Tourbillon for watch movement and movement comprising same

摘要

The tourbillon has a set of resonator type balance wheels (33) mounted on a roller (34), where the tourbillon is balanced with respect to a rotation axis. Frames (30) are pivotably mounted on the roller. Each frame serves as a support for the balance wheels and for a pallet (31) and an escapement mobile (32). The mobile has an escape pinion engaged with a wheel that is rigidly fixed to the roller, where the wheel is coaxial to one of the frames. An independent claim is also included for a watch movement comprising a framework and a tourbillon.
