The new Girard-Perregaux Minute Repeater Flying Bridges is a very special grand complication watch, built around the idea of resonance and featuring virtuoso finishing.
Excellence in mechanics and aesthetics go hand in hand. The new GP9530 calibre combines a minute repeater, a tourbillon and a self-winding micro-rotor in an openworked movement of 475 components, assembled and decorated over nearly 440 hours. Everything has been purposely arranged.
In creating this timepiece, Girard-Perregaux has treated sound as architecture. Titanium plate and bridges were chosen to help vibrations travel cleanly; the mainplate is fixed to the case to reduce energy loss; the gongs and gong stud are formed from a single piece of metal; the regulator is moved to the back; even the white-gold micro-rotor is designed to wind in silence. It is an unusually disciplined approach, and one that gives the watch real substance.
The calibre GP9530 is the manufacture’s first-ever minute repeater movement developed and produced entirely in-house. It features a silent micro-rotor with automatic winding and every design choice aimed at optimising sound, including monobloc gongs and a titanium mainplate screwed directly into the gold case, turning the entire 46mm case into a sounding board for the chimes.
That rigour feels especially right for Girard-Perregaux, because chiming watches are not some recent flourish in its story. The maison links this piece back to Jean-François Bautte, the remarkably gifted Genevan watchmaker who trained in engraving, jewellery and goldsmithing and created musical and mechanical objects, including music boxes and singing birds. Long before “manufacture” became a fashionable word, Bautte was already gathering the trades under one roof. In that sense, this watch does not just revisit a complication; it revisits an old house instinct: precision, certainly, but also craft and a touch of poetry.
Left: The symmetrical, dial-free architecture suspends the mirror-polished hammers and a flying tourbillon between two of the bridges,
turning the entire movement into a three-dimensional mechanical stage.
Right: The caseback showcases a perfectly symmetrical architecture where a silent white-gold micro-rotor mirrors the mainspring barrel,
all anchored by a flying bridge that reveals the hand-finished mechanical soul of the movement.
The visual language is just as coherent. The Three Bridges architecture, central to Girard-Perregaux since the 19th century, is reworked here in Flying Bridges form, with the third bridge shifted to the back and the whole composition opened up to let light and sound move more freely. That matters, because the bridges were never only structural. Since Constant Girard’s 19th-century work and the award-winning La Esmeralda of 1889, they have been part of the brand’s belief that a movement can be composed as beautifully as a façade.
There are details to enjoy, too: the artisan’s initials discreetly set into the movement, the 1,340 hand-polished chamfers, the lyre-shaped tourbillon cage carrying the small seconds, the rose-gold case framing all of it with surprising warmth.
Overall, this is an exceptional minute repeater that deserves to be admired… and listened to.
