Abstract (en)
[origin: CN111913381A] A balance for a horological movement, including rigid parts constituted by a hub defining the pivot axis of the balance, at least one felloe sector, at least one arm connecting the at least one felloesector to said hub, and including a slot for receiving and gripping in position an inertia-block, the slot opening into a housing delimited on the one hand by a rigid part of the balance, and on theother hand an elastic arm including a first end integral with a rigid part of the balance, and a second free distal end. The elastic arm can have a body of a non-constant section, a part of the body having a greater thickness than the rest of the elastic arm so as to have a larger volume of material under stress and store a maximum of elastic energy.
