Well, I have an even harder one to satisfy with the perfect watch, my daughter. She is 23 and one of the first requirements is quartz. She is not likely to wear the same watch everyday and does not want to have to do anything to make it ready for use.
For ROTC and sports (Cycling, shooting, stuff like that) she likes the Casio G-Shock line; so, all I am looking at is dress watches. In that regard, her description of what she wants is, "Traditional feminine." A watch suitable for concerts, art shows, and wandering around museums.
She has nixed (said no to) several including the ladies date-just. Her complaint is that they look like, "smashed-down mens' watches." I actually got her the square Cartier at the beginning of this thread.
She is going to try it and see how she feels about it. Her complaint is that it looks, "too masculine." She wants metal, round form, dainty, no excessive bling (other than skeletonized, which she likes), no fake diamonds or other non-functional ornamentation, and very feminine.
I know, this is an almost impossible order to fill. At some point she and I are going to go to GZ and hit some of the shops so that she can take part in the selection.
