This is a legend in watchhistory, as it was one of the very first wristchronographs with automatic movement. This A386 is original in every single part. It´s Mk3 case is still unpolished with the original beautiful lugshape, signed crown and caseback with clearly readbable serialnumber (861D790). Dial and hands are in rare unmolested condition with still the original tritium appearing on them. It comes on the original Gay Freres ladder-bracelet (4/71) in very good condition. The El Primero is running exactly in all functions.
