rerunvpHamilton a very historic watch manufacturer with a rich American history as well as some historic innovations in watchmaking. It was bought in 1974 by what is now the Swatch Group. In 2003, Hamilton (HQ & manufacturing) were moved in total to Switzerland. Hamilton movements are Swiss, designed in conjunction with ETA, in Switzerland with Swiss parts. Hamilton watches are Swiss Made, through and through, but have maintained the American history and spirit in their designs. To say otherwise is patently untrue.
