Abstract

L'invention se rapporte à un résonateur (1) comportant un spiral (5) formé dans un cristal de quartz monocristallin d'axes cristallographiques x, y, z, l'axe x, étant l'axe électrique et l'axe y l'axe mécanique, et coopérant avec un balancier (3). Selon l'invention, le coefficient de dilatation (α b ) du balancier (3) est compris entre +6 ppm. °C-1 et +9,9 ppm. °C-1 et l'angle (θ) de coupe du spiral (5) par rapport à l'axe z dudit cristal de quartz monocristallin compris entre -5° et +5° afin d'appairer le balancier (3) avec le spiral (5).
L'invention concerne le domaine des pièces d'horlogerie.
