In 1965, GIRARD-PERREGAUX developed & manufactured the first high-frequency mechanical movement, with a balance making 36,000 vibrations per hour. This GIRARD-PERREGAUX Gyromatic High Frequency is a well-preserved testimony of one of the company's veritable technical breakthroughs.
In 1965, GP pushed even further, as they designed the first mechanic movement at high frequency, with the balance beating at 36,000 vibrations/hour: the Gyromatic HF – the first Gyromatic movements (calibre 21 and 22) beat at 18,000vph and the second series, calibre 32, were running at 21,600vph. The Gyromatic HF was produced in 662 examples. Girard-Perregaux received the Centenary Award from the Astronomical Observatory de Neufchatel for this movement.
