It is her wish as a 17 year old. Yes, we look down upon the brand as an inexpensive Japanese Quartz movement inside a brand. The thing is her current wish is shaped by a growing desire to have the brand. Kors has done a good job then.
Just my 2¢, maybe get the Kors and get a nice looking pre-owned Rolex that's a tad more conservative (maybe an Oyster P.) and see what happens in 6 months...
