The only photos of the movement that I took unfortunately did not include the entire (or even the beginning of) the serial number. Oh well. I need my watchmaker to open it with his vise.
But here is the case back.
Edit:
I do have a 7-year-old photo I saved, originally from the seller from whom I bought this. The SN is 16,170,XXX, so that dates it to the 1958-60 range I think, probably OK for a 1961-cased watch?
