Abstract: Timepiece movement (300) including a regulating system (150) and an adjustment device (200), the regulating system (150) having a frame (6), an assembled balance (4) pivoted in relation to the frame (6) about a geometric axis (A4) and having movable screws or inertia blocks (43a, 43b and 44a, 44b) for adjusting the inertia of the assembled balance (4), an elastic return system (1, 2, 3) intended to link the assembled balance (4) to the frame (6) so that the assembled balance (4) and the elastic return system (1, 2, 3) form an oscillator (100), the elastic return system (1, 2, 3) having a first elastic return element in the form of a first hairspring (1) having a first stiffness k1, a second elastic return element (2) having a second stiffness k2, and a third elastic return element (3) having a third stiffness k3, the first elastic return element (1) and the second elastic return element (2) being assembled in series between the assembled balance (4) and the frame (6), and the third elastic return element (3) and the second elastic return element (2) being assembled in parallel between the frame (6) and the first elastic return element (1).
