Heuer fans know this one: the famous Autavia Rindt. It's one of the highly-sought after vintage chronographs, made famous by German Formula One driver, Karl Jochen Rindt.
This is a 3rd execution mode, with a large 38.5mm case, carved lugs, and a matching narrow 12-hour black rotating bezel.
Perfect in every way.
Under the hood is the vaunted Valjoux 72, of course. Serviced and ready to go.
