Abstract

825,682. Watches. PIQUEREZ, E. July 5, 1957 [Aug. 13, 1956], No. 21314/57. Addition to 779,034. Class 139 In a modification of the invention disclosed in the parent Specification the crown 6, Fig. 1, is made of a synthetic plastic material, is cast on a metal core 7 and has a metal cover 11. The core 7 extends into a tube 4 carried by the caseband 1 and a coil spring 10 urges a sleeve part 8 of the crown against the outside surface of the tube 4. In another example, Fig. 2, the crown has a sleeve part 14 which extends directly into an opening in the caseband and is urged against the wall of said opening by a coil spring 15.
