The new Classique Double Tourbillon Quai de l’Horloge model houses a monumental movement in the proportions of a watch. The entire exposed mechanism pivots around its axis at the rate of one full turn every 12 hours. It is propelled by two independent tourbillons, which each complete a full rotation per minute. In this way, the interconnected regulating organs perform a double revolution, simultaneously driving the tourbillon bar: the signature hours hand. It is a remarkable display, featuring a number of components made of gold, as were those of grand complication movements back in their day
The two mechanical hearts beat independently from one another, each driven by their own barrel. However, the two oscillating organs are coupled with a second pair of wheels, revolving in the central differential. This double-entry mechanism is able to determine the average rate of the tourbillons, allowing for the oscillating plate to be set in motion at the rate of one full rotation every 12 hours. As for the minutes indication, it is a classic hand in the center. The entire mechanism is equipped with a system to minimize play in the wheels, ensuring a perfectly precise display.
Yet the unique character of this timepiece is fully revealed on its back. The treasures of mechanical ingenuity assembled for the movement leave in their wake timeless poetry. The timepiece is completed with an engraving, crafted by the artisans of the Manufacture, featuring the facade of the building occupied by Abraham-Louis Breguet from 1775 onward, at 39 Quai de l’Horloge, Paris. Etched into gold, the work abounds in such meticulous detail that through the windowpanes a glimpse may be caught of the wheels of the caliber. A window into two worlds of true excellence.
