The Premier Tourbillon collection is designed for watch enthusiasts who appreciate the mechanics and magic of horology. Named after the founders Breitling, Léon, Gaston, and Willy, these watches feature elegant square pushers and Arabic numerals. The symmetrical design, harmonious numbers, and tonal color palette perfectly balance with the centerpiece: a tourbillon at 12 o'clock. The sapphire crystal case back showcases the 18 carat gold B21 movement, developed in partnership with La Joux-Perret. Its unique combination of a tourbillon and chronograph sets these watches apart as distinctly Breitling.
