Abstract
A horology movement including at least one barrel (11, 12) and a device for displaying a power reserve (10), including a winding mechanism having a winding train (22), a reduction train (15) meshing with the or one of the barrels (11; 12), a differential gear (13) arranged so as to kinematically join the winding train (22) and the barrel (11) via a first entry on the differential gear (13), the differential gear (13) including a second entry by which it is joined to the reduction train (15), and including an exit, a power reserve display module (16) including a planetary mechanism (160) engaging with the exit on the differential gear (13).
Claims10
A horology movement comprising at least one barrel (11, 12) and a device for displaying a power reserve (10), the horology movement being characterised in that said device comprises:
- a winding mechanism comprising a winding train (22),
- a reduction train (15) meshing with the or one of the barrels (11;
- 12),
- a differential gear (13) arranged so as to kinematically join the winding train (22) and the barrel (11) via a first entry on the differential gear (13), said differential gear (13) comprising a second entry by which it is joined to the reduction train (15), and comprising an exit,
- a power reserve display module (16) comprising a planetary mechanism (160) engaging with the exit on the differential gear (13).
121, both meshing with an intermediate wheel (20), the first barrel (11) comprising a drum (110) joining it to the differential gear (13) and the second barrel (12) comprising a drum (120) joining it to the reduction train (15).
