L'invention concerne encore une pièce d'horlogerie comportant au moins un tel mouvement et/ou au moins un tel oscillateur, et/ou au moins un tel composant.The invention also relates to a timepiece comprising at least one such movement and / or at least one such oscillator, and / or at least one such component.
L'invention concerne le domaine des composants et mobiles d'horlogerie, et plus particulièrement la réalisation de mobiles que comportent des oscillateurs ou des mouvements d'horlogerie.The invention relates to the field of watch components and moving parts, and more particularly the production of moving parts that include oscillators or clock movements.
La confection de mobiles d'horlogerie amagnétiques, n'est pas traditionnelle. Or il existe un besoin dans différents types de mouvements qui font appel aux lois du magnétisme, en particulier pour réduire ou supprimer les frottements, notamment dans les oscillateurs où on cherche à éliminer les arrêtoirs traditionnels de type ancre, qui altèrent fortement la réserve de marche.

En somme, le choix d'un matériau précieux, qui peut être titrable, pour la réalisation d'un arbre de mobile horloger, va à l'encontre des préjugés relatifs à l'usure rapide des alliages précieux. Le choix d'un alliage comportant au moins de l'argent et du palladium, parmi ceux décrits ci-dessus, apporte une réponse étonnante à la problématique d'usure, ces alliages s'usant très peu dans des conditions normales d'utilisation, tout en étant amagnétiques comme souhaité.In short, the choice of a precious material, which can be titratable, for the production of a watchmaker's mobile shaft, goes against the prejudices relating to the rapid wear of precious alloys.

Naturellement, même si la description ci-dessus a surtout mis l'accent sur des exécutions de mobiles avec des éléments rapportés, qui permettent d'abaisser le coût matière, l'utilisation de ces alliages comportant au moins de l'argent et du palladium pour des mobiles monobloc est tout à fait possible également.Naturally, even if the above description has mainly focused on versions of mobiles with attached elements, which make it possible to lower the material cost, the use of these alloys comprising at least silver and palladium for monoblock mobiles is also quite possible.
