Audemars Piguet Royal Oak Rose Gold Blue

Unlike a traditional tourbillon (which is mounted with a bridge that connects it to the movement on both sides), this particular reference, as noted in the model’s name, features a “flying tourbillon”. Invented in 1920 by master watchmaker Alfred Helwig, the flying tourbillon is mounted from the bottom, appearing to the eye as being unconnected and like it is hovering within the movement, making for a spectacular display.
