What is THE timeless classic/quintessential Nautilus?

[ars1g09]

Have been thinking about this as I am considering trimming my collection (pic below). From the perspective of history, heritage, retaining the original design DNA, future classic potential - what would be the single best Nautilus most likely to become a timeless classic?

For what it's worth, in my opinion the 5712 is probably the strongest contender - one of the first modern Nautiluses released, complication keeps things interesting, retains the intended slim profile, incredible subtle blue (not a fan of the newer more striking blues e.g. in the 5740), and overall to me oozes the right mix between history and modernity.

Would appreciate everyone's point of view on their choices!

The contenders are the below though i'm sure i don't need to repeat it for everyone here:
5740
5990
5980
5726
5712
5711
