Dear all,
I own the movement in pictures below, but I know almost nothing about it.
It seems that the case was melted - it was probably made of gold, otherwise I don't see a good reason to strip off the movement.
Anyway, I searched over the internet to find a movement like this one but without any good result.
Maybe, with your help, I shall have more pieces of information about this tiny piece of history.
Thank you in advance.
