Now THAT'S the kind of answer I was asking about! Thank you!! It's not out there, so that's that and a little project of mine goes by the wayside. No big deal really. Case closed (no pun intended).

It's not that hard...

using diameter of the movement as a proxy for the dial size:

Omega 321: Dm= 27.0mm, Do= 27.5mm

Omega 861: Dm= 27.0mm

for the smaller automatic cousins:

7750: Dm= 30.0mm, Do= 30.4mm

ETA 2892: Dm= 28.0mm, Do= 28.4mm

I was going to look all this up and post it, but I don't think I'll bother...
