Original Girard-Perregaux Gyromatic automatic movement, Calibre 47BF, offered as a complete assembly including the dial, hands, and inner retaining ring. The renowned Gyromatic series was one of Girard-Perregaux’s important automatic movement families, produced during the mid-20th century. These movements helped establish the brand’s reputation for reliable and innovative automatic watchmaking and remain of interest to collectors and restorers today. This movement is sold primarily for restoration, repair, or replacement purposes. The balance appears to be intact and free-moving, although the movement has not been serviced and may require cleaning, lubrication, adjustment, or further repair due to age and storage conditions. The dial shows some light scratches consistent with age and use. The hands are present but require correction. An inner retaining ring is included.
