Tourbillon Watches
Invented by Abraham-Louis Breguet in 1801 to counteract gravity's effect on a pocket watch's balance wheel. In a modern wristwatch, a tourbillon is purely a horological flex — but a magnificent one. The AP Royal Oak Concept Flying Tourbillon, Richard Mille tourbillons, and F.P. Journe Tourbillon Souverain all live here.
