Ultrathin Tourbillon Skeleton

The Ultrathin Tourbillon Skeleton is powered by the A&S8220 calibre 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.
