So after restoring a few watches, my friend came to me with an emergency...damaged a fairly old panerai ( A series), and the AD suggested a new case.
We know that the factory would just put a current series case which would devalue the watch a lot so he let me take a crack at it!
Basically bezel, side of case, lugs were scratched to heck, and there was a sizable dent! Crystal was also scraped! Ended up re-machining a whole side, re-machine part of the bezel, and a lot of polishing with wet sand paper / clay / dremel / diamond paste
Wish i took more pictures "before," but after the watch looks brand new now! I didn't want to unscrew anything so it was just a lot of masking. I'm glad the steel is of high quality to accept all that beating and come out ok. About 6 hours of work but at least I know I can do it now with a collectible lol.
