Abstract: The invention concerns a timepiece gear train including at least one pair of circular toothed elements (25, 31) with parallel axes, the elements being provided with respectively toothings that are meshed with each other so that one (25) of the elements drives the other. In order to improve transmission conditions within the gear without reducing the toothing module, the corresponding toothings of each of the two elements are multiple, each of them being formed of N coaxial, toothed rings (28a, 28b; 30a, 30b) angularly shifted relative to each other by a fraction of a pitch of the toothing. In the simplest version, each of the toothings is double (N=2), the two rings being angularly shifted by a half-pitch. The invention prevents gearing in areas located relatively far from the line connecting the centres of the toothed elements, thus reducing torque and velocity variations during the lead of a tooth.
