Abstract: A method for manufacturing at least a part of a timepiece is disclosed. The method comprises a first step of assembling flat layers together to from a substantially flat multilayer structure, Wherein at least a first layer of said layers is designed to form one flexible blade in the timepiece. Then, the multilayer structure is deployed in a direction substantially normal to the flat layers. Then at least one mass is fixed to the flexible blade, the mass being more rigid than the flexible blade.

Abstract: A method for manufacturing a mechanism comprises the steps of: i) assembling flat layers together to form a substantially flat multilayer structure; ii) deploying the multilayer structure in a direction substantially normal to the flat layers. At least a first layer of said layers forms a flexible blade in the mechanism. The blade is fixed, in the mechanism, to a mass. The mass is more rigid than the blade. The blade is fixed to the mass in a step subsequent to step ii). This method can in particular be used to manufacture all or part of a mechanism such as a timepiece movement.
