Balance with inertia adjustment using an insert

A method of making a balance set for a timepiece, with inertia adjustment for adjusting inertia and/or balancing and/or oscillation frequency of the balance, including a balance including a hub configured to cooperate with a balance axis perpendicular to a balance plane, and a peripheral, continuous or discontinuous felloe, connected to said hub by at least one joining surface, said balance set including at least one insert, said balance further including, at a periphery of said felloe, at least one recess for receiving said at least one insert, said insert including a complementary guide means whose profile is complementary to a guide means included in said recess, said method comprising:

• providing said balance and/or said insert with an elastic holding means arranged, in a first insertion position where said elastic holding means is stressed, to allow insertion of said insert into said recess and, in a second holding position in which said elastic holding means is released, to prevent removal of said insert from said recess;
• inserting each said insert into a said recess by stressing the elastic holding means into said first insertion position;
• releasing said elastic holding means into the second holding position after complete insertion of each said insert into said recess thereof,
• wherein said elastic holding means is configured to hold said insert in said recess in an angular pivoting position relative to a pivot axis of said insert in said recess, and
• wherein said elastic holding means is separated into a first elastic holding means and a second elastic holding means, said first elastic holding means, respectively said second elastic holding means, acting as a retaining click when said second elastic holding means, respectively said first elastic holding means pivots said insert.
