The world’s first watch powered by a visible tourbillon movement by Patek Philippe. The 28-jewel movement consisting of 336 parts is based on the manually wound famous Patek Philippe Caliber R TO 27 PS. The Gyromax balance beats at 21,600 semi-oscillations per hour.

This amazing movement well displays the intense workmanship associated with the engraving and guilloché as well as the skeletonized modifications of this unique tourbillon minute repeater’s plates and bridges. The base plate was skeletonized to show off the Tourbillon through the dial. The base plate is also coated with blue platinum, a signature element of GRIEB & BENZINGER.


The original gold drive wheel for the tourbillon was replaced by a mysterious wheel. The movement is completely new-decorated. Every single part was treated, skeletonized, guilloché and rhodium- or rose gold-plated. The visible spring barrel and the wheels were guilloché.

All strike train parts including two polished steel hammers with two gongs, levers and springs were polished and beveled. The movement was disassembled several times before finally being reassembled in order to guarantee all functions, even those applying to the additional modifications.
