Hermione was wrong about muggle artifacts

For quite a while now, I've held the theory that the whole 'muggle 
artifacts go haywire around Hogwarts b/c of all the magic in the 
air' belief is nothing more than superstition.  Most of my argument 
comes from logic rather than the books:

1) Obviously the problem cannot be caused by magic interfering with 
mechanical actions because otherwise no one would be able to move, 
or indeed even live anywhere with magic seeing as how the human body 
is, in itself, a machine.  Or, if you don't accept this argument 
(supposing that wizards could endure it b/c they are magical 
themsleves, at the risk of a run-on sentence however, consider 
squibs, i.e.- Filch, and there ability to endure magic), then you 
might consider the fact that the wheels that the carriages ride upon 
run smoothly.  There are other examples, but I'd rather move along.

2) It can't be a problem of eltricity being interrupted, again b/c 
of the fact that the human brain, even the non-magical squib brain, 
has no trouble relaying messages in the nervous system via 
electrical impulses.  Or again, if you counter my argument with the 
magical blood silver bullet, then consider Hermione's muggle parents 
in diagon alley (Hermione herself mentioned diagon alley as another 
hotspot for magical interference).

3) It most obviously can't be a problem concerning waves (in which 
case we would then be limited to considering things such as muggle 
cell phones and such), because if so, then people would not be able 
to see because light waves would be interrupted and distorted, nor 
would they be able to hear because sound waves would be distorted.

Now, even if you somehow find an argument to beat all of that, there 
is the simple matter of Harry's watch.  Harry's muggle watch, prior 
to its destruction in the fourth book (when Harry wore it 
underwater), worked fine, even in Hogwarts.  Now, most watches made 
today are powered electrically, as well as having moving mechanical 
parts, so, clearly, neither of those forms of energy can be 
problematic. And I can safely assume for two reasons that the watch 
is a muggle watch: 1) Harry's had it since the first book, and 2) 
Harry's purchase of a watch from a wizard shop is not mentioned 
prior to the fourth book.  Of course, one might say, Harry might've 
bought that watch in diagon alley without its mention, however, JKR 
always lists everything that Harry buys after shopping trips, and 
everything he receives for B'days and Christmas.
