Abstract

The invention relates to a detachable timepiece assembly (1), which comprises a bar or bridge (2) positioned on a bar-on-plate (3) through a first centering pin (6) and a second aligning pin (11). The first centering pin and the second aligning pin are in cooperation with the bar-on-plate (3) and the bar or bridge (2). The bar-on-plate (3) or the bar or bridge (2) includes a first female centering device (4) for relative centering and a gap occupying device (20). The first female centering device receives the first pin (6) by abutting against two first facets (5) forming a dihedral edge (50). The gap occupying device is configured to apply direct or indirect force to the first pin (6). The invention also relates to an escapement mechanism including the detachable assembly, a timepiece movement including the escapement mechanism, and a timepiece comprising the movement.

Description
