Girard-Perregaux Minute Repeater Flying Bridges
Girard-Perregaux has long been regarded as a cutting-edge manufacture, creating the iconic Three Bridges tourbillon — a spectacle of precision, technical prowess and aesthetic beauty — as far back as the 19th century. With a host of high-complication watches under its proverbial belt, the brand nonetheless continues to push forward with new mechanical developments, unveiling several new movements in just the past few years. The newest comes in the form of the Minute Repeater Flying Bridges, a striking grand complication that combines three demanding feats of watchmaking: a minute repeater, a flying tourbillon and an automatic winding system with a micro-rotor.
Each watch is assembled from start to finish by a single master watchmaker — Jean-Luc Borel, a veteran of more than 25 years at the manufacture — who spends approximately six weeks completing each piece
What makes this watch particularly compelling is not simply the combination of complications, but the way Girard-Perregaux has re-conceived the architecture to serve both acoustics and aesthetics. Minute repeaters — watches that chime the time on demand — are among the most revered complications in haute horlogerie. They are also notoriously difficult to engineer, requiring watchmakers to master the mechanics, materials and case construction to achieve a clear, harmonious sound and engineers to ensure the tones and balance.
In this new model, the brand’s signature Flying Bridges design provides an open-worked stage on which the mechanism can be both seen and heard. The result is a watch that feels as much like a mechanical instrument as a timekeeper.
The Girard-Perregaux Minute Repeater Flying Bridges retails for $590,000.
The timepiece is powered by the newly developed Caliber GP9530, a self-winding manufacture movement that underscores the brand’s commitment to innovation. Automatic minute repeaters remain relatively rare in the watch world because the rotor system must operate silently so as not to interfere with the delicate chiming mechanism. Girard-Perregaux addresses this challenge with a jewel-mounted white-gold micro-rotor that winds the movement discreetly while maintaining acoustic purity.
Technically, the caliber is formidable. Measuring 43.55 mm in diameter and 10.75 mm thick, the movement comprises 475 components and delivers a power reserve of at least 60 hours. It operates at 21,600 vibrations per hour and integrates a flying tourbillon that doubles as the small seconds display. The open-worked architecture offers a contemporary interpretation of the manufacture’s historic Three Bridges layout, with arrow-tipped bridges rendered in pink gold and arranged for visual symmetry.
Every component of the new movement is hand finished and hand assembled.
Equally important is the attention paid to sound. The mainplate and bridges are crafted from titanium, a material chosen for its lightness and rigidity, allowing vibrations to travel efficiently through the movement. The gongs and gong stud are formed from a single piece of metal to preserve tonal purity, while the centrifugal regulator — which controls the tempo of the strike — is positioned on the back of the movement to minimize audible interference.
The case itself also plays a role in the acoustics. Domed sapphire crystals on both the front and back form a sealed “sound box” designed to amplify the chime, while the monobloc case integrates a newly engineered slide piece to activate the repeater and still maintain water resistance to 30 meters.
More than 440 hours are devoted to decoration and assembly of the movement components, including more than 1,000 hand-finished angles that catch the light throughout the skeletonized structure. Each watch is assembled from start to finish by a single master watchmaker — Jean-Luc Borel, a veteran of more than 25 years at the manufacture — who spends approximately six weeks completing each piece.
Housed in a 46mm 18-karat pink-gold case and priced at $590,000, the Minute Repeater Flying Bridges is not a limited edition. Yet given the incredible level of craftsmanship involved, production will likely remain below eight pieces per year — making it one of the most exclusive pinnacle expressions of the brand.
