1. 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.
