The Savoie 8B watch movement belongs to a family of movements that show significant similarity to the Femga 500, 502, 520, Precimax 250SC, 400, and 450 movements. However, the specific relationship between the French Femga and Swiss Precimax remains unknown. Further examination of additional samples may help clarify this uncertainty. The Savoie 8B movement features manual winding functionality and includes a sub-second display.
