AI Technical Summary
Technical Problem
The assembly of larger watch components, particularly those requiring orthogonal mounting to the mainplate, is complex due to interactions with other components and potential play between components, making it difficult to achieve precise alignment.
Method used
An assembly system using studs and notches with flexible elements that secure components together, allowing for perpendicular mounting and eliminating play by elastic retention, facilitated by a spring mechanism for additional stability.
Benefits of technology
This method simplifies the assembly process, ensures precise alignment without play, and allows independent adjustment of rate and index settings in mechanical watches.

Abstract
The invention relates to an assembly for a timepiece movement, said assembly comprising a first timepiece part (22), for example a pendulum plate, and a second timepiece part (30), for example an actuator of an actuation system, the assembly (1) comprises a fitting mechanism for fitting together a first timepiece part (22) and a second timepiece part (30), said fitting mechanism comprising at least one first boss (43) arranged on the first timepiece part (22) and at least one first groove (41) arranged on the second timepiece part (30), inside which a first flexible element (48) is arranged, and the first convex column (43) is kept in the first groove (41) through the pressure applied to the first convex column (43) by the first flexible element (48).
