@SouthCoast... there's the perennial question. My estimation of what will become collectible is, "is it rare?" and "is there a coolness factor?" and "does it serve a segment of society that others will eventually want to emulate?"
For Doxa, the answers were, and continue to be, "yes", "yes" and "yes". Same with vintage Rolex.
Now think of any Rolex made since about ca. 1985. Ask the same questions and you get "no", "yes" and "no".
Are your links rare AND cool AND desireable? No, yes, and yes.
If they only made 100 each of the Zinex, then I think you'd almost have something. But for the most part they're hommage to existing genuine cool vintage pieces... so I doubt they'll go where the gens have gone.
Just my $.02
