Abstract
The going train for a timepiece has a mechanical movement having a frame (0), a barrel (1) and an escapement pinion (5) which are connected by the going train. This going train has a stepping-up epicyclic train having a first planet gear (6) with a constant rotational speed during normal operation of the movement, a second planet gear (7) kinematically connected to the escapement pinion (5), at least one satellite gear (9) each meshing with the first planet gear (6) and the second planet gear (7), and a satellite carrier (8) kinematically connected to the barrel (1) and carrying the satellite gear(s) (9).
