Abstract: A balance-spring, particularly for a timepiece resonator mechanism. An adjustment device include a single elongated flexible element (5) arranged in series of strip (2), connecting one end (4, 9) of said strip (2) to a fixed support (11), to add an additional stiffness to the strip (2), and having a stiffness greater than that of the strip (2). A prestressing means (6) applies at least two different stresses on the elongated flexible element (5), the first stress being provided by a tensile/compressive force directed substantially in the longitudinal direction FL of the elongated flexible element (5), and the second stress being provided, either by a force directed substantially in a direction substantially orthogonal FT to the longitudinal direction of the elongated flexible element (5), or by a torque M, preferably a bending moment, in such a way as to vary the stiffness of the elongated flexible element (5).

Abstract: An insert for a strand of a watch wristlet to manually lock and unlock the connection between the strand and a strip of a watch case, including a body and a latch, the body having a parallelepiped portion extended by a hook-shaped portion forming a housing for the strip, and the parallelepiped portion configured to be secured to the strand. The latch is hinged to the body to cause it to pivot around a hinge axis and includes a closing wall for closing the housing. The latch has locking means formed by a pin integral with the latch cooperating with a hole in the body and first return means to constrain the pin in the hole in a locking position. The latch has a length less than the length of the cavity so that when the latch is pushed manually in the direction of the hinge axis it releases the pin.
