From the description you gave of her I do not think these watches suit the profile. That set looks more appropriate for husband and wife kind of deal, you know "his and hers". The watch is very classy and she looks like a classy girl. You should get her a funky watch.
You should ask her out, she is very beautyfull and if you end up marrying her that set would be a nice 5 year marriage anniversary gift.
Good luck.
