New 31mm Watch Purchase Suggestions

[Waterworld000]

Hello,

I am looking to purchase a 31mm watch as a gift for my Girl Friend. I will list some of the key items I know she likes. My goal is to find a piece that she will like, but also retain the most value down the road over the next few years out of the options below. If you could suggest models that would be better for this or even suggest models to stay away from (hold value poorly) that would be great.

-31mm
-No Jubilee bracelet
-No fluted bezel
-No diamonds on bezel (face ok, but not necessary)
-White or Mother of Pearl face (preferred)
-No Gold on watch, unless it is white
-No used or pre-owned

Budget 6-7k but would push to 10k if necessary

Thanks
