WATCH COMPRISING AT LEAST TWO TOURBILLONS

摘要

The invention relates to a watch comprising at least two tourbillons. In order to improve the isochronism of the mechanical movement of a watch, the regulating organs comprise at least two tourbillons (11, 12) which are mounted to a common rotating support (21) which is driven by one or more spring barrels (13), such that the tourbillons perform an orbital movement around the axis of rotation (44) of the support. The tourbillons are connected by means of respective trains to a differential gear (D), the movement of one of the elements (58, 63) thereof being blocked by friction.
