Abstract

A crown assembly for use on wrist watches having a crown provided with an axial blind bore. A stem has an end portion received in the blind bore and is fixedly coupled thereto by coupling means having an interference fit with the blind bore. The arrangement permits the crown assembly to be manufactured with the crown and stem made independently and of different materials.
