Abstract
The balance wheel assembly has a metal weighting rim (4) connected by arms of plastics material (2) to a hub (5) of the same material, in which the balance shaft (1) is inserted. The hub (5) of the balance wheel also has a pin (6) made from the same plastics material, which cooperates with the forked arms (8) of the anchor (9), so as to impart the drive directly to the balance wheel. The bottom part (7) of the hub (5) cooperates with a tongue (10) extending from the anchor (9) to ensure the operation of the escapement in the case of external shocks.
