Serial Number 1129522 was reported as inaccurate.

Note: Is a model 4 and it is pendant set and 15 jewel. I
am positive that I have the serial number correct
and I showed it to a few watch makers who said
that it is very strange but is in fact this grade.
It is marked 15 Jewel and I also took the dial off
to confirm. It is a private label for Jacob ramser
of Rock Island Illinois. If there was a way for me
to send you pictures of it I will my email is
