know-how of the watchmaking craftsmanship, allows them to create and direct high quality watches and movements from the assembly stages all the way to the final encasement. Girard-Perregaux designs, manufactures and develops its own movements: a large collection of high-end watch making movements, of which the Tourbillon with three gold bridges is the emblematic piece. a complete range of mechanical movements at automatic reassembly (GP2700, GP3200, GP3300, GP4500), that can fit all the types of watches, all by serving as the base for the module constructions of mechanisms with complications. Quartz movements Notable patents The Manufacture has approximately 80 patents in the watchmaking domain and is the originator of many innovative concepts. 1965: Girard-Perregaux designed the first mechanical movement at high frequency, with the balance beating at 36,000 vibrations/hour: the Gyromatic HF. 1967: Girard-Perregaux receives the Centenary Award from the Astronomical Observatory de Neuchatel in recognition of the accomplishments of the Manufacture generally, and specifically for the Observatory Chronometer wristwatch that used the Gyromatic HF movement. 1970: Girard-Perregaux presents its first wristwatch to the world to be equipped with a quartz movement and the following year a second one which vibrates at 32,768 hertz, the frequency remaining the universal standard for quartz watches today. 2008: Girard-Perregaux presents prototypes of a constant-force escapement, distinguishing itself from all the other known escapements to this day. The first watch housing the constant escapement is presented in 2013. 2016: Girard-Perregaux re-launches its model Laureato, born in the 1970s, in the form of a limited edition of 225 timepieces. In 2017, the Laureato became a full collection. Notable models Tourbillon with three gold bridges It is the emblematic model of Girard-Perregaux. In 1884, Constant Girard submitted to the United States Patent Office a patent of the design of the movement “Tourbillon with three gold bridges.” The three bridges were redesigned in the form of arrows and placed parallel to each other. The movement was no longer just a functional and technical element, but it also became an element of design in every way. In 1889, the Tourbillon with three gold bridges was awarded a gold medal at the Universal Exposition of Paris. In 1980, Girard-Perregaux decided to make 20 pieces to conform to the original of 1889: 1500 hours of work were necessary to create the first one. To celebrate its bicentenary in 1991, the company created a miniaturized wristwatch version of its famed Tourbillon
