·Very early watches produced in the U S had vitreous enamel dials that were sourced largely from England. The U S makers hadn’t learned how to do that type of work. I’ve forgotten which watch company it was, sent a fellow to England to learn how to produce enamel dials.
Henri Focuey, who worked for the American Watch Company, introduced glass enamel dials to the US. I believe he had learned it in Switzerland before immigrating to the US. I don't know for certain what year, but by the early 1880s glass enamel dials were being used by Waltham and Elgin.
Aaron Dennison is notable for being the first person to believe that watches could be mass produced. With the American Watch Company he pioneered the use of mechanization and interchangeable parts where possible in building his watches.
