Buy new 380 or per owned 210 or 183 ??

[Jcru2001]

I'm searching for my first Panerai, which will be a second watch, not a daily wear. I'm focused on the radiomir due to size and slimmer silhouette. That said, I don't want to go full out and drop $5k or more, but would like to have a piece that will retain value in the future. And I understand I'm talking about entry level Pam's here, which will probably not retain all value.

So a brand new 380, showing the logo, or a per owned 210 or 183??

Thanks in advance.
