Breguet Classique Tourbillon Extra-Plat Anniversaire 5365

Classique Tourbillon Extra-Plat Anniversaire 5365: On June 26, 1801, or on “7 Messidor An IX”, to use the French Republican calendar in force at the time, Abraham-Louis Breguet secured a patent in Paris for his “watch compensating for all of the inequalities that may be found in the balance wheel and mainspring”. Breguet named his invention the “tourbillon” (or “whirlwind”) in line with the common practice at the time to use terms connected to astronomy. Exactly 220 years later, the House of Breguet is paying homage to its founder’s invention, which opened up a new world of precision, stability, and elegance in fine horology.
