Number 1139 seems to confirm it.By golly, I think you've got it.
I had heard this theory in regard to pocket watches, but never wristwatches -- but it makes perfect sense. This would explain why the watches are export models (English writing on the dials, date wheels, and back covers), and also why there is a misspelling on the inscription of one of mine. I just never put two and two together.
