摘要:
A method adjusting oscillation frequency of a sprung balance assembly formed at random from balance springs and balance wheels. A production mechanism is set to limit a sample standard deviation of a single batch of balance springs to a predetermined maximum value, and to limit a sample standard deviation of a single batch of balance wheels to a predetermined maximum value within a given unbalance tolerance. The mean of the balance population is classified according to the mean of the balance springs, to obtain a difference corresponding to a maximum inertia decrease value of the balances, between extreme gaussian distribution values of balances and of balance springs. A random balance spring sample is taken from the single batch of balance springs and a random balance from among the single batch of balances. The inertia of the balance is adjusted according to a torque value of the balance spring sample.

摘要:
A balance set for a timepiece, with inertia adjustment for adjusting inertia and/or balancing and/or oscillation frequency of the balance, with a balance including an insert inserted into a recess of a felloe connected to a hub by a joining surface. The balance includes on the felloe thereof an elastic holding mechanism including two antagonistic elastic lips which, when stressed, allow insertion of the insert into the recess and which, when released, prevent removal of the insert from the recess. A sprung balance or a timepiece can incorporate such a balance.
