Abstract:
     The invention concerns a watch with a mechanical movement of the type comprising at least two regulating systems (SR 1 , SR 2 ) each including a mechanical oscillator and an escapement. The movement includes as many sub-assemblies (SE 1 , SE 2 ) as there are regulating systems, each of said sub-assemblies including a regulating system (SR 1 , SR 2 ), a barrel (B 1 , B 2 ) and a going train transmitting energy from the barrel to the regulating system inside the sub-assembly. A differential display gear (Da) connects the barrel or the going train of each sub-assembly to the display (A) to average out the rate of the two sub-assemblies. In a preferred embodiment, the two sub-assemblies are mounted on a common rotating support ( 5 ) and their regulating systems are tourbillons which make an orbital movement about the centre of the watch dial.
