Please note that this auction is for the pictured PARTIAL complete movement- it’s a 1940s era Onsa Watch Co mid sized 17 Jewels full rotor Automatic with a beautiful original dial!!  The parts that are missing on this one are the entire balance assembly and bridge.  The good news is that this is a widely used (for the period) Felsa F 700 base caliber ebauche- used by many more companies than just Onsa.  The winding rotor of the movement does swing well and has minimal sag.  The original 21.1mm diameter waffled dial is excellent.  The hands are original and very straight but are missing some paint.  NO RESERVE!!
