard way.

Thanks for the info. You know there have been a lot if folks on the rep and gen forums with magnetized watches, I wonder how many are due to IPad case magnets? I have one, and I use it a lot, my watch is pretty close to the case for long periods of time. Any idea as to what is a safe distance, or do you have to lay your watch directly on the magnet ?

Well the magnetic field falls off by the distance squared so there is a very fine line between too close and fine and the line is likely very close to the magnet.

I would think that in the case of an iPad, contact would be too close, but a couple of inches would be safety.  What I did was worse.  I was finishing up a movement to case it in my 1680 and sat the movement on the case, on top of the magnet.  When I put it on the Timegrapher a nearly perfect movement just went "haywire."  Everything was wrong.  Amplitude went to 120 and the lines were running up at a 60% angle...150+ minutes fast.  Lots of noise outside of the beat lines.

 

Luckily, I do have a degaussing coil, so I ran the whole watch through it and that apparently has realigned the molecules in the metal.  It is still not as good on the analyzer as before, but I think that the rest of the magnetism will subside...maybe... 

 

JUST DON'T DO THAT!
