Best Rolex to pair with a black dial smooth bezel 36mm Datejust on a jubilee?

[ReclinerTimer]

Hi all!
So the watch I wear most is my 36mm smooth bezel black dial Datejust on a jubilee bracelet. It is my only Rolex and I love it very much. But I'm dreaming about one day in the future when I decide to get it a companion. It's a very broad question I know, but in your opinion which Rolex would pair best with it? It can be vintage or modern, but keep the case size at 40mm or less because I have a small wrist. Just trying to begin the process of opening my eyes to what could be my next piece and would like to hear some recommendations from the forum.

Thats a dressier watch so I'd go with something from the sports line.

A Submariner or GMT II depending on your use preference would go great with it. A white Explorer II would be a great contrast as well.
