Abstract
Disclosed is an adjustment method for a timepiece oscillator including a balance, a support and a flexure pivot connecting the balance to the support and guiding the balance in rotation as to the support about a virtual axis of rotation, the flexure pivot having, in orthogonal projection in a plane perpendicular to the virtual axis of rotation, an axis of symmetry which is also an axis of symmetry for the points where the flexure pivot joins the balance. In the method, the unbalance of the balance is adjusted so, in orthogonal projection in the plane, the center of mass of the balance is substantially on the axis of symmetry and at a position distinct from that of the virtual axis of rotation and chosen to reduce, and preferably render minimal, the dependency of the oscillation frequency with respect to the orientation of gravity for a predetermined amplitude of oscillation.
