Abstract: A Dewar device for mechanical and/or functional components of a watch, this device including a wristlet; a housing including a chamber wherein a case of the watch is capable of being disposed in such a way that a glass of this case is arranged facing a glass of a set of elements of the housing defining this chamber; at least one fastening device fastening this watch case in this chamber of the housing while maintaining it distant from this set of elements, and a device for actuating at least one control element of this watch by the movement in translation of an external parts element of the housing in the direction of a back of this housing.

Abstract: A shock-absorber and/or vibration-absorber device is proposed, comprising at least one flexible element able to deform under the effect of a stress; said device being remarkable in that it includes at least one so-called dissipative layer made from a material having a shear modulus lower than the shear modulus of the flexible element, a shock-absorbing factor greater than the shock-absorbing factor of said flexible element, and at least partially secured to said flexible element such that a flexion of the flexible element, under the effect of a stress, provides shearing of the dissipative layer making it possible to dissipate at least part of the energy from said stress. A method for manufacturing said shock-absorber device is also disclosed.
