Girard-Perregaux’s Gyromatic timepiece came out in 1957 and offered improved automatic winding by way of a two Gyroton wheels, with 7 jewels each to reduce friction. The result, at the time, was faster and more reliable winding.
By the 1960s, GP introduced the Gyromatic in a high frequency version (5hz/ 36,000 mph), up from the earlier (2.5Hz/18,000 vph and 3Hz/21,600 vph) models. This year, Girard-Perregaux introduced the Heritage 1957, that has neither the Gyromatic winding system nor the high-frequency movement. What is does share with the Gyromatic, however, is a similar aesthetic.
