I also can attest to the fact that Panerai sure repolishes and rebrushes each individual link in the metal bracelet from my own personal experience when I sent in my ex-PAM52 chrono w/ bracelet in for service. The bracelet had tons of scratches before; and when I got it back from service, it looked absolutely brand new. Must take forever to unscrew and refinish each link and then assemble all pieces back together.
Thanks for the story!
Cheers,
Anthony
