Constant Girard, a gifted watchmaker of the Girard-Perregaux Manufacture, managed to fit his watches with the tourbillon in the most remarkable way.
The Tourbillon, the watchmaker unveiled in 1867 at the Paris Universal Exhibition, was marked by a distinction. Girard-Perregaux carried on his investigations of the technical and aesthetic features of the device. He designed the one-of-a-kind Tourbillon with three gold Bridges. This outstanding invention won a gold medal.
Now, Girard-Perregaux has unveiled one more unique creation - the Bi-axial Tourbillon. The horological feat united two concentric cages, allowing the regulating part to perform multi-dimensional rotations.
An internal cage that bears the balance, balance spring and escapement performs one complete rotation on its axis in 45 seconds, while the external cage performs one revolution in one minute and 15 seconds, enabling a rotation on its second axis. It means a full revolution is performed in 3 minutes and 45 seconds.
The Bi-axial Tourbillon is a truly breath-taking spectacle for any watch connoisseur, and the alternation of positions implies supreme rate precision. The sophisticated mechanism may be admired through the dial and the case back. It is remarkable that the weight of the two cages is just 0.80 grams.
Altogether, the fascinating mechanism consists of more than 110 components. Its creators opted for cage materials providing the best balance and performance - a mixture of gold, steel and titanium. The coaxial barrels, fitted with two springs each, give an advantage of a 72-hour power-reserve and a constant energy flow.
Based on the Girard-Perregaux tradition, the tourbillon architecture reveals perfectly aligned bridges inherent to Constant Girard’s creations. The straight and ideally hollowed bridge was inspired by a pocket watch dating back to the 1860s. The timepiece was awarded with a first class prize from the Neuchatel Observatory.
The Girard-Perregaux Bi-axial Tourbillon reveals elliptical decoration on the barrel that is the reproduction of the pattern on the pocket watch of Constant Girard. The bridges are satin-finished, with bevels meticulously polished by hand. The tourbillon is housed by a magnificent pink gold case, 45 mm in diameter.
