Just curious as to whether anyone has ever had trouble with the magnets in their iPad smart cover magnetizing their mechanical watches. I'm always paranoid about holding my iPad in my left hand when the cover is folded back.

I haven had any trouble as of yet, but I value the experience of others in such matters.

I spend A LOT of time with my iPad and never had any issues, but then I'm usually wearing a Ball which is a little more anti-magnetic than usual

Watches are designed to comply with the ISO 764 standard which requires them to resist a magnetic field up to 4.800 A/m (Ampere/meter).

Here are some examples of the magnetism emitted at close contact:

- Mobile phone speaker = 22,400 A/m
- Electric shavers = 10,400 A/m
- Magnetic furniture latches = 64,000 A/m
- Positional magnets = 144,000 A/m
- Laptop & PC speakers = 16,000 A/m
- TV set = 800 A/m

You can figure it out from here.

That's good info. By that, I'm lucky my watches work at all though! I'm vey careful not to put my watches in direct contact with my devices. I just wondered about when I'm holding the iPad. That puts my watch 2 or 3 inches away from some fairly strong magnets. I've never noticed any problems though.
