Colonial U.S.A. is a private label in Seth Thomas 18-size Model 10, Model 11, Model 12, and Model 13. Despite the diversity of pocket watch movements with “Colonial” inscribed on the movement or dial there is no known evidence to support any account of this Colonial U.S.A. private label pocket watch’s historical origins.
