Abstract
This spiral-spring and balance wheel regulating member includes a shaft mounted pivotably on the frame of a timepiece. The spiral spring includes at least one blade, whose inner end is designed to be fixed to the pivot shaft and whose outer end is made in one piece with a member () for connection to the frame, the rigidity of this connecting member being substantially greater than that of the spiral. The connecting member (), on one hand, and the frame () or a member () for the angular positioning of the regulating member on the frame, on the other hand, both have respective bearing surfaces which are at least partially complementary, and these complementary bearing surfaces are joined.
