New to Panerai with a few questions

[donas]

I have gotten the itch to try out Panerai again; I bought a Radiomir several years ago and had immediate buyers remorse. I've done my best to search out some answers/info but would like the "experts" here to solidify my searches.

I don't really care for the "rounder" looking Luminor case and crystal, so this seems like the 1950 style is out -right? Do some 1950s have flat crystals? The manual wind cases are going to be slightly thinner than automatic?

I think I am leaning towards the PAM 510. I can't find too many recent reviews or posts on this movement; most of what I see are from a couple years ago when the "haven't had the test of time" posts were common. What is the general consensus of this movement vs the eta in the PAM 111?

I am open to suggestions from those who are far more versed than I. I think I would prefer the sandwich dial, small seconds, clear case back, water resistant to 300m. (The clear case back on the 510 is a little boring which is one complaint I have with that model).

Thanks for the help
