Abstract

Timepiece sub-assembly including a spacer for guiding a pivoting wheel set on a bottom plate and including a shoulder for cooperating with a housing in the bottom plate and a stop surface for abutting against the bottom plate. It includes a drive means fixed to the wheel set, arranged to slide relative to the spacer with an axial shake, determined between a first stop position between a collar of the wheel set and a front face of the spacer, and a second stop position between a stop surface of the drive means and a rear face of the spacer. The wheel set includes, opposite the collar, a machined portion arranged to cooperate with a complementary machined portion of a display element to fixedly secure the display element to the wheel set.
