you have stretched the time period too far, KMII.
Starting latest in the mid 90s, watch designs have gone back to classic designs that still today look fresh and brands revived mechanical movements and developed in-house calibers.
When I see Lange 1 being submitted, then this is clearly no longer the dark age
So let's see if we can find some real 80s designs...
Here is a GP from the 80s that is so typical why they are considered the dark period and are neglected by collectors today....
You have here a full platinum case and bracelet of the highest manufacturing quality which resulted in an exorbitant price
Combined with a (at best) quirky design with milli meter paper design dial
And housing a mass-production, uninteresting quartz movement.
That combination is just killing it.
(yes, this is not my watch!)
Another 80s/early 90s design example are the mixed steel/gold cases.
Here you have a more classic case design, still 80s, but more classic, but the highly polished yellow gold bezel really sticks out.
Mechanical (ETA) Chronograph movement with loupe date.
Another example from times gone.
