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.

The Xtrem-1 has a tonneau-shaped case that is available in rose gold/ white gold/platinum – for retail prices of $285,899/$290,000/$311,890.
