Humm...........Interesting and it turns out I have just such a specimen. I received this 6002 from May of 76' sometime ago. It had taken a hard blow to the crystal + case back shattering the crystal and mangling the hands. I wish I had take a before shot with the bent and tangled hands but I was in a hurry to see if it still ran so I straightened the hands a bit, popped in a used crystal, put on a temperary case back so the rotor could turn and gave it a few shakes and it was up and running. Simply amazing after seeing the blow it had sustained. I was under the impression that it had the wrong inner bezel but now I have to wonder. I had robbed the crown + stem for another watch and it's remained in my project box.
