As the title states, I'm starting my search for a 1955 IWC Cal 89.

I'm leaning towards the less ornate or fancy lugs, I would potentially consider the right one with the "shark tooth" lugs.

Open to all case metals in good+ condition, my preference would be steel, rose gold, yellow gold, in that order.

Prefer the dials that have the 12-3-6-9 Arabic numerals, but am open to finding the "right" overall watch.

In general, I'm just seeking a very good or better condition cal 89 in honest, original condition, but it has to be from 1955. I realize most that have them here are holding them, but I'm putting this out into the universe. Thanks in advance for any tips, leads, or offerings you may have!
