Abstract
PURPOSE: To simplify the fabrication of a winding crown of a wrist watch in response to a variety of models of the watch by constructing the crown by two elements, separately mounting the elements at a crown stem holder to thereby simplify the work for securing the crown to the holder.
CONSTITUTION: While turning a crown body 3 held via packings 5 at a crown stem holder 4 assembled in a movement, it is so mounted as to eliminate the gap S between the crown body 3 and a drum 1. The crown is mounted while turning the crown head 6 at the holder 4. Then, the crown head 6 is fixed by a jig 10, the portion formed with the crown body 3a and knurling tool 3c is held by hand, the crown 3 is turned in loose direction to thereby fix the three members. There are set gaps S1 and S2 between the crown head 6 and the holder 4, and between the crown head 6 and the crown body 3, respectively to respond to some degree to the variation of the thickness 1a of the drum 1.
