A spectacular grand complication — this Girard-Perregaux Minute Repeater Tourbillon with gold bridges (reference 99820D52A931) unites two of the most prestigious mechanisms in haute horlogerie. In 18K pink gold with a diamond-set bezel, the 45 mm case frames a fully skeletonized dial that dramatically reveals the manual-winding Calibre GP 9500, showcasing the visible minute repeater gongs/hammers alongside the tourbillon carriage.

The iconic “Bridges” architecture enhances both sound and aesthetics, creating a bold yet refined presence. Engraved “OR N° 3” on the caseback adds special distinction.
