Abstract (en)
[origin: EP1804143A1] The time piece has a balance bridge (4) with a base (18) associated to a balance bridge deformation unit formed of an adjusting screw (34). The screw is adjusted to vary the distance between the base and a main plate (14) by the deformation of a plate (10) at level of zones (22, 24) of less mechanical resistance, which are provided on either side of a central part (20) of the plate (10) to localize deformations generated by the screw. The central part where the bearing is arranged moves relative to the main plate to adjust the shake in the balance when the plate (10) is deformed.
