Why oh why bother doing this. I can't imagine that someone can build these things cheaply enough to warrant the trouble of the tiny return you could possible get from selling them to someone who doesn't know better. You are almost better off printing some cute dial with a cartoon character and selling the resulting piece as something cute but original targeted at kids. at least then you'd be selling the same crappy watch as something people might actually want to spend money on (even if not much money).
