Abstract
A mechanical timepiece comprising a barrel meshing with a tourbillon, this timepiece being characterised in that the tourbillon is supported by its base solely by a bearing whose external ring comprises a toothing which acts as a fixed wheel for driving a satellite pinion of an escapement of the tourbillon.
Claims10
A mechanical timepiece comprising a barrel meshing with a tourbillon, wherein said tourbillon having a base and an escape-pinion formed by a satellite pinion which meshes with a fixed toothed wheel located below said base, wherein said tourbillon is rotatably mounted inside said timepiece on a single pivot supporting said tourbillon by its base, said tourbillon being suspended by its lower part on said single pivot, and being completely free in its upper part.
A mechanical timepiece comprising a dial side, visible to a user for reading a horometric time, and a barrel meshing with a tourbillon, wherein said tourbillon is made visible from the dial side of the timepiece and is arranged at the centre of said timepiece.
A mechanical timepiece comprising a barrel meshing with a tourbillon, wherein said tourbillon is supported by its base solely by a bearing whose external ring comprises a toothing which acts as a fixed wheel for driving a satellite pinion of an escapement of said tourbillon.
A mechanical timepiece comprising a barrel meshing with a tourbillon, and means for displaying an horometric time, wherein it comprises a first gear-train forming the driving gear-train and ensuring the mechanical coupling between the barrel and the tourbillon, and a second gear-train forming the display gear-train driving the display means, this display gear-train meshing with time setting means, the first driving gear-train and the second display gear-train both meshing directly with the barrel which constitutes between said gear-trains a mechanical buffer avoiding any disturbance of the first gear-train when the time is being set.
