Case Serial No.:
I believe this to be the Maxim. The only ad we have coincides with the watch.
There's an addtional serial number stamped on the back of the case, which is pretty unusual for the year. It shows: 221807, and you can see it looks like it was stamped after the fact?
It's pretty unusual anyway.
White gold case with etching down the bezel, gold numbers.
The advertisement is from a 1933 newspaper ad.
