Do you remember what FreeBSD version you tried this on? I use watch under FreeBSD 4.9 without any problems, and can kill it without resulting in the machine rebooting. It would be nice if this could work on -CURRENT, but I don't know how to go about debugging something where the machine reboots (not even the kernel panics). Any hints on how to do this?
