The Girard Perregaux 08 watch movement is an automatic movement that features two roller freewheels and a ball-bearing rotor. It incorporates a regulation gear and is based on the manual wind calibre AS 1687/1688. The automatic mechanism is a collaborative effort between Doxa, Eberhard, Favre-Leuba, Girard-Perregaux, and Zodiac. The 32.9 movement shares similarities with other calibers such as 32.19, 32.29, and 32.4, although specific differences are unknown. The movement offers several functions, including automatic winding, sweep seconds, and a calendar with the date set by adjusting the 20:40-24h period. It was predominantly used around 1965.
