The Ultra-Thin Tourbillon Skeleton is powered by the A&S8220 caliber with a case height of just 8.34 mm in thickness, making the timepiece the thinnest skeleton tourbillon ever produced. Developed, designed, and manufactured entirely at La Joux-Perret Manufacture - Arnold & Son's parent company – the movement had to be redesigned and re-engineered to realize this skeleton version.
