Cosmopolitan is a private label in Seth Thomas 18-size Model 5. The movement is marked “The Accurate Timer” - “Cosmopolitan Watch Co. - U.S.A.” The dial is signed Morris Feinberg - Ironwood, Mich. 

Morris Feinberg (1879-1929) immigrated to the United States from Russia in 1893. He was a watchmaker and jeweler with a shop located at 224 Suffolk Street in Ironwood Michigan. His business partner was Raphael Sloan. The shop at 224 Suffolk Street is in the first building on the right-hand side of the 1910 photograph below. A 1904 City Directory reports that his shop was also located at 112 Ellison Street in Ironwood. There is an excellent story by Steven Heifetz on Page 12 of the Daily Globe History Project, March 20, 2018 edition describing the experience of Morris Feinberg and other 1890’s Eastern European immigrants settling in Ironwood Michigan. 

Roy Ehrhardt’s “Identification and Price Guide” reports that the Cosmopolitan Watch Co. movements were also produced by Illinois Watch Company.
