History

In 1879, Dietrich Gruen, a watchmaker living in Columbus, OH founded a Co named Gruen & Savage. At the turn of the 20th century, Gruen only used Swiss movement even though the production of the case and finishing were done in the US. Gruen made is own manual caliber called “Very thin”. In 1908, Gruen introduced watches for women’s and then a solid gold movement to celebrate its 50th anniversary. In the 1930’s, Gruen and Rolex used the same caliber in the “Duo-dial” and the “Prince”.

The mythical curvex model was introduced in 1935 and then the “Curvametric” in 1948 and “Autowind” in 1958.
