Abstract
A timepiece assembly including a first component and a second component assembled under stress, wherein at least one part of the surface of the assembly is coated with a protective layer intended to cover defects such as cracks or incipient cracks after assembly. It also relates to the method for manufacturing this assembly.
Claims15
A method for manufacturing a timepiece assembly, the method comprising, successively:
- assembling an inertia screw to a balance, the balance comprising a resilient arm delimiting a slot configured to receive the inertia screw, under mechanical stress by elastic deformation of the resilient arm and insertion of the inertia screw into the slot, to obtain a component assembly;
- and
- depositing, under stress on the resilient arm, a protective layer on at least one part of a surface of a stressed area of the component assembly configured for the timepiece assembly,
- wherein the timepiece assembly comprises the balance comprising the resilient arm delimiting the slot;
- and the inertia screw assembled under mechanical stress, and
- wherein the slot is configured to receive the inertia screw.
