Aerial ballet

The Girard-Perregaux Biaxial Tourbillon takes the tourbillon to another dimension –  the cage rotates on not one axis, but two. According to the watch manufacturer, this “genuine aerial ballet” enables the tourbillon to make multi-dimensional rotations and achieve excellent rate precision. “An internal cage bearing the balance, balance spring and escapement completes one complete turn on its axis in forty-five seconds,” says the company. “An external cage completes one revolution in one minute and fifteen seconds, enabling a rotation on its second axis. A full revolution is completed in three minutes and forty-five seconds.” In addition, the white gold timepiece is limited to 33 pieces.
