Designed to counteract the perturbations
induced by gravity on the accuracy of watches,
the carrousel is a rare and fascinating complication.
Blancpain has revived this device and incorporated
it into a wristwatch for the first time.
Like the tourbillon, the carrousel counteracts and neutralises the effects of deceleration and acceleration of the balance wheel caused by the gravitational attraction of the Earth. The balance wheel and escapement, the regulating organs of a watch, are influenced by gravity when they are positioned vertically. But when rotated by a tourbillon or a carrousel, they pass through all vertical positions in succession, cancelling out these inaccuracies.
A tourbillon consists of a rotating carriage; a carrousel, in contrast, consists of a platform on which the balance wheel and its bridge go round like a wooden horse on a merry-go-round, the reason for its name.
Blancpain has achieved a world first by reviving this complication, almost forgotten for more than a century, and using it in a wristwatch. Incidentally, the carrousel from the Manufacture of Le Brassus is the first to have a carriage that completes one revolution in exactly one minute.
To allow the owner to admire this ingenious system, the carrousel is visible through an opening in the dial at 12 o’clock. A refined presentation shows off this elegant mechanism, one of whose bridges takes the form of a hand displaying the seconds.
