Looks like a PAM 572. SF Factory JUST released a new version that features a clone p.4000 movement that has some serious flaws such as the misspelled thirty-one jewels engraving on the movement that actually says "Thietry-One Jewels". Really cool in-house movement from Panerai with the micro rotor though
There are alot of nice Radiomirs that are first class reps with some bordering super rep status. My recommendation would be to figure out what case size you're interested in (42mm, 45mm, 47mm, etc.). Then use ALE's PAM guide and do your research on the accuracy and differences between factories.
