Introducing The Girard-Perregaux DLC Titanium Bi-Axial Tourbillon

September 13, 2012 | Girard-Perregaux

Today, Girard-Perregaux introduced a new version of the Bi-Axial tourbillon.

Presented in a 45 diameter by 18.5 mm black Diamond Like Carbon (DLC) titanium case, the new Girard-Perregaux Bi-Axial Tourbillon is a nice change for a company with 152 years of traditional watchmaking experience. The movement is as you would expect, of the highest quality and made to traditional watchmaking standards, the case, however, takes on a more avant-garde design. A perfect contrast, blending classic haute horology with a sporty black finish.

The Bi-Axial tourbillon combines two concentric cages that enable the regulating part to make multi-dimensional rotations. An internal cage bearing the balance wheel, balance spring and escapement completes one full turn on its axis in forty-five seconds. In addition, an external cage completes one revolution in one minute and fifteen seconds, enabling a rotation on its second axis. Full revolution in achieved in three minutes and forty-five seconds. As you might imagine, the movement of the tourbillon's two cages, balance wheel and escapement - on multiple axises - produces a visual treat for the wearer and any onlookers. All of this while correcting for rate irregularities in due to Earth's gravity, and therefore providing superb timekeeping accuracy.

The manufacture caliber GP E0201 was, of course, developed in-house Girard-Perregaux's workshops in La Chaux-de-Fonds. It is a manually wound mechanical movement that runs at 21,600 vph (3Hz), has 28 jewels, a Philips curve hairspring, Geneva stud, a variable inertia balance fitted with gold adjustment screws, 18K gold barrel bridges and central bridge and an impressive 72-hour power reserve (thanks to two coaxial barrels). The tourbillon consists of 113 parts and weighs just 0.80 grams.
