An assembly element having two series of elastic structures and a timepiece fitted with the same are provided to optimize a resistance against a linear acceleration along a rotation axis by arranging the elastic structure between an upper layer and a bottom layer. An assembly element includes at least one support surface(36) and a hole(32). Arbors(26) are radially fixed on the support surface, so that the assembly element(18) is fixed on the arbor. The hole is provided for an axial insertion of the arbor. An inner wall(33) of the hole includes an elastic structure(34), which is etched on a plate. The assembly element is formed in the plate which is made of a brittle material, such as silicon, for a timepiece. The assembly element includes first and second series(S1,S2) of the elastic structures. The first series of elastic structures are etched in an upper silicon layer(39) of the plate. The second series of elastic structures are etched in a bottom silicon layer(41) of the plate.
