This is the Autavia Jochen Rindt made famous — third-execution ref. 2446, black dial with white registers (the reverse panda collectors hunt), Valjoux 72 chronograph, and that clean 12-hour bezel.

The dial is original and never touched, with light, even patina; the case is sharp and seemingly unpolished, with distinct lug chamfers; the bezel shows only light scratches; it runs well; the crystal was recently replaced; and it sits on a beautiful NOS 1960s Kreisler stainless Milanese mesh. Watch only — an honest Rindt ready to wear.
