STRUCTURE FOR POSITIONING A WATCH STEM

摘要

A watch stem having annular grooves thereon is precisely positioned by means of a leaf spring held at one end to a base plate. Proximate the other end of the leaf spring a tab bent toward the base plate seats in one of the annular grooves. Second and third tabs span the watch stem in a diametral direction and prevent motion of the watch stem in a direction transverse to the axis. A fourth tab is positioned by the walls of a notch in a member fastened to the base plate. The leaf spring is thereby prevented from moving in a direction parallel to the axis of the stem.
