The only thing I know of, apart from clocks, that you should not run on the wrong frequency are oldfashioned mechanical shavers.
There are lots of consumer products sold in North America that specify 60 Hz only, and in which the transformers will hum and overheat if run on 50 Hz. I have always designed with transformers that will accept 47-63 Hz, but many competitors do not. As more and more items move to switching power supplies, this will be less of an issue (of course, in many applications the switching supplies themselves will create new issues...).
