Symmetry and skeletonization are two traits that should come to mind whenever Arnold & Son is mentioned, and the Tourbillon Chronometer No. 36 is certainly no exception. Drawing inspiration from the John Arnold pocket chronometer No. 1/36, which will mark its 240th anniversary in 2018, the Tourbillon Chronometer No. 36 is a commemorative creation leading up to the milestone year for the historically significant John Arnold chronometer.
