The invention relates to a method of bonding watch components, comprising applying an adhesive to a first (12, 14) and / or a second (16) watch component to be bonded to one another and forming a tie coat on at least one of the first and second components to be bonded by spraying a primer composition into a localized bonding zone, followed by solidification of the primer composition. The formation of the tie layer is carried out before the application of the adhesive if the adhesive is applied to the same component as the tie layer.
