The Patek Philippe Grande Sonnerie is a marvel of horological craftsmanship, featuring a manually wound Caliber GS 36‑750 PS IRM movement. This exceptional timepiece offers a grande sonnerie, petite sonnerie, and minute repeater with chimes on three classic gongs, complemented by movement and strikework power reserve indicators and a jumping small seconds. The dial is a stunning Grand Feu black enamel with a glazed finish and gold-applied Breguet numerals, set on an 18K gold plate. Housed in a platinum case with a diameter of 44.8 mm and a height of 12 mm, it is humidity and dust-protected but not water-resistant. The watch is secured with a shiny black alligator leather strap and a fold-over clasp.
