Equipped with two tourbillons, the Breguet Classique Double Tourbillon 5345 Quai de l’Horloge ref. 5345PT/1S/7XU has a price of Swiss Francs 628,000
The new Classique Double Tourbillon 5345 Quai de l’Horloge by Breguet is one of those timepieces that it is no exaggeration to define breathtaking, at least for a watch enthusiast.
The movement of this technical marvel reveals two tourbillons that set the whole plate in motion through a central differential. Each component is hand-finished, while the back of the movement is engraved with the “House on the Quai”, the Parisian building where Abraham-Louis Breguet fulfilled his life’s work from 1775 onward, at 39 Quai de l’Horloge in Paris, just on the banks of the River Seine near Notre Dame (make sure to read our "History of Breguet" for more on this).
Presented for the first time in 2006, the Double Tourbillon is now liberated from the dial, revealing itself in all of its mechanical beauty. A sculpture in motion, the exposed mechanism pivots around its axis at the rate of one full turn every 12 hours.
Abraham-Louis Breguet invented the tourbillon in 1801 as a way to compensate the gravitational forces that may affect the chronometric accuracy of a movement by incorporating the balance wheel and spring as well as the escapement (lever and escape wheel) in a mobile carriage rotating on itself. More than just a technical solution to improve the accuracy of a timepiece, the tourbillon is one of the most appreciated and fascinating horological devices.The timekeeping parts of this Double Tourbillon 5345 are very similar technically to the original creation. The steel balance springs are endowed with the characteristic terminal curve, allowing for concentric development of the spring, a solution devised by the founder of the brand and known as the Breguet overcoil. This balance spring is still shaped by hand and even the different calibrations are done manually, such as balancing the tourbillon cages. These carriages are the only ones in the current collection that feature a framework in black-polished steel – the highest degree of finishing in fine horology.
One of the most complex systems ever developed by the Breguet Manufacture, this mobile hand-wound mechanism relies on independent wheel trains. One of the two barrels is equipped with a friction bridle, similar to those used on self-winding watches. This construction allows the spring to disengage once coiled, until the second barrel is fully wound. Lastly, the crown employs a dynamometric security system, which prevents excessive winding of the springs.Stylised and rounded, the barrel bridges in steel take on the form of the letter B. All the components are straight-grained, chamfered, and even satin-brushed by hand.

The two independent tourbillons complete a full rotation per minute simultaneously driving the tourbillon bar that is also the hours hand.

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.

Comprised of 738 components, the Calibre 588N beats at the frequency of 2.5 Hz with an autonomy of 50 hours when fully wound.
