Method for coating micromechanical components of a micromechanical system, in particular a watch movement, comprising: - providing a substrate component to be coated; - providing said component with a diamond coating; wherein said diamond coating conductivity is increased in order to reduce dust attraction by the coated component when used in said micromechanical system. Corresponding microchemical components and systems are also provided. L'invention porte sur un procédé pour le revêtement de composants micromécaniques d'un système micromécanique, en particulier d'un mouvement de montre, comprenant : l'obtention d'un composant substrat devant être revêtu; l'application sur ledit composant d'un revêtement de diamant; la conductivité dudit revêtement de diamant étant accrue afin de réduire l'attraction de poussière par le composant revêtu lorsqu'il est utilisé dans ledit système micromécanique. L'invention porte également sur des composants et systèmes micromécaniques correspondants.
