    Abstract: Watch or movement including a timepiece resonator movement including two RCC flexural pivots mounted in series about an intermediate rotary support and having the same virtual pivot axis, each comprising two straight flexible strips of the same length, whose clamping points opposite to this pivot axis are at the same distance with respect to this axis, and which define linear directions, forming angles, in pairs, with this virtual pivot axis, whose value expressed in degrees is comprised between: 109.5+5/[(D/L)−(2/3)] and 114.5+5/[(D/L)−(213)], or more particularly between 107+5/((D/L)−(2/3)) and 112+5/((D/L)−(2/3)), this timepiece resonator mechanism is in an advantageous variant a one-piece temperature-compensated silicon resonator.
