Abstract
The balance wheel, particularly for a timepiece movement, provided with an adjustment device of its inertia to adjust its frequency of oscillation, comprises a rim ( ) of circular shape, free from projecting portions, connected by radial arms ( ) to a hub ( ). At the intersection of each arm ( ) with the rim ( ) the latter comprises a recess ( ) opening on one of its surfaces, the bottom of this recess ( ) comprising a passage ( ) opening on the other surface of the rim ( ). Balance weights ( ) having a general U shape are introduced into these recesses ( ) by resilient deformation, these balance weights ( ) being held in the desired angular position within corresponding recesses ( ) by friction due to the resilience of these balance weights ( ) themselves.
