According to the invention, the second toothing (113, 113′) is formed in a single piece with the plate (103, 103′) of the first toothing (108, 108′) so as to reduce any problems of alignment of one in relation to the other and to decrease the overall mass of the wheel set (100, 100′).The invention concerns the field of timepieces.
