This grand complication is the premiere in the history
of watchmaking, combining a one-minute flying carrousel
and a minute repeater with cathedral chimes.
The watchmaking brands capable of making a movement of such complexity are exceedingly rare. Blancpain is the only Manufacture to have developed an entirely new minute repeater mechanism with cathedral chimes and to have combined it with a one-minute flying carrousel. When designing this avant-garde calibre, Blancpain contributed a number of outstanding innovations to the construction of a minute repeater, such as the system by which the cathedral chimes are fixed in the case so as to obtain unparalleled sound quality, and the device that protects the movement if the crown should be manipulated while the chiming mechanism is in operation.
