In 1867, Girard-Perregaux unveiled the ‘Tourbillon with Three Gold Bridges’ that showcased its three functional parts that were typically hidden from view. This year the Manufacture celebrates its 230th anniversary by revisiting this iconic model and releasing the Tourbillon with Three Flying Bridges. The watch features three Neo Bridges formed of pink gold and it is the first time all three Neo bridges are made from this noble metal.
The three bridges support the geartrain, barrel and tourbillon, and also act as the mainplate. The bridges appear to float in mid-air. The upper and lower surfaces of the pink gold bridges are coated in black PVD shell. Vertical flanks of each bridge are exposed. Each bridge is manually chamfered using a small piece of boxwood, a technique employed for hundreds of years. It takes a time-served artisan one full day to achieve a perfect finish.
Various dial elements of the timepiece are positioned at different heights. Despite its complexity, the dial is simple to read, with the barrel, gear train and tourbillon arranged along a north-south axis. The barrel is positioned in the upper portion of the dial and sits above a white gold micro-rotor, using energy from the motion of the wearer’s wrist. The vertical sides of the rotor are engraved with the watch’s model name.
The tourbillon is positioned to the base of the dial. Made of ultra-modern Grade 5 titanium, the cage is lyre-shaped. A blued hand on the cage rotates 360° every minute and serves as a small seconds display. The tourbillon cage includes 79 components and weighs a mere 0.25 grams. This remarkably low mass reduces energy consumption.
Located atop the dial, the sapphire crystal has gently sloping sides that curve downwards to the outer edge of the case middle. To achieve this eye catching aesthetic, it takes between four to five times more material than a regular sapphire crystal.
Priced at CHF 138,300 (around USD $156,000), the Tourbillon with Three Flying Bridges is available worldwide in all authorized Girard Perregaux retailers.
