In a white gold case, the mainplate is sanded and the openworked barrel drum opens onto the micro-rotor. The new fine features of the Girard-Perregaux Tourbillon with three gold Bridges underscore this architecture over which time has no command.
Born in the hands of Constant Girard-Perregaux in the nineteenth century, the three Bridges movement is a revolution in the history of Fine Watchmaking. With it, the mechanism becomes a design feature in its own right, extending beyond a solely technical function. The Tourbillon with three gold Bridges won supreme recognition in the form of a gold medal at the Paris International Exhibition in 1889 for bringing together all the know-how of Girard-Perregaux with an entire chapter of watchmaking history.
Within a 41 millimeter diameter, the three, arrow-shaped parallel Bridges form the perfect balance. Their geometry allows for no mistakes as any imperfection would be revealed. Entirely hand-made, the finishings require such dexterity that they can only be done by a handful of craftsmen. The Bridges are “rounded-off”: the chamfering gives them a domed shape, along their entire length, a perfect curve. Light glides and reflects off their “mirror polish” finishing, offering a captivating contrast with the matt mainplate.
At 12 o’clock, the barrel drum is skeleton-crafted to reveal the oscillation of the platinum microrotor. The tourbillon system's 80 components need to be assembled in a 10 millimeter diameter. The cage, like the escapement and pallets bridge are chamfered and hand-polished as are the gold adjustment screws.
The Tourbillon with three gold Bridges is fitted with the GP09600-0024 self-winding movement, which is entirely designed and assembled in the Manufacture’s workshops.
A pink gold version is also available.
