The inventor of the tourbillon regulator is introducing its Classique Tourbillon Extra-Plat Automatique in a “Grand Feu” enamel version. This new Classique Grandes Complications 5637 provides a beautifully simple interpretation of the tourbillon, which reigns supreme on a minimalist dial. Pared-down to its bare essentials, the unmistakable sheen of grand feu enamel is adorned only by the essentials: hour and minute hands, a tourbillon carriage with small seconds and Breguet numerals. Unlike the previous Classique Tourbillon Extra-Plat, introduced in 2013, there is no power reserve indicator on this new edition. The hand-bevelled tourbillon bar is dopped by a blue spinel, matching the blued steel Breguet hands. The in-house movement, Caliber 581, features a patented high-energy barrel to maximize energy retention.
