Deafboy, I just picked up the identical watch. Same dial, same CK 2907/1 reference back, same mis-spelling, 15 million serial, same symmetrical clutch bridge. I can confirm that some these early 2907s have the mis-spelling, as there is nothing on my watch telling me that it is not original.
However, I need help! I cannot find info anywhere on which end links and bracelet fit this case. I even called Otto Frei and they couldn't tell me, as they no longer have parts for this case.
