First, WOW!!!

Your daughter sounds so very impressive. You must be a proud papa!!

Second, I'll agree with you that your daughter should be actively involved in the selection of the proper watch.

I've found that my young adult kids know much better than me what they want and what they don't want. My son would very much rather have nothing than something he doesn't want.

Talk with her about it. It sounds like this is NOT the time/place for surprises.
