The first automatic wristchronograph of the world, the iconic Zenith A386 from 1969. This Mk2 version appears with an unpolished case and in unmolested condition. Dial and hands carry the original tritium lume. Also pushers, crown, plexi and the Zenith/Gay Freres ladder bracelet are the ones that have left the factory back in 1969/70. The El Primero 3019 PHC has recently been serviced by the former owner and is running exactly in all functions.
