Abstract
The invention concerns the structure of a timepiece movement, more particularly the structure of the hour wheel ( ), the inside of whose pipe ( ) includes an annular bulge ( ) co-operating with an annular groove ( ) arranged on the outer wall of the pipe ( ) of the cannon-pinion ( ). Thus, the hour wheel is snap-fitted onto the movement, without it being necessary to provide an additional part for this purpose, and its toothed wheel ( ) cannot therefore be released from the motion-work pinion ( ) during transport of the movement.
