Abstract
A split-seconds device with epicycloidal train for a timepiece. The device includes a split-seconds pinion which carries a fly-back hand and is mounted to rotate freely about a rotation arbor of the timepiece; a differential having an entry wheel adapted to be kinematically connected to a power source of the timepiece; a first exit wheel kinematically connected to the entry wheel by a planetary wheel and meshing with the split-seconds pinion; a second exit wheel kinematically connected to the entry wheel by the planetary wheel; and a control lever allowing to block either the first exit wheel or the second exit wheel, such that whichever of the first and second exit wheels is released by the control lever is adapted to be driven by the entry wheel when the latter is kinematically connected to the power source of the timepiece, thus allowing to block or respectively release the fly-back hand.
