| Description | Hamilton Watch Company (Lancaster, PA, founded 1892) began sourcing Swiss-made movements in the 1950s–1960s to supplement domestic production; Certina (Kurth Frères SA, Grenchen) supplied Hamilton automatic calibres including the 28.45. Hamilton fully ceased Lancaster manufacturing in 1969, shifting all production to its Swiss subsidiary Buren. |
