Congratulations on a story extremely well-told
Condolences, though, on the contents of the story!
One question, though: do my eyes deceive me, or is the screw not fully seated in the original pictures? If it wasn't, that might explain how it came the rest of the way out when you wound it--you made the barrel turn but the screw, not being tightened, came undone with each turn of the barrel?
If that's right, though, it's inexcusable--almost unbelievable--that the watchmakers who checked the watch in July could have missed it.
