AI Technical Summary
Technical Problem
The assembly of bulky watchmaking components, especially those requiring orthogonal alignment, is complex and prone to play between components, making existing assembly methods difficult and inefficient.
Method used
The use of a stud and notch assembly system with flexible elements, where the stud is inserted into a notch with a flexible tab, allowing for secure perpendicular alignment and absorption of potential play between components, facilitated by additional notches and springs for maintaining orthogonal contact.
Benefits of technology
This method simplifies the assembly of watchmaking components by ensuring a secure, play-free connection, making it easier to assemble components perpendicular to the plate and maintaining their position effectively.

Abstract
The invention relates to an assembly for a timepiece movement comprising a first timepiece component (22), for example a balance bridge, and a second timepiece component (30), for example an actuator of an actuation system, the assembly (1) comprising means for assembling the first timepiece component (22) against the second timepiece component (30), the assembly means comprising at least a first stud (43) arranged on the first component (22) and at least a first notch (41) arranged on the second component (30), the first notch (41) comprising a first flexible element (48) arranged inside, such that the stud (43) is held in the first notch (41) by pressing of the flexible element (48) on the stud (43).
