Watch movement mounting structure

A watch movement mounting structure for fixing a watch movement having an annular flange in a watch case having a case body including a radially extending annular shoulder and a radially inwardly extending annular projection contiguous with the annular shoulder, comprising:

• a flexible annular support member including an annular wall adapted to rest on the annular shoulder of said body, a plurality of circumferentially spaced, inwardly directed flange segments each of which extends upwardly of the annular wall to retain the watch movement, and a plurality of circumferentially spaced, outwardly directed flange segments each of which extends downwardly of the annular wall and adapted to engage the annular projection of the case body, whereby said watch movement is fixed in place in said case body and the axial displacement of the watch movement is prevented;
• each of said plurality of circumferentially spaced, inwardly directed flange segments including a radially inwardly facing recess adapted to engage the annular flange of said watch movement, and a hook portion formed adjacent said recess and engaging an upper surface of the annular flange of said watch movement;
• and
• each of said plurality of circumferentially spaced, outwardly directed flange segments including a radially outwardly facing recess adapted to engage the annular projection of said case body, and a hook portion formed adjacent said recess and engaging a lower surface of said annular projection.
