Fine and rare late-1960s Heuer Autavia Mark 3 stainless steel chronograph powered by the Valjoux 7730 manual-wind movement. Features a striking black and white "Reverse Panda" dial with original signed crown, sharp case bevels, and unpolished stainless-steel finish. The bi-directional rotating bezel and handset appear fully original, with stable tritium lume showing beautiful vintage character. This Autavia is in very good condition overall, with only light wear consistent with age. A classic example of Heuer's racing chronographs of the 1960s, admired for their balanced dial design and robust Valjoux mechanics. Recent appraisal completed by Smith & Bevill Jewellers in Beaverton, Oregon, documenting condition and originality.
