In 1801, Abraham-Louis Breguet was granted a patent for the invention of one of the greatest horological complications of all time, the tourbillon. Today, 220 years after that date, the Maison pays tribute to him with a celebratory edition of the Classique made in a limited numbered edition of just 35 pieces, as many as there are tourbillon models produced by the founder during his lifetime. What catches the eye is the tourbillon itself, located between 4 and 6 o'clock on an 18-carat gold dial, with a blued-steel upper bridge and the inscription "Brevet N°157", in reference to the number of the patent attributed to the great Master. This homage is also found on the back side with the engraving "Anniversaire 1801 - 2021" on the barrel and the mention "Brevet N°157 Du 7 Messidor An IX" on the lower bridge of the tourbillon, next to the individual number of each watch. All these mentions are hand-engraved, as is the 'Breguet' signature on the peripheral oscillating weight. Finally, on the right side of the movement is a reproduction of the authentic watercolour on panel deposited by A.-L. Breguet in 1801 along with his patent application. The case is 41 mm in diameter in pink gold and the movement used is the calibre 581, an extra-flat mechanical self-winding movement with silicon escapement and balance-spring and an 80-hour power reserve. The Classique Tourbillon Extra-Plat Anniversaire 5365 is on sale for 159,900 euros.
