This is worldwide the first visible skeletonized tourbillon on a manual winding Patek Philippe base. This movement is the legendary Caliber R TO 27 PS with Gyromax balance, which beats at a frequency of 21,600 vph.

THE MYSTERIOUS POWER WHEEL

This special movement shows very impressively the exceptional individualization that Hermann Grieb and Jochen Benzinger can make possible. The hand skeletonization reveals a view of the tourbillon, which is unique in the history of Patek Philippe tourbillons. But that’s not all: the golden tourbillon power wheel was replaced by a “mysterious” example made of sapphire crystal. Uniqueness knows no boundaries.
