One-Minute Tourbillon – Three Golden Bridges No. 1 Girard-Perregaux, Chaux-de-Fonds, "Chronometre Tourbillon" No. 1. Made in 1982. Extremely fine and very rare, large, 18K yellow gold hunting-cased keyless pocket chronometer with Perregaux caliber one-minute tourbillon carriage, pivoted detent chronometer escapement, Guillaume balance, three golden bridge movement. Four body, "pomme et filet", solid, polished and engine-turned, stepped back and front covers, vacant cartouche, engine-turned interior covers. Hinged gold cuvette, glazed gold-rimmed cover for viewing the movement. White enamel with radial Roman and outer Arabic numerals, outer minute track, subsidiary seconds. Gold Louis XV hands. Notes An exact replica of the watch in the Girard Perregaux Museum, this magnificent pocket chronometer with one minute tourbillon regulator "sous trois ponts d'or" is part of a very small series started in 1981 and planned to be produced in twenty examples (to date only 17 pieces have been completed; these are regarded by collectors as the most beautiful tourbillons ever made). Fitted with a pivoted detent escapement mounted on a one minute tourbillon carriage, they are identical to the original watch, patented in March 1884. A period model was acquired at auction to provide the required reference. The present watch, the first of the series of these new tourbillons with three gold bridges, was ready by December, 1982. An objective evaluation of that achievement can be foun
