Abstract
A method for manufacturing at least two mechanical parts to be arranged in a timepiece mechanism including magnetised functional areas having antagonistic polarities, the parts being arranged in a timepiece mechanism to cooperate with each other in relative displacement, the method including a step of constructing a blank of each of the two parts including at least one functional area from which the parts are able to cooperate with each other and a step of obtaining each of the parts including a sub-step of transforming said at least one functional area of the blank of each of these parts into a magnetised functional area from which emanates a magnetic field, at least one feature of which is configured so that this magnetic field participates in achieving a separation of the magnetised functional areas of the two parts when they are in a stop position in the mechanism.
