He can't, because the 616 is a 47mm Luminor 1950s Submersible, while the PAM700 is a 49mm Luminor 1950s non-submersible. The mid case would be too small, and then you would not have the bezel to put on top. The only carbotech cases we have with non-submersible bezels are 44mm (either the PAM661 or the fantasy carbotech models that were released earlier like the PAM441). Then you would need to get a suitable dial, which would be custom since there isn't an existing dial with very blue lume plus the unique subdial @9. Plus the etched LUMINOR PANERAI and LAB-ID on the crystal. It would take a bit of custom (and probably expensive) work. So I'd probably just wait for the factories to make the watch, it will probably drop within the next 3 months.
