Picked this up today and it's kind of a cool little timepiece. It is hallmarked 0935 Movado Factories Swiss Made Patent Fab Suisse 428. Fully opened it is 70mm and closed it is 48mmx33mm. The crown is on the top and is very ornate and winds the movement when you open and close the case. I'm waiting on the pictures of the movement so I don't have that info yet. The dial is in very good shape with newly lumed hands that were blue but have darkened over time.
I have seen these with leather over the case and this one may have once had that as well. I like this little thing so much I'm keeping my eyes open for an Ermeto with a moon phase.
Any additional info is welcomed.
