232, 249, 448, 449 all of which are 47mm Radiomirs, my choice would lean towards the PAM210.
It has few advantages over the bigger models. It's a 45mm (no monster to be strapped to the wrist unless YOU choose it). It has a quintessential 3-6-9-12 Panerai dial, it can be found at reasonable prices and gives you the chance to decide if 45mm does it for you or you need a 47mm. You can find some NOS or LINB pretty easily. You NEED the bigger version? PAM232....
