Magnetic Baller, Christophe Claret X-Trem 1
March 16, 2012
The Christophe Claret X-Trem 1 features a watchmaking first retrograde hours and minutes display that uses floating metal balls, controlled via magnetism, to show the time. A 60-second tourbillon at the bottom of the dial shows the seconds. The mechanics are visible on the dial and through the clear caseback.
