I've got this NOS genuine Heuer bezel that I bought by mistake for my Autavia (shown in photo). The metal surfaces are black whereas mine is all silver, apart from the tachy ring obviously. Is it of any interest to anyone? I paid £750 for it as I believe they're very rare and would accept the same or a swap for a good silver one. I bought the watch new in 1971. It's been sitting in the original box for years but I've fallen in love with it again! I'm new to this forum so I don't know if I've posted this in the right place. Please correct me if I'm wrong.
