Reccs on Vintage Rolex as a Gift, Please.

[GoneWiththePups]

First of all, thanks to everyone who contributes to this forum! It's been incredibly helpful!

I was married in Oct. 1989. This year I will celebrate my 25th wedding anniversary and I want to surprise my husband with a 1989 Rolex. Neither of us are collectors, so it's not like we/he's had his eye on a particular model. To surprise him, I'll have to make the selection all on my own.

If you had to buy only one men's watch as a gift (as I've described above) in the $3k-$6k range, what model would you search for/get? What model would you stay away from? Why?

I have a lot of time to research but hearing from experts would be a great jump start!

Thanks!
