Technical description


The remontoire (constant force device) comprises a secondary wheel (1) assembled on a lever (2), which swivels concentrically to the cage (3) of the tourbillon. This lever stops the principal wheel which carries the second hand (4) and transmits the energy of the barrel, whereas the auxiliary spring (5) (or equalizing spring) gives its energy to the escapement. (6) This then allows the secondary wheel to release once per second, and with repetition, the auxiliary spring is re-fuelled by the principal wheel.

What is a remontoire ?
In the Toubillon Souverain, the remontoire - a constant force device - can be compared to a dam that controls the flow of water and provides constant energy to the blades of a turbine. In effect, the remontoire regulates the power to the escapement to attain greater stability in rate. The adjustable inertia weights make it possible to optimize the amplitude of oscillation; the four-armed balance beats at a frequency of 21'600 v/h.

Technical description


The remontoire (constant force device) comprises a secondary wheel (1) assembled on a lever (2), which swivels concentrically to the cage (3) of the tourbillon. This lever stops the principal wheel which carries the second hand (4) and transmits the energy of the barrel, whereas the auxiliary spring (5) (or equalizing spring) gives its energy to the escapement. (6) This then allows the secondary wheel to release once per second, and with repetition, the auxiliary spring is re-fuelled by the principal wheel.

What is a remontoire ?
In the Toubillon Souverain, the remontoire - a constant force device - can be compared to a dam that controls the flow of water and provides constant energy to the blades of a turbine. In effect, the remontoire regulates the power to the escapement to attain greater stability in rate. The adjustable inertia weights make it possible to optimize the amplitude of oscillation; the four-armed balance beats at a frequency of 21'600 v/h.
