What's the aging like for watch crystals?

What type of cut to watch crystals use?  Are there any generalizations about 

I don't remember any tales of watches changing from good to bad after a 
couple of years.  Surely there are enough geeks who keep an eye on the 
performance of their watches that somebody would have noticed.  Or maybe they 
setup the initial calibration so it gets better as it ages for the first 

These are my opinions, not necessarily my employer's.  I hate spam.
