What does she want? IMO, you can get all you need out of a running watch in a good ole timex ironman which you can probably find for about 30 bucks. If you are looking for fancy gadgetry, it depends on what you want ... GPS, heartrate monitor, pacing device, etc. I've seen some people running with what looks like a laptop computer attached to their arm ... it's ridiculous. I, personally, don't think a fancy watch is a good investment but I know pace / distance better off the top of my head than the average joe. You gotta figure out what you want out of the watch.
