Description (Brief)
Pauline Hortense Gontard, of Cortébert, Switzerland, submitted this brass model with her patent application for an improvement in the winding mechanism in a stem winding watch or keyless watch. By the time, she applied for the patent in the United States in 1879, American watchmakers were mass producing watches and competing with European watch makers.
Stem winding watches were invented by a French clock maker in 1842 and patented in Europe in 1845. Before this time a key was necessary to wind a watch mechanism.
