Tourbillon with Three Flying Bridges Bucherer BLUE
Features
In 1867, Girard-Perregaux unveiled the ‘Tourbillon with Three Gold Bridges’ and an icon was born. Unusually, the bridges, three functional parts typically hidden from view, were made an aesthetic element. By taking this decision, the Manufacture became known for making the invisible visible. This approach has been employed on several subsequent Girard-Perregaux models. With the advent of the Tourbillon with Three Flying Bridges Bucherer BLUE, the Maison perpetuates this design philosophy but with a few fascinating twists along the way.

The three bridges not only support the geartrain, barrel and tourbillon, they also act as the mainplate. The result is that the bridges appear to float in mid-air, seemingly untouched by gravity. This unusual construction required the Maison to affix the indexes to the flange which in turn is attached to the case. The tourbillon is positioned to the base of the dial. Its cage is lyre-shaped, a historical design dating back to the 19th century, albeit in this instance it is made of ultra-modern Grade 5 titanium. A blued hand on the cage rotates 360° every minute and serves as a small seconds display. The tourbillon cage is comprised of 79 components and weighs a mere 0.25 grams. This remarkably low mass mitigates energy consumption, thereby contributing to the movement’s impressive power-reserve of 60 hours (minimum).
