Girard-Perregaux Tourbillon Tri-Axial
Baselworld - Designed on three planes, the Tri-Axial Tourbillon optimizes its performance and showcases a captivating spectacle.
The Tri-Axial Tourbillon by Girard-Perregaux features a regulator on three separate axes. At its heart beats a traditional tourbillon. Its cage performs one rotation in one minute. It is integrated within a structure positioned on a second axis and performs a complete rotation in 30 seconds. Finally, both are inserted into a third system. The ensemble is placed on a third axis and performs one rotation in 2 minutes. The diameter of the ensemble comes to 13.78 mm.
With a total weight of 1.24 grams, the cage and the drive systems are made of steel. The support pillars are in titanium, or in pink gold to act as a counterweight where the kinetic balance required this. As for the balance, it integrates 16 pink gold adjustment micro-screws. It has an increased frequency of 3 Hz, or 21,600 vibrations per hour.
Displaying hours, minutes and a time reserve indicator, the new GP09300 mechanical caliber with manual winding measures 36.10 mm in diameter with a height of 16.83 mm. It comprises 317 components and has a minimum power reserve of 52 hours.
The Tri-Axial Tourbillon caliber remains absolutely faithful to the purest of traditions. The cage adopts the lyre shape that has been characteristic of Girard-Perregaux Tourbillons since the 19th century. The components are decorated and finished by hand with the greatest care. They present mirror-polished surfaces and perfect chamfering (especially on a number of inward angles which are particularly difficult to finish). The gear train is circular-grained and the sides are satin-brushed. On the case-back, the eagle, the symbol of the manufacture since 1897, is engraved and a plaque in the arrow shape of the Tourbillon with Three Bridges' iconic bridges bears the individual number of each piece. This shape is also found on the emblematic gold bridges also visible on the back of the movement.
Ever since 1791, Girard-Perregaux has been pursuing its course in the best tradition of Fine Watchmaking. The Maison’s history has been characterised by legendary timepieces that combine cutting-edge design with innovative technology.Find out more >
