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.
