Girard-Perregaux has been on a tear lately, dropping three landmark in-house calibers in under six months. Now, the Geneva watchmaker with roots dating back to 1791 has welcomed its latest arrival. The Minute Repeater Flying Bridges is a watch that stacks a minute repeater, flying tourbillon, and a self-winding micro-rotor into a single skeletonized movement. That combination, in one fully in-house caliber, occupies some rare territory.
A LEGACY BUILT ON SOUND
GP’s relationship with chiming watches is not a recent affectation. Jean-Francois Bautte, the Geneva watchmaker whose 1791 atelier sits at the origin of the brand, was already developing on-demand repeating mechanisms at the turn of the 19th century. The manufacture refined those roots through the 1800s and into the modern era, producing everything from Grande Sonnerie models to the Opera I and II, with their four-note Westminster carillon. In 1996, GP became the first to pair a minute repeater and tourbillon in a wristwatch. The Flying Bridges is the next chapter in that lineage, and it carries the weight of that history in every component.
THREE BRIDGES, REINTERPRETED
The Three Bridges architecture is the oldest movement design still in series production, first sketched by Constant Girard in the 1860s and formally patented in the U.S. in 1884. The concept placed three parallel, arrow-shaped bridges along a single axis to unify aesthetics and structure. The innovation won a gold medal at the 1889 Paris Universal Exhibition.
The Flying Bridges takes that framework and evolves it: two bridges appear on the dial side, with the third relocated to the caseback, creating a kind of visual continuity between both sides. The result is a skeletonized movement where the chiming mechanism and flying tourbillon appear to float. On the caseback, the micro-rotor mirrors the mainspring barrel, delivering the kind of symmetrical composition GP has been obsessing over for 160 years.
Sounds Good
The new Caliber GP9530 is a 475-component movement assembled entirely in-house, and acoustic performance drove nearly every technical decision. The mainplate and bridges are titanium, chosen for its rigidity and vibration propagation. The mainplate is screwed directly to the case, ensuring that vibration from the gongs can travel uninterrupted into the pink gold case. The gongs and their support block are milled from a single piece of metal, eliminating any joints that might absorb sound. The centrifugal strikework regulator is hidden on the movement’s reverse side to keep mechanical noise away from the chime, and the hammers are positioned on the dial side for cleaner sound projection. The melody is furthere amplified thatnks to box-type sapphire crystals on both front and back. Meanwhile, the white gold micro-rotor is jewel-mounted rather than ball-bearing-mounted, so it rotates silently. Even winding the watch mid-chime won’t muddy the tone.
Skeleton Dance
The skeletonization itself serves the acoustics. The open architecture lets sound reverberate freely inside the case rather than getting trapped or dampened by dense movement mass. It is one of those rare instances where the visual choice and the technical choice serve the exact same goal. Assembly is handled by a single watchmaker, takes around 440 hours, and includes hand-polishing over 1,340 chamfers, 295 of which are the notoriously difficult interior angles. Each finished movement is initialed by its maker, a small plate engraved with their initials tucked discreetly into the movement.
Size Matters
At 46mm and 17.9mm tall, this is a large watch. Space is a requirement for repeater acoustics, and GP is not apologizing for it. The 30m water resistance is not amazing by itself, but is certainly a remarkable engineering feat for any minute repeater, achieved via an innovative monobloc case-middle with an arrow-shaped integrated slide mechanism, rather than the traditional open-gap approach. Lastly, the watch gets paired with a black rubber strap with fabric texture.
