The story
The Premier Tourbillon is a series for people who love the mechanics—and magic—of watchmaking. Named for each of the Breitling founders, Leon, Gaston and Willy, the three watches feature the stylized square pushers and Arabic numerals that are hallmarks of the Premier line. Their symmetrical dial design, harmonious interplay of numerals and tone-on-tone colorways perfectly balance the undisputed star of the show—the tourbillon—which takes center stage at 12 o’clock. The open sapphire crystal caseback is domed to allow for full appreciation of the B21 movement, whose oscillating weight and tourbillon appear in contrasting 18k gold. Breitling worked hand-in-hand with the boutique movement maker La Joux-Perret to develop the exquisite B21 movement that takes the uncommon step of combining a tourbillon with a chronograph to make this trio of watches so distinctively Breitling.
