David Ichim and JX Su break down the function, drawbacks, benefits, and precision of Ulysse Nardin's silicon Dual Ulysse Escapement used in the second generation of The Freak.

Swiss levers usually function with a larger, but bearable, 52° lift angle, although the tendency in recent years is to go for a reduced 49°. In comparison the total escaping angle (another term for lift angle) is low as 36° in dead-beat, detent escapements.
