Lemania dress tonneau?

[chipsotoole999]

Just picked this up for a snip on eBay. it came from a house clearance in the old DDR. It also came with a period jewellers box and guarantee slip from 1959. On it , it is referred to as: 9104/Pa automatic...Can't find out a thing about it, not even a single Lemania Tonneau pic of this type on google images..... It's hardly been worn, perhaps it was a Sunday best watch. I've taken an instant liking to it and it's going in my Lemania collection! I took the top of to remove a couple of specks from the dial and polish the glass, but didn't really want to pop the back off .Can anyone give me any pointers about this ref, this model, or a guess as to the calibre? I'm getting the feeling it's a bit of a rare bird...

Swiss Made for an old watch on the dial can be suspect but I have never seen a Cushion Lemania like that.... anyone else..?
