·Maybe it's genuine then?..
I believe so, i don't see any signs of franken or recasing. The movement matches the case perfectly and the case is equal in the three examples.
Maybe it was a showcase watch (it was very unusual the use of a crystal back in the era...), with the intention to prove that the microtor movement (a novelty back then) was an automatic movement so efficient that even could be used in a pocket watch (just like the Eterna did with the Eterna Golfer)
But i would love to ear other opinions...
