Abstract
In order to improve the isochronisms of the mechanical movement of a watch, the regulating members comprise at least two tourbillions mounted on a common rotating support driven by one or several barrel springs, such that the tourbillions make an orbital movement around the axis of rotation of the support. The tourbillions are connected by respective going trains to a differential gear, one of whose elements is immobilised by friction.
Claims9
A watch with a mechanical movement including two tourbillons, which are mounted on a common rotating support and coupled by gear trains to the same median element, the tourbillons being mounted between a rotating plate and a bar which form part of the rotating support, which is driven by a mechanical energy source and connected to an analogue time display device.
