Abstract

A shock absorber device for a movement (4, 104, 204) of a watch adapted to be housed between a case middle (1, 101, 201, 301, 401) of a watch case and said movement (4, 104, 204), the device comprising a casing ring (5, 105, 205, 305, 405) for said movement and a plurality of elastic elements (16, 116, 216, 316, 416) distributed over the perimeter of said casing ring and arranged between said casing ring (5, 105, 205, 305, 405) and the case middle (1, 101, 201, 301, 401) of the watch case, wherein said elastic elements are configured as double leaf spring elements (12a, 12b, 112a, 112b, 212a, 212b) having a central root portion (13, 113, 213, 313) fixedly secured to said middle of the watch case and two free tip portions (14a, 14b, 114a, 114b, 214a, 214b) resting on said casing ring. In particular, said leaves are arranged in cantilever position carrying loads from said free tips to said fixedly secured root portion. In an embodiment, said double leaf spring elements are discrete spaced apart workpieces (216, 316) whose central portions (213, 313) are shaped to be fitted into conjugated receiving portions of the wall of the middle of the watch case. In other embodiments, said double leaf spring elements (16, 116, 416) are carried inwards by a supporting ring (8, 108, 408) fitted within the middle of the watch case.
