To mark the date of creation of the Tourbillon by Abraham-Louis Breguet, the Breguet unveils its latest model from the Tradition collection: a timepiece featuring strong colours highlighting what has remained – from past to present – one of the most fascinating horological complications of all times.
The fusée-chain tourbillon transmission device housed in the new Tourbillon 7047 serves to optimise the regularity of the watch’s operation by guaranteeing its constant torque, whatever its winding level is. When the barrel is fully wound, it delivers its maximum force. The chain then acts on the top of the fusée and therefore on its smallest circumference. As the chain unwinds, its torque decreases yet acts in parallel on the widest part of the fusée – its base – thus ensuring the constant force of the energy is delivered.
