GP Tri-Axial tourbillon unveiled in white gold


Girard-Perregaux has given a sneak preview of what it will unveil at Baselworld 2015 by introducing a white gold version of its Tri-Axial Tourbillon.

In an attempt by Girard-Perregaux to increase the complexity of the watch and push the limits of innovation, it has developed a tourbillon with a regulating organ that rotates on three axes instead of the traditional single axis.

The balance performs a ballet that is more captivating because of the high rotation speed of the different carriages. The interior carriage, shaped like a lyre in the Girard-Perregaux tradition, rotates once every minute. It is fitted into a structure that rotates on another axis every 30 seconds. Finally, a third structure enables the whole assembly to rotate on yet another axis every 2 minutes. This complex mechanism is flawlessly finished, and its 140 components total only 1.24 g.

The complex architecture of this 13.78 mm diameter mechanism, and its multi-dimensional rotations led to a convex lens being incorporated into its sapphire crystal. This creates enough space for the tourbillon to revolve. A window in the side of the case at 9 o’clock lets light into the heart of the movement, allowing the mechanism to be viewed from there as well as from the back of the watch. A new feature in the white gold version is a dial with open areas that display even more of the mechanism.

It takes almost 160 hours for the watchmakers to assemble the 317 components of the movement, which is now fitted into a 48 mm diameter case in white gold. Typical features of Girard-Perregaux Haute Horlogerie collections are its bevelled bezel, curved middle and streamlined horns. The watch is complemented by a black, full-grain, hand-stitched alligator strap with a folding clasp in white gold.

The Tri-Axial Tourbillon in white gold is available in a limited edition of 10 pieces.
