The invention relates to a method for manufacturing an epilame mechanical part (2) comprising a substrate (4) made of a first material, the method comprising at least:

a step (10) of depositing an epilame product (6) consisting of a second material on the substrate (4), said deposition being carried out in the form of a projection onto the substrate (4) of at least one collimated or localised beam (12; 12A, 12B) of material containing the epilame product (6); and

a step (11) of treating the second material to ensure the cohesion of the components on the substrate (4).

A mechanical connection device, in particular a mechanical connection device for a timepiece or a mechanical transmission device for a timepiece, includes a first part having a first area with at least a first micro-cavity; and a second part having a second area with at least a second micro-cavity, the first and second areas being in contact with one another in a mechanical connection configuration.
