摘要： A movement for a watchmaking piece comprising a frame (10, 11) defining a reference plane and, mounted thereon, a mechanical energy source, a clockwork watch movement driven by said energy source and adapted in such a way as to be able to bear means for displaying the time, and a time base comprising two balance wheels and two escapements, and a differential gear (31) ensuring a kinematic link between the clockwork watch movement and the escapements. According to the invention, the time base comprises two tourbillons (20,25) each of which is provided with a cage (19,26) bearing an escapement and a balance wheel, said cages being rotationally driven at least intermediately by said differential gear (31).
