Really special Autavia prototype for sale over at Chronotrader. Watch has the high-beat 28,800 Calibre 11 movement that Heuer was playing around with. We've seen several high-beat prototypes, but only 1 or 2 of these bright orange dials. I agree with the analysis over at Facebook that the dial is most likely original- but that the hands are from a later watch and a watchmaker has assembled the parts together. Still, a very, very rare dial!!
