This is an Illinois Watch Co 18 size, 17 jewels, grade 65-E, with Ball regulator modification. It's lever-set, with a two-tone finish. It is also a private label "H.M. Jacobson & Son, Philadelphia", made about 1903.
Top it all off with a display back "salesman's" case!





The two tone finish is quite interesting. I wonder how they did it.
ReplyDeleteGood question, I don't know...
