^ I think the faux patina can be alright if done very subtly.
I asked about the 512 as I'm not entirely sure how I feel about it.
On one hand, I think the 1940 case is a rather successful combo of the 30's Radiomir and the 50's Luminor. The slimness and reduced size looks like they'll make it easy to wear. And I like the crown and how it (at least in pics) looks flatter than the 399 one.
OTOH, I can see the argument for the wire lugs and onion crown if you're going Radiomir. And I'm wondering if the slimness actually makes the 512 too dainty for a PAM
As for reduced sizes on PAMs, I don't think it works with Luminors but I like the Radiomir 337 - though I think I might have preferred it as a base model.
Actually, I think a 42mm base Radiomir could be a perfect partner for a Luminor Marina. Brown dial and cream coloured luminova, please
