I was able to rename my USB watch flash drive to "Watch" in OS X 10.3

Oooh, that is wrong. You are not changing the volume label but rather 
moving/renaming the *mount point*. Which is bad.
And in any case you can't do it while it is mounted.

Well, it depends of the filesystem, really. If it is Fat/Fat32, you 
would see the resource fork files, which is perfectly normal.
A drive knows its name by the filesystem label. How is your drive formatted?
