Hi Horseman,
First of all, welcome to the PuristSPro and you are in the right place of Panerai lovers.
I first starts my Panerai experience with 005....why??? Because I love the "OP-logo" and manual winding is my preference for Panerai. Why no Pam 000......???.....only because I love to see some movement on the dial.
It's not quite right when comparing the luminor with the radiomir as they have different looks, especially the case. Frankly speaking, the Radiomirs look more dressy than the Luminors. Therefore, if you are looking for something "dressier"...the Radiomir will be your right choices.
Regarding your question on the manual winding, I don't feel any annoyance or inconvenience of winding my watch. If you are looking for something that have power reserve indicator (with manual winding system), I would suggest you too take a look at PAM190....
It is one of my favorite Radiomir...45mm, manual winding, gold hands with seconds dial, 8-days power reserve, crystal caseback...
It can goes well with the gator strap...
Hope this help you more or less.
Cheers
Krieng
